1 Executive Summary
' In August, 1997, the City of Stillwater adopted an Alternative Urban Areawide Review
(AUAR) and Mitigation Plan for annexing just over 1,800 acres on the west side of the
City. The GUAR evaluated potential environmental impacts from the development of
' this land and proposed a mitigation plan to avoid, minimize, and/or mitigate these
impacts. The cornerstone of the mitigation plan was the diversion of stormwater flowing
from Long Lake and other portions of the annexation area away from Brown's Creek — a
' designated trout stream — and instead through McKusick Lake to the St. Croix River.
Lake residents are concerned that the AUAR's proposed stormwater diversion will
adversely affect the aesthetic and recreational qualities of the lake. They have expressed
a desire to at least maintain — and hopefully improve — the physical condition and
recreational suitability of McKusick Lake in the future. The City of Stillwater is also
' concerned about the quality of McKusick Lake. At the same time, the City has made
legal and financial comittments to implement the AUAR and its mitigation plan. In order
to balance its obligation to implement the AUAR with its desire to work with McKusick
' Lake residents to safegaurd and enhance that resource, the City initiated development of a
mangement plan.

To develop the management plan, the City Council authorized this study in October
1998. To guide the study, the Council appointed a task force with representatives from
the City of Stillwater, McKusick Lake Association, the Middle St. Croix Watershed
Management Organization, the Washington County Soil and Water Conservation
District, and the MN Department of Natural Resources. This task force met four times
between October 1998 and March 1999 to develop the management strategy. The issues
driving the development of the management plan were:
• Maintaining as high a normal operating level as reasonably possible in
McKusick Lake
• Protecting water quality and preserving/enhancing the recreational
suitability of McKusick Lake
• Protecting Brown's Creek from impacts associated with development
of the annexation area
• Maintaining the diverse biotic community in the large wetland north of
McKusick Lake
• Assuring that flows discharging from McKusick Lake can be carried
safely through the City to the St. Croix River.
The first question addressed by the task force was the projected impact of the diversion
on water quality in McKusick Lake. Phosphorus levels in the lake are of special concern
because higher levels of phosphorus can increase the abundance of algal growth in a lake,
decreasing water clarity and reducing recreational suitability. An examination of
Executive Summary
' historical data collected on the lake between 1994 and 1997 showed that average summer
phosphorus concentrations ranged between 53 and 106 ppb. Inspite of the wide
' variability in phosphorus concentrations, mean water clarity values ranged only from l.1
—1.2 meters for the same period of record.
' Computer modeling to simulate the impact of the diversion on phosphorus concentrations
in McKusick Lake suggests that average summer in -lake phosphorus concentrations after
the diversion will range between 100 and 110 ppb, depending on the extent of water
' quality treatment ponding in the upstream watershed. These concentrations are similar to
those at the upper end of the historical range. Assuming historical relationships hold
between in -lake total phosphorus and water clarity, water clarity in the lake after the
' diversion should be similar to that before the diversion.
Management options were identified and evaluated by the Task Force for
' maintaining/improving the physical condition and recreational suitability of McKusick
Lake. The Task Force adopted the following recommendations to forward to the
Stillwater City Council:
' 1. The normal water elevation in McKusick Lake should be set no lower than
' 853, contingent on the donation to the City of flood easements up to the
100 -year high water elevation by all riparian landowners. The existing
water level elevation control for the north wetland should remain the same
' as it is currently. (Note: This option will protect Brown's Creek at least as
well as the preferred option in the AUAR with respect to total volume,
peak rate, and total duration of spills to Brown's Creek from the lake.)
' 2. Evaluate and develop a strategy to modify the downstream channel below
McKusick Lake to accommodate the increased flows through the lake.
3. Construct wet detention basins in the watershed as development proceeds.
' 4. Improve the recreational suitability of the lake by:
• Adopting an ordinance prohibiting use of gasoline motors on the lake.
• Installing a public canoe landing at the existing park area on the
southeast corner of the lake.
• Constructing a fishing pier.
® Securing cooperation from MnDNR to stock gamefish periodically.
® Installing a winter aeration system, if needed.
• Developing trails connecting the lake with other areas of the City.
5. Improve shoreline management of the lake by, at a minimum, developing
' a shoreline management demonstration area on the City -owned land near
the lake outlet.
6. Adopt non-structural methods of protecting water quality, such as
1 improved street sweeping and public education.
A public information meeting was held on February 25, 1999 to review these
recommendations. Based on comments received at the meeting, the affected public
endorses the strategy developed by the Task Force.

-FINAL REPORT -
tIntroduction
' In August, 1997, the City of Stillwater adopted an Alternative Urban Areawide Review (AUAR)
' and Mitigation Plan for annexing just over 1,800 acres on the west side of the City. The AUAR
evaluated potential environmental impacts from the development of this land and proposed a
mitigation plan to avoid, minimize, and/or mitigate these impacts. The cornerstone of the
' mitigation plan was the diversion of stormwater flowing from Long Lake and other portions of
the annexation area away from Brown's Creek - a designated trout stream - and instead through
1 McKusick Lake to the St. Croix River.
' During the last fifty years, the quality of McKusick Lake and its recreational value have
changed. These changes have occurred mainly as a result of development and consequent
stormwater runoff from areas adjacent to the lake. In addition, a dike was constructed at the
north end of the lake which diverted flows from the upper reaches of Brown's Creek and spring
discharges away from the lake. Lake residents are concerned that the AUAR's proposed storm
' water diversion will affect the aesthetic and recreational qualities of the lake further. They have
expressed a desire to at least maintain -and hopefully improve- the physical condition and
recreational suitability of McKusick Lake in the future.
The City of Stillwater is also concerned about the qualities of McKusick Lake. At the same
' time, the City has made legal and financial commitments to implement the AUAR and its
mitigation plan. In order to balance its obligation to implement the AUAR with its desire to work
' with McKusick Lake residents to safeguard and enhance that resource, the City initiated the
development of a management plan for McKusick Lake. The management plan was intended to
assess the current and historical status of the lake, estimate the impact of the diversion on the
' lake, and identify opportunities for improving the lake's ecological, aesthetic, and recreational
qualities cost-effectively.

IThe Issues
IA number of issues involving McKusick Lake and the AUAR Mitigation Plan were raised during
the process of drafting the AUAR. These issues formed the backdrop for the discussions that
took place on development of a management plan for McKusick Lake and are described briefly
below:
• Lake levels on McKusick Lake. The protected waters permit from the MnDNR identifies a
normal water level of 852.3 MSL for the lake. The lake level was raised to approximately
' 853.5 sometime during the 1990's without authorization from the MnDNR. Many residents
expressed great concern about returning the lake to the lower water level, and how this might
' affect the lake's aesthetic qualities and its ability to maintain a suitable water level during dry
years.
• Water quality and recreational suitability of McKusick Lake. Many residents remember
when McKusick Lake was a higher quality lake with a good fishery and a much higher
' recreational value than it has presently. Most suggested that the quality decreased
significantly when the dike at the north end of the lake was constructed in the late 1950's.
They also expressed a concern about the impacts on water quality in the lake as a result of the
proposed diversion.
• Protection of Brown's Creek. Brown's Creek is ranked as one of the six highest priority
trout streams for protection in the Metro region by the MnDNR. Adverse impacts to Brown's
' Creek associated with runoff from future development in the annexation area was the
primary environmental issue driving the AUAR. One of the key strategies adopted in the
AUAR for protecting Brown's Creek was the diversion away from the creek of all
stormwater runoff from the annexation area for up to a 3 -inch rainfall event. In addition, the
' AUAR established that backwater discharge from McKusick Lake to Brown's Creek not
occur for events less than or equal to a 5 -year rainfall (3.5 inches in 24 hours). These
standards must be maintained to provide adequate protection to the trout fishery in Browns
' Creek.
' • Protection of the large wetland north of McKusick Lake. Currently, this wetland supports a
diverse wetland plant community and is of high value for wildlife habitat, flood control, and
other important functions. Preservation of the capability of this wetland complex to support
a diverse vegetative community was identified as an important issue by MnDNR
representatives.
Lake Assessment and Action Plan for McKusick Lake 2
• Adequacy of conveyance system below McKusick Lake The capability of the conveyance
system below McKusick Lake to accommodate the increased flow volumes discharging from
McKusick Lake as a result of the diversion was also identified as a concern. Water
discharged from McKusick Lake is carried through a combination of open channels and
pipes between the McKusick Lake outlet and the St. Croix River.

Analysis and Results
1. Review of existing data
MnDNR lake survey reports for McKusick Lake for June, 1947 and June, 1958 characterized the
lake as a Type V (deepwater) wetland with a maximum depth of between 12.5 and 15.5 feet.
' The reports note that over 80-90% of the lake has a depth of 4 feet or less. June water clarity
readings for both survey years ranged between 5.5 feet and 7.5 feet (1.7-2.3 meters). Emergent
and submergent aquatic plant growth were noted as abundant, although no problem algal blooms
' were noted. Fisheries data from the surveys indicated an abundance of sunfish and northern

pike. Stillwater City Attorney Dave Magnuson, who spent considerable time on and around the
lake between 1946 and 1959, reported that the lake was known locally as a good fishery for
northern pike and that northems would swim through a culvert to reach the wetland north of the
lake for spawning (personal communication to Sherri Buss).
In 1975, a study by Lake Management, Inc. of Marine on St Croix was completed for McKusick
Lake. The study involved an examination of some physical, bacteriological, and chemical
characteristics of the lake. The study noted that dense growths and die -backs of submerged
aquatic vegetation were apparently causing very low oxygen conditions during both winter and
summer months. In addition, the study concluded that the aesthetic and recreational qualities of
McKusick Lake were hindered by the general insufficiency of make-up water from Brown's
Creek and the shallow depth of the lake. Among other recommendations, the study suggested
raising the normal water elevation of the lake and taking steps to assure a good circulation of
water from the northern end through the main body of the lake to its outlet in the southeast
corner.
Data collected on McKusick Lake through the Metropolitan Council's Citizen Assisted
Monitoring Program (CAMP) program provides the best historical information on water
chemistry, water clarity, physical condition, and recreational suitability for the lake. This data
has been collected on a bi-weekly basis between late April and mid-October since 1994. It is the
only data set available for McKusick Lake that provides information on recreation season values
for the three key parameters -total phosphorus, chlorophyll a, and water clarity -most helpful in
assessing aesthetic and recreational suitability. Phosphorus concentrations are important because
the availability of this plant nutrient often controls the amount of algae growth in an aquatic
ecosystem. The amount of algal growth (expressed as chlorophyll "a" concentration) strongly
influences the clarity of the water. Water clarity is a key physical parameter affecting user
perceptions of the suitability of a lake for recreation. In general, higher phosphorus
concentrations cause more algal growth which decreases water clarity. As water clarity
decreases, human perceptions of the suitability of the lake for recreational use also drop. Thus,
all three parameters provide important information on the condition of a lake.
A summary of the data from McKusick Lake collected through CAMP is presented in Table 1.
In general, the data confirm that the lake supports a considerable summertime algal population
that limits its appeal for recreational use. Based on these data, the Met Council has assigned
overall lake water quality grades of "D" for 1994-96 and "C" for 1997 on an A -F scale.

2. Field Survey Findings
A field survey of the lake was conducted on October 15, 1998 by staff from BRA. The purpose
of the survey was to generate a hydrographic map of the lake showing depth contours and assess
the type and relative abundance of submergent aquatic plant species in the lake. The elevation of
the lake at the time of the survey was estimated at 852.7.
Depth soundings along a series of transects were compiled to generate a bathymetric map for the
lake (Figure 1). Based on the results of this survey, approximately 80% of the surface area of the
46 -acre lake is less than or equal to 5 feet in depth; the area of the lake greater than 10 feet deep
is only about 2 acres (Table 2). These extensive shallow depths suggest the potential for
extensive colonization by emergent and submergent aquatic plants, depending on the clarity of
the overlying water during the growing season.
Qualitative sampling of submerged aquatic plants was also conducted at numerous sites
throughout the lake. The major submergent aquatic weed species found during the survey were
coontail (common), flatstem pondweed (abundant in spots), and largeleaf pondweed (rare). All
are desirable native aquatic plants that perform valuable ecological functions in a lake system,
although coontail can reach nuisance levels in nutrient -enriched systems. Neither curly leaf
pondweed nor eurasian milfoil-both exotics that can be very difficult to control- were found
during the survey. Sparse growths of coontail were found as deep as 9 feet, although moderate
to heavy growth only extended down to depths of 6-7 feet. These observations confirm that
heavy aquatic plant growth in McKusick Lake occurs at depths up to twice the recreation season
mean water clarity value of 1.1 meters (3.5 feet).
Observations were also made regarding emergent growth in the lake. Yellow pond lily and
spatterdock — both floating emergents - were noted growing to depths of 3-3.5 feet. Softstem
bulrush and cattail were observed growing to maximum depths of 1.5-2 feet.

3. Modeling -Watershed Loading and Lake Response
' a. Model Selection and Testing
' Computer model can help assess the effect of the proposed diversion on water quality in
McKusick Lake as well as provide the basis for evaluating the effectiveness of management
' options. Two types of models were selected to carry out this task. The model PONDNET was
used to generate information on phosphorus and water loads from the watershed of McKusick
' Lake under both the existing (pre -diversion) conditions and the post -diversion condition. This
model is endorsed by the Mn Pollution Control Agency for use in watersheds dominated by
' urban land uses where phosphorus — the pollutant of primary concern for McKusick Lake — is
generated by runoff.
IOutputs from the PONDNET model for phosphorus and water loading were then used as inputs
to a second modeling tool named the Wisconsin Lake Model Spreadsheet (WILMS). WILMS is
' composed of 10 empirical lake response models that were developed using monitoring data from
various lakes throughout North America, Canada, and northern Europe. The lake models predict
' either spring overturn or growing season (May -September) in -lake total phosphorus
concentrations. The lake models included in WILMS represent a cross-section of many lake
types and characteristics, are commonly used today for lake management purposes, and have
' been published in technical journals.
' PONDNET models were developed to reflect both existing and future (post -diversion) watershed
conditions for McKusick Lake. Using precipitation data collected from a Stillwater site, annual
watershed loads for phosphorus and water were generated using the existing conditions
watershed model for each of the years with CAMP in -lake monitoring data. The in -lake
phosphorus concentrations predicted by each of the lake response models were then compared
iwith the monitored values for each year. The model also provided information to ascertain
Lake Assessment and Action Plan for McKusick Lake 8
' whether the input parameters for McKusick Lake with regard to mean depth, phosphorus
loading, phosphorus concentration, flushing time, etc. fit within an acceptable range for each
' model.
' Results showed that the key parameters for McKusick Lake fell within acceptable limits for only
three of the 10 lake response models under both existing and future watershed conditions. Of
' these three models, the Reckow Anoxic Lake Model came closest to consistently predicting in -
lake recreation season total phosphorus levels in McKusick Lake for the 1994-1997 monitoring
period. A comparison of modeled vs. monitored results for this model is shown in Table 3.

b. Impact Analysis Results
Adaptation of the PONDNET models for both existing and future conditions utilized watershed
and ponding data developed for the HydroCad model as part of the preparation of the AUAR.
This information was supplemented by data on wet pond volumes (i.e. dead storage volumes) for
key lakes and ponds within the watershed. This information was generated through field checks
by City of Stillwater staff, lake bathymetric surveys, or record plans for constructed ponds.
Where natural wetlands were known to have standing water but no other information was
available, a mean depth of 1-2 feet was assumed, depending on the size and type of the wetland.
For the purpose of analyzing the impact of the diversion on water quality in McKusick Lake,
precipitation data for the 1996 water year was used in the future condition watershed analysis.
Examination of the existing data indicates that 1996 is a below average precipitation year and
that in general, water quality in McKusick Lake tends to be worse in years of below average
precipitation than in years of above normal precipitation. Thus, use of water year 1996
precipitation data was expected to provide a conservative estimate of the impacts of the diversion
on McKusick Lake.
' The pre- and post -diversion watershed areas for McKusick Lake are shown in Figure 2. Under
existing conditions, McKusick Lake has a total watershed area of approximately 940 acres
' (McKusick Lake and Lily Lake drainage districts). Construction of the proposed diversion
would introduce runoff to McKusick Lake from the Stillwater Drainage District south of County
Road 64 as well as the Long Lake Drainage District. As a result, the total watershed of
' McKusick Lake would increase to over 4,200 acres. A comparison of pre- and post -diversion
watershed loads and in -lake phosphorus concentrations for McKusick Lake is shown in Table 4.
J
1
In general, watershed modeling suggests that both phosphorus loading and water loading to the
lake would increase by around seven times as a result of the diversion. The lake response model
indicates that the predicted total phosphorus concentrations in the lake after the diversion will be
100-110 ppb for a water year with precipitation like 1996. CAMP data collected for McKusick
Lake between 1994 and 1997 showed consistent water clarity readings of 1.1-1.2 meters over a
wide range of seasonal average in -lake phosphorus values (53-106 ppb). Assuming historical
relationships hold between in -lake total phosphorus concentrations and water clarity,
water clarity in the lake after the diversion should be similar to that before the diversion.
Further, the decrease in the time it takes for inflow water to completely replace the lake
volume (the "flushing" time) may help keep algal blooms in check.

Management Options
' A number of management options were considered by the Task Force for maintaining/improving
the physical and recreational suitability of McKusick Lake as well as protecting other valuable
' resources in the vicinity. For each management option, background information on the option
was given as well as a description of advantages and disadvantages of pursuing that option. Also
' presented were an estimate of the costs of implementing the particular management option as
well as a list of the major assumptions underlying the cost estimate. For the reader's reference,
options marked with an "' were those eventually recommended by the Task Force.
Maintain operating water levels in McKusick Lake and north wetland at same
elevation (AUAR Recommended Option)
Background: This was identified as the most feasible option in the AUAR and involved
operating both McKusick Lake and the north wetland at an elevation of 852. This
televation is approximately 1.4 feet lower than the elevation at which the lake has been
operated since 1993 and about .3 feet lower than the elevation permitted by MnDNR.
' The dike at the north end of McKusick Lake would be breached so that levels in the lake
and the wetland would be equal. This would permanently inundate approximately 17
' acres of the 50 acre wetland immediately north of the lake. In order to provide adequate
protection to Brown's Creek, a dike and spillway would be constructed at the north end
of the wetland in order to contain the runoff for up to a 5 -year precipitation event.
iBecause of the low elevation of McKusick Road adjacent to the wetland, the road would
have to be raised to prevent frequent flooding.
' Advantages:
' • Provides adequate protection to Brown's Creek so that development of the annexed
area can proceed.
' ® Allows use of the north wetland to provide some treatment of diversion flows prior to
discharge to McKusick Lake.
' • Has received agency approval.
n

IDisadvantages:
' • Control water level in McKusick Lake would be lowered below both permitted and
historical elevations.
' May adversely impact vegetative and habitat diversity in the north wetland.
• Dike/spillway construction at north end of wetland and raising of McKusick Road are
' expensive.
• Wetland could eventually become a source of pollutants.

*2. Maintain operating water level in McKusick Lake at a higher elevation than that for
the north wetland.
' Background: At the request of the Task Force, an effort was made to develop an option
which would meet the following objectives:
' • provide the same level of protection to Brown's Creek as the preferred option in
the GUAR,
' • allow operation of McKusick Lake at an elevation closer to that at which it has
been operated since 1993,
' • preserve the integrity of the vegetation community in the north wetland.

Assumptions:
'
• Existing dike at north end of lake would be breached.
• Spillway of new dike at north end of wetland would be set at 854.
• Existing 21" outlet for McKusick Lake remains.
'
• A 1.5 cfs low flow bypass would be maintained to Browns Creek.
• Cost estimate for improvement of downstream conveyance system from City
'
engineering staff.

Lake Assessment and Action Plan for McKusick Lake 15
' This option appears to balance these desires. It proposes that the control elevation of
McKusick Lake would be 853 and that the control elevation for the north wetland would
' remain the same as it is currently (850-851). This option also assumes that the existing
dike between the north wetland and McKusick Lake would be raised and a spillway
' would be installed to allow discharge of water from McKusick Lake to the north wetland
under high flow conditions (Figure 3). Modeling indicates that there are several
combinations of spillway elevation and lake outlet sizes

that would allow runoff from events less than or equal to 5 -year storm to be completely
contained within McKusick Lake (no discharge to Brown's Creek via the north wetland).
Further, the Task Force expressed a desire to contain the maximum water level
fluctuation in McKusick Lake to about 2 feet and 3 feet above normal water level,
respectively, for 5 -year and 100 -year storm events. Based on survey and topographic
data, the flood threat to structures around the lake should be minimal with these water
level fluctuations.
There are three structural components associated with this option (see Figure 3). They
are as follows:
• The dike between the lake and the north wetland. This dike would be raised in
order to prevent dishcharge of lake water to Brown's Creek for small
precipitation events. The dike improvements would likely be made to
accommodate a trail. The extent of the dike improvements will depend on the
results of field investigations and the final outlet configuration for McKusick
Lake, which in turn depends in part on an evaluation of the conveyance
system below McKusick Lake.
• The inlet structure from the Browns Creek channel in the north wetland to
McKusick Lake. This structure would convey diversion flows from the
channel to McKusick Lake. It would also allow backflow from Mckusick
Lake toward the north wetland under flood conditions. Again, the cost of this
component will depend on soil conditions and the size of the structure needed.
• The inlet structure connecting the Brown's Creek diversion channel to the
north wetland. This structure would allow the option of bypassing a baseflow
to the wetland if desired and also serve as an overflow from the lake to the
wetland for runoff generated by storms greater than a 5 -year event. Again, the
cost of the structure will be determined by the size required and soil
conditions.
Because of the uncertainties, a range of costs and a contingency are included in the cost
estimates for this option.
Table 5 compares Management Options 1 and 2 to each other with regard to the peak
flows, spill volume, and spill duration to Brown's Creek from the lake for 5 -year and
100 -year events. Regardless of the assumed outlet configuration, Management Option 2
meets or exceeds the standard for protection of Brown's Creek set in the AUAR.

Advantages:
• Brown's Creek will be protected to at least the same level as the preferred option in
the AUAR with respect to the peak rate, total volume, and duration of spills to the
creek from McKusick Lake.
• McKusick Lake would be operated at a water level closer to that at which it has been
operated since 1993.
• There will be a greater chance of preserving and possibly even enhancing the
desirable vegetative and habitat diversity in the north wetland.
Disadvantages:
• The north wetland can not be used to treat diversion water prior to discharge to
McKusick Lake.

*3. Construct detention basins in watershed as development proceeds
Background: Construction of wet detention basins in the upper watershed is among the
most effective means to minimize pollutant loadings to McKusick Lake. If designed
properly, detention basins are capable of removing 40-80% of the pollutants of greatest
concern commonly found in urban runoff. The City of Stillwater has already committed
heavily to the use of detention basins that meet recognized standards for both rate control
and water quality protection for private developments as well as public improvements. If
ponds of adequate design and size are required as a condition of development, costs to the
City should be minimal. The AUAR contains recommendations for numerous ponds in
the post -diversion watershed, some of which have already been installed. It will be
important to try to assure that jurisdictions within the watershed but outside the City of
Stillwater utilize these treatment practices as well.
Advantages:
• Properly designed wet detention basins are the most effective method of reducing
urban runoff pollutant concentrations.
• If required as a condition of development, the capital costs are born by private parties.
• Ponds provide both rate control and water quality benefits.
Disadvantages:
• The City of Stillwater only has the authority to require ponds in the portion of the
watershed over which it has jurisdiction.
' Costs:
Long-term maintenance costs would likely be the responsibility of the local
government jurisdiction within which the ponds are located if the ponds are part
of a public utility system. Costs difficult to estimate at this time.
' Assumptions:
I
• Capital costs of ponding will be born by private developers or those directly benefited
by the project.

1 4. Use wetland above McKusick Lake to protect lake water quality.
' Background: If the water level in the wetland north of McKusick Lake is maintained at
the same or a higher level than the lake (as proposed in Management Option 1), it could
' be used to further treat diverted water prior to discharge to the lake. Wetlands have been
shown to be either sources or "sinks" for nutrients, in large part depending on the history
of past pollutant loadings to the specific wetland. Given the diverse vegetative
community found in this wetland and the fact that the historical pollutant loads from the
Brown's Creek watershed have flowed through channels in the wetland with minimal
' dispersion, it is likely the wetland's nutrient assimilation capacity is relatively good at
this time. However, continued high nutrient loadings in the future could change this
' condition. Thus, provisions would need to be made to allow the option of diverting flow
around the wetland directly to McKusick Lake to preserve the long term treatment
' performance of the wetland while at the same time minimizing recreation season water
quality impacts to McKusick Lake.
I
Advantages:
' • Other than on-site ponding in upstream developing/developed areas, use of the
wetland could represent the most effective method of reducing incoming nutrient
loads associated with diverted water to McKusick Lake.
Disadvantages:
• Use of the wetland for nutrient attenuation of diverted flows could decrease
' vegetative diversity.
• Over -loading the wetland's nutrient assimilation capacity could change the wetland
from a sink to a source of nutrients in the future.
• Further field study is desirable to assess the current treatment potential of the wetland.
Future monitoring and active management of diversion flows will be necessary to
' preserve the wetlands treatment capability.
I
Estimated costs:
' Assessment of current wetland condition (optional) $3,000
Construction of flow diversion structure $30,000
Future monitoring (optional) $1,500/year
Lake Assessment and Action Plan for McKusick Lake
Assumptions:
• Assessment of current wetland conditions confirms utility of wetland to act as
' nutrient trap.
• A suitable site for the diversion structure can be found.
' • Diversion flows can be dispersed throughout the majority of the wetland without
significant modifications within the wetland (ditching, diking, baffles, etc.)
• This option is only feasible if lake and wetland water levels are maintained as
' proposed under Management Option 1.
' S. Dredge McKusick Lake
' Background: The objectives of dredging the lake would be to provide enough deep
water to over -winter gamefish populations without supplemental aeration and to lower
the elevation of the lake bottom to preclude the formation of nuisance weed growths over
' a majority of the lake surface area. The MnDNR's "rule of thumb" for overwintering
gamefish without supplemental aeration is that 25% of the lake area should be 14' or
' deeper. To control nuisance weed growth to a desirable degree and still maintain
sufficient shallow water habitat, it is recommended that a total of 60% of the area be
I
below the photic zone (i.e. deeper than 7 feet for McKusick Lake).
IAdvantages:
' • Preclude the need for supplemental aeration to over -winter gamefish.
• Control and confine nuisance weed and emergent growth without additional
' management efforts.
• Could reduce or eliminate the need for road modifications and/or diking if lower
normal lake control elevation could be accommodated while maintaining sufficient
' depth for the above.
' Disadvantages:
' • Costs are high.
• Acceptability to agencies is uncertain.
' • Disposal site for the dredge material removed may be difficult to find.

Dredging $2,200,000

Assumptions:
• Mechanical dredging methods are used to remove 275,000 yds. @ $8/yd.
' • Disposal sites for dredge spoils can be found within several miles of project area; no
land purchase for disposal of spoils necessary.
' • No wetland mitigation required.
• The photic zone will not increase after the diversion
' *6. Improve recreation value and sport fishery of McKusick Lake
' Background: There is anecdotal evidence that McKusick Lake supported a stable and
viable sport fishery when Brown,s Creek was connected to the lake. Regional fisheries
personnel and long-time residents believe that the connection with the creek allowed fish
within the lake to access higher oxygen refuges -either in the wetland north of the lake or
' in Brown's Creek itself- that allowed overwinter survival. Since the construction of the
dike separating Brown's Creek from the lake, fishing quality has diminished
substantially. It is possible that re-establishment of this connection as proposed for the
diversion could obviate the need for supplemental aeration. Installation of a public
access with limited parking would be required in order to secure assistance from the
' MnDNR for lake fisheries management. Surface use zoning by the City may also be
appropriate to limit the type of watercraft that can be used on the lake.
Advantages:
' • Designation of a suitable public access site would allow the City and/or residents to
pursue MnDNR funds to help finance access improvements and purchase/installation
' of an aeration system, if needed.
• Stocking of sportfish by MnDNR could be carried out.
1
Lake Assessment and Action Plan for McKusick Lake 24
' • McKusick Lake would become more of a local recreational resource to both the
' general public and riparian land owners.
Disadvantages:
• There are no obvious good public access sites on the lake. Additional, investigation is
' needed. (Note: One Task Force member suggested that the City -owned parcel at the
southeast corner of the lake might make a suitable access for a canoe access.)
' • Riparian landowners would no longer have exclusive access to lake if the required
public access is installed.
IEstimated costs:
' Public access $20,000-$30,000
Aerator $15,000-$40,000 capital cost
' $500-$1,000/yr. for operation and
maintenance
1 Assumptions:
• Access development costs are difficult to determine until a site is chosen. The
' estimate above does not include land acquisition costs.
• Aerator costs assume an electric portable or buried pump and baffle aeration system
' and that power is available nearby.
' 7. Manage weeds through mechanical harvesting
Background: Based on historical water clarity readings and with the current lake bottom
' elevation configuration, over 80% of McKusick Lake could support rooted weed growth.
While the maximum depth of colonization by weeds was found to be about 9 feet in the
' October, 1998 lake survey, nuisance growths are likely to occur in depths of 7 feet or
less, assuming no significant change in water clarity. There is no evidence of exotic weed
species in the lake, so control efforts would be aimed at nuisance levels of native species
' (primarily coontail). Current permitting requirements by MnDNR would limit the area of
the lake that could be harvested to no more than V2 the littoral zone or about 22 acres of
' the 46 acre lake.
Lake Assessment and Action Plan for McKusick Lake 25

1
Advantages:
• Harvesting is a more environmentally sound method of weed control than the use of
herbicides.
Disadvantages:
• No access to the lake for a harvester exists currently. A suitable access would need to
be installed.
• Too much weed removal could allow proliferation of bloom algal species to
dominate, causing a decrease in water clarity and possibly making the lake less able
to support a sportfish population.
• Coontail, one of the dominant weed species in the lake, can be difficult to control
with harvesting because it becomes detached easily from the bottom under some
conditions.
Estimated Costs:
Construction of landing $20,000430,000
Harvesting ($400/ac. for 22 acres/yr.) $8,800/yr.
Assumptions:
• No land acquisition costs included
8. Use temporary winter water level drawdown to control aquatic plants
Background: Winter water level drawdowns have been shown to be effective in
controlling some types of rooted aquatic weeds, especially exotics such as curly leaf
pondweed and eurasian milfoil. The current outlet configuration would allow a
drawdown to an elevation of about 1.5 feet below the permitted water elevation of the
lake (852.3). Given the size of the post -diversion watershed, it is unlikely that the lake
would require more than 1-2 weeks to re -fill in the spring after drawdown, even in dry
years.
Lake Assessment and Action Plan for McKusick Lake 26
Advantages:
'
• The small drawdown allowed by the current outlet configuration is inexpensive.
• Control most likely for weeds with well-developed root systems.
Disadvantages:
'
• May encourage additional encroachment of cattails into open water.
g p
'
• Drawdown as a control strategy for coontail, the dominant weed species in the lake at
the time of the October 1998 lake survey, may not work particularly well because of
coontail's ability to detach from bottom substrate.
Estimated costs:

Assumptions:
' • Controlling factor in determining the maximum drawdown is the concrete sill of the
outlet structure in front of the outlet pipe.
1 • One public meeting required/desirable for public review of option.
*9. Improve shoreline management.
Background: This element would be aimed at promoting the establishment of upland
buffers extending back 20-30 feet from the water's edge while still allowing for access to
the lake for riparian landowners. Only about 20% of the shoreline exhibits undesirable
' shoreline management practices (i.e. turf grass to water's edge). The shoreline
stabilization benefits of this management item become increasingly more important as
' water levels in the lake are raised higher and/or fluctuate more.
' Advantages:
• Riparian fish/wildlife habitat and shoreline stabilization would be improved.
' • Incremental step in encouraging environmentally -friendly riparian property
management.
' • Low cost.

I*10. Pursue non-structural methods to reduce pollutant loadings to take.
Background: Non-structural options such as spring and fall street sweeping and public
education are usually key components of lake water quality management programs.
Spring street sweeping efforts are usually intended to reduce the amount of material
accumulated over the winter that is carried in runoff to lakes, while fall sweeping is
intended to intercept leave litter. Public education is designed to promote recognition of
the direct connection between storm drainage systems and lakes. Education is also
intended to promote understanding by the target audience of how to keep pollutants such
' as vegetative material, phosphorus -containing fertilizers, and chemical wastes off hard
surfaces and out of storm drainage systems feeding a lake. The most cost-effective
efforts are directed at those areas that discharge directly to the water body of concern.
These areas typically generate the greatest loadings per unit area in the watershed and
residents within the areas are usually more attuned to the condition of the resource and
therefore more receptive to the education message. However, documented reductions in
pollutant loadings as a result of public education and street sweeping are lacking. In
addition, the phosphorus load contribution from the direct drainage of McKusick Lake is
Lake Assessment and Action Plan for McKusick Lake 28

I

expected to very small compared to the load entering the lake from other areas of the
watershed.
Advantages:
• Could be relatively inexpensive if focused on the direct drainage of the lake and
combined with existing programs for sweeping and/or public education on other
environmental issues.
• Would raise the general environmental awareness of watershed residents and provide
means to help contribute to lake protection.
• May help to prevent or slow future degradation of lake.
Disadvantages:
• Would be unlikely by itself to achieve sufficient reductions in pollutant loadings to
cause any demonstrable improvement in water quality in McKusick Lake.
• Watershed -wide education efforts will get more expensive, more logistically
complex, and perhaps less effective the further from the resource the effort is
extended.
Estimated costs (annual costs):
Street sweeping (annual expenditure) $3,000
Education brochure (development/distribution) $500
Catch basin stenciling $2,000
Assumptions:
• All activities carried out in the McKusick Lake direct drainage only.
• Street sweeping activities are carried out in spring and fall (5 curb miles @ $300/curb
mile twice per year).
• MN Department of Agriculture materials modified for McKusick Lake by DOA staff.
• Public education materials mailed once per year in spring to 250 residences.
• Stencils, doorhangers, and other supplies purchased; application/distribution by
volunteers.

I Enhancement of Downstream Y
Conveyance System
Y
Another important issue identified by the task force was the evaluation and modification of the
conveyance system below McKusick Lake. Water discharged through the outlet in the southeast
' corner of McKusick Lake must travel almost a mile through a combination of pipe and open
channels before it reaches its eventual discharge point to the St. Croix River (Figure 4). At
' present, a little less than half the length of this conveyance system is enclosed in pipe. Even
under existing conditions, portions of the open channel below Everet Street are already
' moderately to severely eroded and local flooding problems have been reported further
downstream. The diversion of additional flow through McKusick Lake will mean that this
conveyance system will carry higher flows on a more frequent basis than it has in the past. With
' this change, the severity of erosion and flooding problems will increase without modification of
the conveyance system. The improvements for the downstream system would be recommended
I
regardless of which of the lake level management options presented previously is selected
' A detailed evaluation of this system was beyond the scope of this report. However, the task
force felt it extremely important to address this issue in a future investigation based on the
following:
• Prevention of channel erosion is necessary to prevent future maintenance
' issues for the City and protect the quality of the water discharged to the St.
Croix River.
' • The flow capacity of the downstream system must be adequate to prevent
property damage associated with flooding.
' • Work in the ravine could include construction of a trail through the ravine to
connect with the City's trails at McKusick Lake.
Recommendations
' On January 28, 1999, the McKusick Lake Task Force met to tentatively select the management
options to recommend to the City Council. These management options were reviewed with the
' potentially affected residents at a public information meeting held on Thursday, January 25,
1999. Input received at that meeting supported the Task Force recommendations.

' The Task Force therefore recommends the following management options for McKusick Lake:
Recommendation 1: Maintain the water level elevation in McKusick Lake at a higher level
than that in the north wetland. The water level elevation for McKusick Lake should be set
no lower than 853 feet.
' Rationale: Maintainingthe water level of McKusick Lake at the highest reasonable level w
g as a
' top priority of the lakeshore owners represented on the Task Force. This option is also the best
for preserving the ability of the large wetland north of the lake to support a diverse vegetative
community. Most importantly, it is feasible to design this option so that Browns Creek is
protected to the same or higher level as in the AUAR preferred option.
' Recommendation B: Evaluate and developstrategy to moth downstream channel below
g3' modify
' McKusick Lake to accommodate increased flows.
Rationale: The diversion will increase the peak flows, volumes, and duration of discharges
' released from McKusick Lake to the downstream ravine and conveyance system southeast of the
lake. While a detailed evaluation of this portion of the system was beyond the scope of this
' study, modification of the conveyance system below the lake will be needed to prevent erosion in
the ravine and rout the water safely through the City without raising the potential for flooding.
Recommendation 3: Construct detention basins in the watershed as development proceeds.
Rationale: Properly designed wet detention basins are among the most effective tools to reduce
' pollutant loadings from developed areas. These basins should be constructed by developers as
part of the cost of mitigating off-site impacts of each development. It is essential to try to assure
that jurisdictions throughout the watershed -both within and outside the City of Stillwater -utilize
' these practices to minimize the impacts of development on downstream resources.
Lake Assessment and Action Plan for McKusick Lake

Recommendation 4: Improve the fishery and provide public access. This should include
adoption of a City ordinance to prohibit use of gasoline motors on McKusick Lake,
installation of a public canoe landing at the existing park area on the southeast corner of
the lake, construction of a fishing pier, stocking of gamefish, installation of a winter
aeration system (if needed). Consider development of trails that will connect McKusick
Lake area with other parts of the City.
Rationale: Riparian landowners have expressed to the City a desire to at least maintain the
recreational suitability of McKusick Lake in the future. This option has the potential to enhance
the recreational value of the lake. Any commitment of state resources to assist in this
management effort is, however, contingent on installation of a public access that would allow the
public to use the lake for the same recreational purposes as riparian owners.
Recommendation 5: Improve shoreline management. At a minimum, the lake association
and the City should develop a shoreline management demonstration area along the
shoreline of the City -owned land near the lake outlet.
Rationale: The diversion will cause water levels in the lake to be higher and stay up longer in
response to runoff events than it has historically. This condition is likely to increase the potential
for shoreline erosion, especially in those areas where maintained turf grass extends down to the
shoreline. Operating the lake at a higher normal water elevation is likely to increase this
potential. One way of stabilizing shoreline areas is to establish a community of native long-
stemmed, deep rooted grasses that can withstand periodic inundation. Development of a
demonstration area on the lake would be a good way of promoting the benefits of such a practice
to shoreline owners.
Recommendation 6: The City, lakeshore, and watershed residents should adopt non-
structural methods of protecting water quality, such as improved street sweeping, public
education, etc.
Rationale: These practices are important because they are intended to reduce at the source the
pollutants that can degrade lake water quality and they are relatively inexpensive to carry out.
They are most effective when used in combination with other practices such as detention basins,
etc.

By: Sherri Buss, Bonestroo & Associates
' I. Introductions—Task Force and Project
Task Force members introduced themselves. Chuck requested that a list of members and
their phone numbers be provided to the group. This will be included in the mailing for
' the next meeting.
Sherri noted that the goals of the study are the following:
' • Identify and analyze the current status of the lake
• Identify and analyze changes that will occur with implementation of the
Stillwater GUAR and the diversion of stormwater to McKusick Lake
' • Identify actions that could be taken to maintain or improve the health of the
Lake, and analyze their likely costs and benefits
• Make a recommendation to the City Council regarding actions to be taken to
' protect or improve the status of the lake.
Chuck noted that the McKusick Lake Homeowners petitioned the City Council to
' complete this study to specifically examine issues related to the lake level. He indicated
that lake residents are opposed to returning the lake to its permitted water level.
(Background—the Normal Water Level of McKusick Lake was set at 852.3 feet in 1981
when the outlet was constructed at the east end of the lake. The average level of the lake
during the 1970's and 1980's was 851.8 feet, with a variation of about .5 feet. Around
1993 the level of the lake was raised to 853.5 feet, in violation of the DNR permit for the
lake.
The DNR has indicated that the lake level needs to be restored to the Normal Water
Level, 852.3 feet. The Stillwater AUAR proposed that the Normal Water Level for the
' lake be set at 852 feet, so that the lake could help to hold additional stormwater diverted
to protect Brown's Creek. The watershed modeling completed for the AUAR indicated
that during normal years, the actual operating level of the lake would be close to 853 feet,
' because it will take a week or more for stormwater from each storm event to flow from
the large watershed area and clear the constricted outlet at the east end of the lake. The
Lake Association favors keeping the lake at its current level, 853.5)
II. McKusick Lake Existing Conditions and Modeling
Rich Brasch summarized existing information available for Lake McKusick:
Depthprofile: about 80 percent
of the lake is five feet deep or less, based on information
gathered in a field survey from 10/15/98. There is one deep "hole" approximately 17 feet
deep. The depth profile will be important later in the study as we analyze water turnover
in the lake.
' Aquatic plant community (aquatic macrophytes): major plant species identified in the
field survey were coontail and water cabbage. No invasive exotic species such as
eurasian water milfoil, curly pond weed or purple loosestrife were found in the survey.
The lake clarity is approximately 3 feet, and plants usually grow out to approximately 2
times this depth. In McKusick major plant growth occurs out to a water depth of about 7
' feet. Most of the lake has a peat bottom.
Coontail is a valuable plant from a water quality perspective. It competes directly with
' algae for nutrients (such as phosphorus), so abundant coontail in the lake helps to reduce
potential algae populations. Aquatic plants help to stabilize the lake bottom and the
shoreline. Water cabbage is particularly valuable in providing fish habitat.
' As aquatic plants die and accumulate at the bottom, they accumulate at a rate of 3-15 mm
per year. This process occurs in all lakes. Lake residents noted that at times during the
summer, pondweed floats to the surface and mats move on the surface of the lake.
Water quality data: Water quality data collected by the Metropolitan Council indicates
' that McKusick lake has a rank of C/D for most years.
It is possible that if water quality improves, lake clarity will increase, and aquatic plants
' will colonize the lake to deeper levels.
Rich noted that during 1997, a very high precipitation year, the water clarity in McKusick
' Lake was substantially higher values in average years. This may indicate that a higher
level of flushing will help to improve lake quality. Rich reviewed similar lakes in Eagan
that may provide clues to how management actions may affect McKusick Lake. He
' noted similarities to Blackhawk Lake, which also has a large watershed and high amount
of phosphorus moving through the system. However, on this lake the high level of
flushing combined with aquatic plant harvesting have helped to maintain relatively high
' water quality.
Watershed conditions: The current watershed area for McKusick Lake is 1100 acres.
When the diversion strategy is implemented, the watershed will increase to
approximately 4600 acres, a watershedaake ratio of 80:1.
' Committee members discussed the watershed area and relationship of impervious surface
and land uses to water quality. Members noted the old city dump site southwest of the
lake that drains to it. This area is currently being studied to identify potential problems.
Members reviewed the diversion strategy proposed in the AUAR, and changes in water
movements proposed through McKusick Lake.
Rich described the modeling that will be completed for McKusick Lake, to assess the
' impacts of the diversion on lake water quality. The results of the modeling will be
available at the next meeting of the Task Force.
' Molly provided maps and fisheries data from 1958 and 1947. Duane Shodeen, Metro
DNR Fisheries, reviewed this data and suggested that it indicates that the water from
' Browns Creek flowing through McKusick Lake (before the current dike was constructed)
helped to aerate the lake and allow fish to survive the winter. The fisheries data may
indicate that aeration is a strategy that would improve the health of McKusick Lake and
' allow re-establishment of game fish populations.
III. Options for Lake Management
' Rich reviewed the options to be considered for lake management in this study:
Dredging
Plant community and shoreline management
' Selective harvesting to manage aquatic plants
Temporary winter water level drawdown to manage aquatic plants
Improvement of the fishery
' Aeration of the wetland above the lake to improve water quality
Raising the control water elevation of the lake (including looking
At changes to the outlet at the east end of the lake)
' Non-structural options to reduce pollutant loading
Detention basin requirements in developing portions of the watershed
' Chuck suggested that a cost estimate for dredging the whole lake be obtained, as well as
for portions of the lake. Committee members agreed, but noted that the costs are likely to
be very high. Other options that are particularly important to the lake association
' members include raising the control water elevation and detention basin requirements.
Klayton asked the group to support a letter to the Minnesota DNR requesting a delay in
' returning the lake to its Normal Water Level until this study is completed (approximately
March, 1999). The DNR had sent a letter to the City in October requiring an immediate
return to the NWL. Task Force members supported a delay, so that the Task Force can
' complete its work and develop recommendations regarding lake levels and other
management options.
' IV. Next Meeting
' The Task Force set its next meeting for Tuesday, January 12, from 2 to 4 p.m. at
Stillwater City Hall. This will allow time to complete the watershed modelling, and for
analysis of the management options. These items will be the focus of the next meeting
' agenda. The meeting adjourned at 4:00 p.m.

Meeting Summary
Present: Jerry Fontaine, Stillwater Planning Commission; Barb Cobb,Middle St. Croix
WMO; Chuck Frederickson, Dick Jeans, McKusick Lake Association; Molly Shodeen,
' Mike Halvorsen, Minnesota DNR; Mark Doneux, Washington SWCD; Nancy Brown,
Stillwater Parks Commission; Rich Brasch, Mark Hanson, Bonestroo & Associates.
' By: Sherri Buss, Bonestroo & Associates
I. Background
' Sherri reviewed the storm
water diversion through McKusick Lake that was adopted as a
' part of the Stillwater AUAR. Under this strategy the proposed Ordinary High Water
Level for McKusick Lake was proposed to be 852'. (The DNB's permitted OHWL for
the lake is 852.2'. The current lake level is in violation of the permitted level, at 853.5'.)
II. New Option for McKusick Lake Level
Mark Hanson presented a new option for the storm water diversion that would allow the
OHWL to be set at 853'.
• This option includes increasing the existing dike to 856.5', maintaining the existing
' separation and variation in water levels between the lake and its wetland.
• The option would run storm water flows from the diversion through McKusick Lake
up to a 3", 5 -year storm event, protecting Browns Creek to the same degree as
' proposed in the AUAR diversion option.
• In larger storm events, some flow would be directed to the wetland. Additional
analysis is needed to determine the size of these flows.
• The current outlet at the east end of the lake would be maintained at 21 ".
• McKusick Lake would bounce approximately 3 feet during the 3" storm event.
' The Task Force members raised the following questions regarding the new option:
+ The degree of bounce during storm events is a concern, particularly for homes on the
' southeast part of the lake. The potential for flooding in this area should be
determined, and discussed with property owners. (The AUAR diversion option
proposed a 2.5' bounce starting from a lake level at 852'; this option includes a 3'
bounce from a normal water level of 853'.)
Members asked about the current bounce on the lake during storm events. The
' bounce is currently about 1 to 1.5'.
n
L
r
• The bounce may also be a concern for wildlife habitat. DNR Wildlife staff are
concerned about a 3 -foot bounce during a 100 -year event, and may be more
concerned about this occurring more frequently.
However, this option protects the habitat values of the wetland to the north of the lake
to a greater degree than does the AUAR diversion option. The wetland provides a
greater diversity and higher quality of habitat than the lake. The whole set of
tradeoffs with other options should be evaluated.
• If the City determines that this option is feasible, and wishes to request that the
OHWL of the lake be changed to 853'', it will need signed agreements from each of
the landowners around the lake that they are willing to donate the shoreland to allow
the lake level to rise. The DNR and City should determine whether an easement is
needed to the Ordinary High Water Level, or the High Water Level during 100 year
storm events. All landowners will need to agree to donate the easement for this
option to be feasible.
DNR staff from Fish, Wildlife, and Waters divisions need to determine the
acceptability of this option, and whether the agency agrees that it provides the same
level of protection to Brown's Creek as the AUAR. Potential changes to the wetland
under the AUAR diversion option were a DNR concern --the new option has
advantages because it causes less change in wetland communities.
• Members asked whether outflow from the lake could be increased to decrease the
potential bounce. The model for this option was run with an increase in outlet size
from 21" (current) to 27", but this did not affect the bounce. This issue will be
examined further.
Task Force members agreed that the option is an interesting one, and that additional work
should be completed on issues identified above.
' III. Water Quality Issues
Rich Brasch discussed his work since the last meeting to identify a lake water quality
' model that fits McKusick Lake. A model with good reliability has been identified, and
has been run for the current situation, AUAR diversion, and New option (described
above).
' The model indicates the following:
• in -lake phosphorus levels after either of the diversion options will be within the range
that the lake has experienced under current conditions:
' • the flushing time for the lake will be dramatically reduced when a diversion is
implemented, and this will counter the additional phosphorus that will be transported
' to the lake with additional storm water;
C
L
• additional ponding in the annexation area and in City of Grant will help to reduce the
phosphorus loads to McKusick Lake.
IV. Options for Lake Management
The Task Force will discuss the nine options for lake management outlined in the packet
at its next meeting.
Klayton Eckles suggested that the costs for dredging assumed in the options is too low—
the
owthe City will need to transport the material away from the lake, and this will add costs.
V. Next Meeting
The Task Force will meet on Thursday, January 28, from 2 to 4 p.m. at Stillwater City
Hall. The agenda will focus on the options for lake management, and any additional
information on diversion options.
Public Meetings. The work plan for the study indicates that the City will hold two
public meetings to discuss the work of the Task Force. The Task Force recommended
that the first of these be held during February, so that lake residents and others can
comment on the options the Task Force is considering. The final meeting will be held at
the end of the study to report the Task Force recommendations.
The Task Force adjourned at 4 p.m.

--McKusick Lake Task Force
January 28, 1999
Stillwater City Hall
Meeting Summary
Present: Nancy Brown, Stillwater Parks Commission; Mike Halvorson, Molly Shodeen,
Minnesota DNR; Dick Jeans, Chuck Frederickson, McKusick Lake Association; Jerry
Fontaine, Stillwater Planning Commission; Klayton Eckles, Stillwater Public Works,
Rich Brasch, Sherri Buss, Bonestroo & Associates.
I. New Lake Management Alternative—Further Analysis
Rich Brasch of Bonestroo & Associates summarized the alternative management strategy
presented at the earlier Task Force meeting in January. Rich noted that the alternative
has been modified to allow a minimum flow (1.5 cfs) to either the McKusick wetland or
Brown's Creek. Modelling of this modification indicates that the "bounce" in McKusick
Lake during storm events will be reduced to 1.8 to 2.3 feet, depending on the size of the
event. Sherri noted that bypassing the flow to the wetland will be desirable to sustain the
current conditions and communities in the wetland.
Rich provided a summary of the new management option, and its conditions during 5 -
year and 100 -year storm events.
• Chuck Frederickson asked if increasing the size of the pipe at the McKusick Lake
outlet would help to reduce the bounce during storm events. Rich noted that the
engineers have indicated that this will not have much effect on the bounce, and may
have negative effects on the ravine downstream from the lake. Chuck indicated that
this will probably be a question at the public meeting, and a clear explanation should
be provided to area residents.
• Molly Shodeen noted that the DNR favors adequate detention time in McKusick Lake
and upstream to remove phosphorus before storm water enters the St. Croix River.
• Jerry Fontaine asked if additional ponding is possible in the ravine downstream from
McKusick. Klayton indicated that the narrowness, steepness, and grades in the ravine
make this unlikely.
• Rich noted that the elevation at the top of the existing McKusick Lake outlet is
855.3'. This is the level the lake would reach in a 100 year storm event under the
new management option. City of Stillwater staff will be surveying the elevations of
existing home on the southeast part of the lake (lowest home elevations around the
lake). Information on how the new option and project bounce will affect these
properties will be available at the public meeting.
• Rich reviewed the cost estimates for implementing the new option in comparison to
those calcuated for the AUAR, (Those for the new option are more preliminary than
those available for the AUAR.) The estimates indicate that the new option will cost
about the same or less than the AUAR option.
0
' • Chuck Frederickson noted that if new material is added to the dike, it could affect the
depth of the lake near the dike, which is already shallow. He suggested that
' homeowners in this area may request that dredging occur along the dike if this is
proposed. Rich indicated that there may be negative aspects of dredging in this area.
The emergent vegetation there provides good habitat, and will help to protect the lake
from sedimentation if new material is added to the dike.
• Molly Shodeen provided high-quality aerial photos of the wetland along its western
boundary. The photos indicate areas where water moves across the existing spoil
' areas along the shoreline, and that the southwestern portion of the wetland is much
wetter than other areas.
' • Rich noted that the costs shown do not indicate costs for developing a trail along the
west side of the wetland, but are minimums for evaluating this option.
• Jerry Fontaine asked if neighbors along the ravine south of McKusick Lake will be
' notified of the public meeting, if changes are contemplated as a part of implementing
the new management option. Klayton indicated that potential changes in the ravine
are so tentative that it is not necessary to notify ravine neighbors at this time.
' • Molly noted that the process for changing the Normal Water Level of McKusick Lake
to 853 ° will include the following. The City needs to apply to the DNR to amend its
current permit and change the lake level. She indicated that the Wildlife and
Fisheries Divisions have indicated that they do not see a problem with allowing this
change.
' In order to apply for the amended permit, the City of Stillwater will require that each
resident along the Lakeshore be willing to donate an easement to the City up to the
100 year high water level, so that the new level is not a "taking" of private property.
The City will probably not be willing to purchase easements from Lakeshore residents.
This information will be presented to Lakeshore residents at the public meeting.
' II. Options for Water Quality Management
Task Force members reviewed the eight options proposed at the last meeting that may
help to improve water quality in McKusick Lake. They determined that the following
should be recommended to the City as feasible and beneficial:
' #1 Construction of detention basins in the watershed with new development
#4 Improvement of the fishery and public access
• Develop a public canoe landing at the existing park area. The City could
seek funding from the DNR to develop a public access.
• Develop a kids fishing pier, and stock the lake to provide fishing
opportunities. (DNR funds may also be available to develop a fishing pier.)
• The City should adopt an ordinance prohibiting the use of gasoline motors,
including jet skiis, on McKusick Lake
' • The City should work with the DNR to determine whether an aeration
system is needed on the lake to support a sport fishery.
'�J
FSI
#7 The Lake Association and City should develop a Shoreline Management
demonstration area along the shoreline of the park near the lake outlet. Funding
to assist with a demonstration project may be available from the DNR.
#8 The City, lakeshore and watershed residents should adopt nonstructural (also
called "housekeeping") methods such as improved street sweeping, public
education, etc. to improve lake quality.
The other four options were discussed. The Task Force determined the following:
#2 Modification of the wetland above McKusick Lake. This option is not applicable
under the new option that keeps the wetland and lake at different levels.
#3 Dredging. This option is not needed if the lake level is maintained at 853' under
the new option.
#5 Mechanical harvesting to manage weeds. This option may not be needed if the
lake level is maintained at 853' under the new option. Could be considered later
if plant growth becomes a serious problem.
#6 Temporary water level drawdown to control weeds. This option may not be
needed if the lake level is maintained at 853' under the new option. Could be
considered later if weed growth becomes a serious problem.

IV. Questions and Comments
Audience
Summary of Responses to Questions By Attendees
McKusick Lake Public Meeting
' February 25, 1999
1. Why not just put in a bigger pipe, so you could gust leave the wetland alone?
' A bigger pipe is part of the new proposed management strategy for McKusick Lake.
Under the proposed recommendation, the existing outlet capacity would likely be
expanded to reduce the bounce in McKusick Lake for storm events. Some modification
' of the system that takes McKusick Lake discharge through downtown Stillwater will be
needed to accommodate the additional flows associated with both the diversion and the
outlet enlargement. However, the conveyance system improvements necessary to carry
' all flow from large runoff events would likely be prohibitively expensive. Further, they
appear unnecessary since discharge of additional stormwater from larger events over the
proposed spillway at the north end of the lake to Brown's Greek will be sufficiently
1 infrequent so that the trout population is impacted no more than under the AUAR
preferred option.
' 2. What was the phosphorus level before the City began pumping from Lily Lake?
You use the word "historically" to talk about the last five years (the years for
which you have records). That is not very historic.
Good data for water quality is only available since 1994 for McKusick Lake and since
1995 for Lily Lake. The lift station that periodically discharges Lily Lake water to
McKusick Lake was installed in the early 1980's. Thus, water quality information prior
to the installation of the lift station is not available. Data that is available indicates that
water quality in Lily Lake is generally better than that in McKusick Lake. Thus,
incoming water from Lily Lake should have no adverse impact on water quality in
McKusick Lake.
3. Do the treatment options you're proposing for McKusick take into consideration
the proposed treatment at Lily Lake?
The treatment options for Lily Lake would all be aimed at improving water quality in
Lily Lake, which should result in better quality discharges to McKusick Lake. However,
the impact of these discharges will be negligible because of the volume of water coming
into McKusick Lake from other sources after the diversion is constructed. By far the
biggest impact on water quality in McKusick Lake will be the quality of the large amount
of water corning from the diversion above the lake.
4. We're getting all this water from the annexation area. I know where it surfaces
downtown on Second Street. What if it rains 8 inches?—It won't fit.
The proposed plan includes a recommendation to improve the conveyance system
downstream of McKusick Lake. These improvements would be made after a more
' detailed evaluation of the downstream system. It is important to remember thaiority --
runoff from a 3.5 inch (5 -year) storm need be accommodated by the downstream system.
' The additional runoff from larger events will be discharged to the north wetland and into
Brown's Creek.
1 5. Is the proposed stream restoration actually going to take place?
Yes. MnDNR fisheries staff are working on final designs for a restored stream channel
' on Brown's Creek.
6. Why did you go from 853.4 to 853 (normal water level since 1993 vs. the
' proposed new normal water level). You're giving up a half a foot. Why can't we
go to 853-112?
n
r
7
A normal water level of 853 for McKusick Lake was considered by the task force as the
best compromise between maintaining a higher normal water level in the lake and
minimizing the potential for flood impacts around the lake under post -diversion
conditions. For reference purposes, the water level in the lake last October was about
852.7.
7. Why did the City issue a building permit that resulted in a basement being at an
elevation of 861.3 (basement floor elevation of 854.8)—the lowest on the lake?
Why should everyone else have to accommodate this (as a constraint to
maintaining a higher NWL in the lake)?
Whatever the reason for the decision, it is something we have to live with and view as a
legitimate constraint on how high the lake water level can be raised. Given the normal
water levels of the lake in the past (851.5-852.3), the decision to allow construction of
this home doesn't seem particularly unreasonable.
8. The deep spot in the lake used to be deeper -21 feet. It supported many fish.
There never used to be winterkill. Why is there winter kill now?
Historical observations by fisheries experts and residents indicate that the connection
between the lake and the north wetland apparently allowed fish to enter the spring areas
in the north wetland and even Brown's Creek itself to overwinter. A decrease in the
maximum depth of the lake from 21 feet to 15-16 feet currently is unlikely by itself to
have much impact on the winterkill potential.
9. By not having Brown's Creek run through wetlands first, will the water quality
turn yucky? Are there springs?
There appears to be significant spring discharge to the wetland both above and below the
point at which the diversion water would be introduced to McKusick Lake. Hopefully,
spring discharges will help to sustain the wetland in near its present condition. Keeping
McKusick Lake at a higher level than the wetland means that the option to direct the
' diversion flow to the wetland for additional treatment is no longer available. Under -these
conditions, it becomes even more important to create water quality treatment ponds in the
' upper watershed to reduce pollutant levels in the incoming water to McKusick Lake.
10. With increased flow, what is the effect on vegetation, water temperature and
' depth on the lake?
Vegetation: If the nutrient concentration of the water increases, aquatic vegetation could
increase. However, water quality modeling indicates that nutrient concentrations after
the diversion should be at the upper end of the historical range experienced before the
diversion. Thus, water quality as evidenced by water clarity should be about the same as
' it has been historically.
Water temperature: We don't expect the water temperature to change from the fairly
warm conditions in existence today.
' Lake depth: Like all lakes, McKusick Lake will gradually fill in over time due to residue
from decaying plant matter, etc. The trick is to slow this process to the extent possible by
making sure eroded sediment from construction doesn't reach the lake and by minimizing
1 the amount of phosphorus that reaches the lake to feed excessive aquatic plant growth.
11. If there is a 1% chance annually for the storm even you describe (100 -year
' storm) how long would the water level be at 855 feet? I am concerned about
capillary action. My basement is at 857. Is it safe? What's the likelihood of
getting flooded?
It could remain at that level for about two weeks. Capillary action would likely take
' longer than that to reach it's full extent.
12. What controls the flow of water into the pipe that goes to the St. Croix?
' The main controls on the amount of water are the elevation of the lake relative to the
outlet pipe and crest of the proposed spillway to the north wetland, the size of the outlet
pipe, and the slope of the outlet pipe. At present there is a 21 -inch outlet pipe from
McKusick Lake that discharges to combination of open channel and pipes that carry the
flow through downtown. While a more detailed look needs to be taken at the work
required to improve this system, the preliminary estimate for the work is $350,000 to
$450,000.
13. Explain the bounce in McKusick Lake and the volume and rate of flow out of the
lake.
' A storm event will generate runoff that will cause a temporary rise in the level of the lake
before all the water from the event is discharged through the outlet(s). The bigger the
' storm event, the higher the maximum elevation to which this water level will rise. The
objective of the task force was to keep the maximum water level in McKusick Lake from
rising no more than 2 feet for a 5 -year storm (3.5 inches in 24 hours) and no more than 3
1
i
L
feet from a 100 -year storm (6 inches in 24 hours). Enlargement of the outlet pipe and -
adjustment of the elevation of the spillway to the north wetland will be necessary to meet
these goals, but computer modeling indicates that they can be met.
14. When would the bypass occur? Should there be an emergency structure to flood
the wetland before the lake would flood in a catastrophic event?
With the proposed spillway, lake water would be discharged into the north wetland to
minimize the rise in the flood stage of the lake. As per the requirements outline in the
AUAR, bypass of flood discharges to the north wetland from the lake would occur only
for storms greater than a 5 -year event (3.5 inches in 24 hrs.).
15. What is the elevation of the wetland, lake and channel?
The elevation of the wetland ranges from about 856 at it's northwest corner to 851 at it's
northeast corner. The proposed NWL of the lake is 853. The channel elevation just
above the lake is 854.
16. Does the dike (at the north end of the wetland under the preferred AUAR
option) have to get built?
Under the new option being proposed by the McKusick Lake task force, the dike at the
north end of the wetland would not be constructed. Instead, the existing dike between the
north wetland and the lake would be raised slightly.
17. Doesn't the stormwater utility fee that we pay cover all the costs for the
improvements?
No. That fee covers maintenance items, such as street sweeping in the Lily Lake
drainage. In the future, the funds will likely support similar activities in the McKusick
Lake watershed. Charges to developers will pay for most of the capital costs of the
proposed improvements.
18. What is the next step?
A final report on recommendations from the task force will be presented to the City
Council in April 1999. If the Council concurs with the recommendations, a permit
application to raise the normal operating level of the lake to 853 would be submitted to
the MnDNR. The process of securing donations of easements from shoreline owners will
also begin.
19. What if one person says no to the easement (required to raise the permitted
NWL to 853)?
It is likely that MnDNR will require easements from 100 percent of the lakefront property
owners before it actually approves issuance of a permit for the higher water level. The
' City will have to decide its course of action, but it is highly unlikely that the City would
agree to purchase any easements. The City will likely look to the McKusick Lake
' Association to exercise leadership on this issue, since the shoreline owners have
expressed a strong desire to raise the permitted elevation of the lake.
I20. What are the funding issues? Where does the money come from to pay for the
improvements? What is the timeline?
' New developments in the watershed contribute to a fund to finance construction of these
improvements. An estimated $3.5 million is expected to be raised from development
funds. City staff is exploring funding options including state funds and cost sharing with
' Browm's Creek Watershed and the City of Oak Park Heights.
The City expects to begin design this summer. The best case is that construction would
' begin in two years and the worst case, in five years.

Meeting Summary
' PRESENT: Chuck Frederickson, John Baird, McKusick Lake Association, Jerry
Fontaine, Stillwater Planning Commission; Klayton Eckles, City of Stillwater; Molly
Shodeen, Mike Halvorsen, Minnesota DNR; Nancy Brown, Stillwater Parks
' Commission; Rich Brasch, Bonestroo & Associates.
By: Sherri Buss. Bonestroo & Associates
' I. Review Comments from Public Meeting
' Task Force members reviewed a summary of the comments and questions from the
Public Meeting held on February 25. Twenty-two people attended the public meeting.
Members concluded that those who attended the meeting were in favor of the new lake
' management option (with a normal lake level of 853') and the water quality improvement
strategies recommended by the Task Force.
' DNR staff noted that remaining concerns include the effect of the new option on Brown's
Creek and on the ravine downstream from McKusick Lake. Bonestroo staff indicated
that modeling has been completed that shows that the new option will have the same or
an improved result for Brown's Creek in comparison with the option proposed under the
Stillwater AUAR. City staff are recommending that some additional work be completed
to detail the effect of additional flows in the ravine, and develop recommendations to
' protect the ravine and downstream conveyance system.
II. Final Review of Lake Management Recommendations for Presentation to the
' City Council
Members reviewed the recommendations, and made no changes. The recommendations
' will be presented to the Stillwater City Council at their first meeting in April, along with
the modeling results and recommendations for further study of the ravine and
downstream system.
III. Next Steps
' If the City Council adopts the recommendations of the Task Force, the Council will then
ask that lakeshore each land owner around McKusick Lake agree to donate an easement
up to the new high water level.
' Task Force members suggested that the City should provide some stakes along the
shoreline to show residents the new high water level, and suggested easements. The City
' should also inform residents about what is allowed within the easement.
1 _
1 If easements are donated by all lakeshore owners, the City will request that the DNR raise
the normal water level of McKusick Lake to 853 feet.
1 Task Force members also suggested that their recommendations regarding restrictions on
motorized boat traffic and development of a canoe access on McKusick Lake be referred
to appropriate city commissions, such as the Planning Commission or Parks Commission.
1 This suggestion could be included in the recommendation to the City Council
1 Members requested that they be notified of the City Council meeting that will include the
review of the Task Force report.
