spoke briefly introducing the
Chair Fischer said he would address the minutes from the January 7, 2009 meeting and go through them
page by page for corrections. He had two corrections: A sentence read "...currently most trails begin at
one point and end at another". He corrected this sentence to say "....currently most trails begin at one point
and end at another; "what are the best practices" should be added. (page three)
Commissioner Sonnek referred to the sentence "...how research on community gardens was done"; she
believed she had said how research "in general" was done, and "dog parks" should be added with "research
on community gardens". (page two)

Chair Fischer said there was a sentence involving discussion about basketball hoops taken up or down. He
said the sentence should read "Edgerton School staff could perform this task of lowering and putting up
hoops if we decide to resolve it in this way". (page four)
Commissioner Brannon said a sentence stated" the staff should not deal with policy issues; it should read
"the staff should deal with policy issues". (page five)
Chair Fischer referred to the sentence "...there are conservation easements in the preserves right now. He
had meant to say that "...there are no conservation easements in the preserves". Also, the sentence
"Presence of these preserves on the farm land would force a 4-1 vote for the protection". This sentence
should read "...would force a 4-1 vote to take away the protection". Commis' .er Brannon said the date
that the Hazelwood Park plan was developed (turf management plan) was' page six)

1. South on MCKnight~Qadand east on Lydia Avenue;
2. Through the power Line easement between County Road D and Lydia Avenue;
3. East on County Road D, and south on Bellaire tying into a segment of trail which was buiit as a part of
recent improvements at Joy Park.
Mr. Horn said another scenario is constructing the trail east on County Road D, south on Bellaire Avenue
and east on Woodlyn Avenue, and through the Joy Park Open Space property. He said they had discussed
how to best make the crossing at McKnight Avenue, such as pedestrian signals and special treatments
within the pavements. Ultimately, the traii along County Road D would have to be coordinated with street
reconstruction, which will most likely occur in 2012. Because of potential funding, city staff was exploring
the possibility of the County Road D project occurring in 2009. He said there will be a neighborhood meeting
2
regarding this on February 19, 2008. There is a possibility that the coordination of County Road D and the
segment of the trail on County Road D could be accelerated and occur along with the street reconstruction.
The alignment through the Joy Park Open Space presents challenges; steep grades, vegetation, wetland
areas, and frequently used worn traiis. They looked at site lines at various locations and have identified
the best location. He also gave the current cost estimates:
Option A, Lydia Avenue alignment, is the least expensive with least construction costs: $240,000.
Option B, alignment along County D that connects along Bellaire Avenue; approximately $325,000.
There would be additional cost if the traii would go through the open space, which would be
$450,000. This option is advantageous because the trail could be constructed at the same time as
the County Road D reconstruction, which would result in cost savings.
Option C is the most expensive through the power line easement, an.clUJ was decided that this
option be dropped.
He then took questions from the commission.

Open Space Coordinator Gaynor saidwl1en the Master Plan for Joy Park was developed it was difficult to
develop because of all the issues with this park. Tl1ey were very clear in the Master Plan that they would
have no paved trails on the north side of the road. She said they would like to respect that decision.

Commissioner Fischer said they should focus on the Joy Park link first and then with County Road D versus
Lydia Avenue.
Commissioner Brannon suggested they have a vote or show of hands about the segment continuing
through the north of Joy Park. The consensus was that they would drop the option through Joy Park. The
other options remaining were County Road D versus the Lydia Avenue option.
Staff Director Konewko stated the other two options are County Road D east to Bellaire Avenue going
south, or south on McKnight Avenue joining with Lydia Avenue, east on Lydia Avenue and connecting with
the trail already constructed. He said they have had meetings with Lydia Avenue residents and the people
that live in the Bellaire Avenue and Lake Street area were also included in that distribution list. He said staff
is looking for direction so they can work with John Horn to finish this project.

Commissioner Sonnek asked if they could have an itemized list and a summary prepared of directly
impacted resident numbers for each plan, and Commissioner Brannon said he would also like to see a
summary of this project so they can come to a decision. Commissioner Peterson would also like to see a list
of safety concerns for each option.
Chair Fischer then asked neighbors to add or comment on the discussion.
Lori Johnson, resident on Lydia Avenue, spoke about the importance of the natural area on the north side of
Joy Park. She said it is an area that the neighborhood uses frequently, and it was a much appreciated area.

meetings through August or September, 2009. The meetings will be held the first Wednesday of every
month. They would like to start touring possible sites in May.
Commissioner Roman said the University of Minnesota study showed there was interest in having a dog
park in Maplewood, and the subcommittee will gather more information about dog parks, including specific
sites, pros and cons of having a dog park, talking with businesses in the area such as PetsSmart@,
regarding contributing to or funding a dog park. They talked about amenities that would be preferred in a
park, such as benches, water to play in, covered plastic barrels, shade, and jumping areas. They also talked
about a dog park in Maplewood possibly being unique, trying to make it different than anywhere else.

He said their next meeting is Wednesday, March 4th at 7:00 p.m. Commissioner Roman asked if there was
anyone else on the commission that would like to serve on the subcommittee. Chair Fischer said if there is
a fourth person interested, it would be acceptable to add another person.
Commissioner Maas asked about lighting for a dog park. He said there is a dog park on Lake St. in
Minneapolis, and the lighting is very extensive, lighting up the entire area. Commissioner Schmidt said
there is lighting they could use that is more down-cast in nature.
Commissioner Schmidt asked if they were planning on serving just the city of Maplewood; if the park was
really unique and unusual, it would draw people from all over the area. They qj~cussed how they were
going to have people share costs if they traveled from other areas.

Stormwater Management Impacts at Spoon Lake Preserve and
Kohlman Park

SUBJECT:
INTRODUCTION
City staff is requesting input from the Parks Commission regarding the proposed storm water
management features on the Carsgrove Area Streets project (Attachment 1). This item was
brought before the Parks Commission on March 18, 2009. It was clear to city staff that this item
required more time to be reviewed by the Environmental and Natural Resources Commission
(ENRC) prior to be brought before the Parks Commission again.
Staff revised the project schedule and brought this item before the ENRC on April?, 2009. The
ENRC voted to approve the general design concept. The landscape designs will be brought
before the ENRC to be reviewed and incorporate comments before being approved. The project
is scheduled to go before the City Council on April 2?, 2009 for approval.
Staff has taken steps to make sure that on all future projects adjacent to or impacting open space
or parklands will be brought to the ENRC and the Parks Commission at the beginning of the
project in order to receive and incorporate valuable input and ideas from the commissions.
DISCUSSION
Stormwater Management Proposal
The current drainage system in the Carsgrove neighborhood provides little to no treatment of
stormwater, so any treatment created.as part of this project will result in an improved quality of the
runoff waters to Kohlman, Gervais Lakes, and surrounding wetlands. The city's plan is to install
two large filtration basins on this project to provide treatment of water and meet volume reduction
requirements-one at the northern entrance to Spoon Lake Neighborhood Preserve (south end of
Forest Street) (Attachment 2), and the other at Kohlman Park (intersection of Cypress Street and
County Road C) (Attachment 3). Individual rain gardens will be offered to residents to help
provide additional treatment.
Kohlman Park
On the Carsgrove project, the Engineering Department is proposing a filtration basin at the
intersection of Cypress Street and County Road C, at the northwest corner of Kohlman Park. The
proposed basin would lie between the roads and the existing basketball court and parking lot. A
rain garden was constructed in this area in 2001 and planted by neighbors. The soils do not
allow water to infiltrate at a rate that typical rain gardens require. This has caused water to pool in
the rain garden killing many of the original plants. Cattails have taken over the wettest parts of
the garden. Rain gardens are typically designed to capture and treat the first flush of stormwater
runoff by infiltration. The current rain garden is working more as a flow through with a permanent
shallow pool of water.
The proposed basin would remove and replace the existing rain garden with a filtration basin.
The location was chosen due to grade limitations and the existing drainage patterns. The runoff
flows north along Cypress Street from the intersection with Connor Avenue to a low point at the
intersection with Knollwood Drive. Drainage from Knollwood Drive also is collected at this low
point. The runoff is then discharged to the existing rain garden and flows into the ditch along
County Road C.
Proposed Basin at Spoon Lake Preserve
The Engineering Department is also proposing to construct a filtration basin at the south end of
Forest Street in the Spoon Lake Neighborhood Preserve to treat water from Brooks Court and a
portion of Forest Street. Spoon Lake Preserve is an approximately 27.55-acre natural area
(Attachment 4). The proposed basin would require removing trees and grading approximately 0.5
acres located at the south end of Forest Street. According to the site analysis for Spoon lake
Preserve conducted by Barr Engineering in 1999 (Attachment 5), the site is severely degraded
ecologically and the native plant communities have been nearly completely destroyed.
An Interim Management Plan (Attachment 6) was adopted for the Spoon lake Preserve on
November 1, 2000, and included the following items:
1) The Soil and Water section calls for addressing the erosion and storm water coming
in from Forest Street and concerns that that this flow could run into the high quality
wetland located west of Forest Street.
2) The Neighbors and Community section calls for the posting of No Dumping
Yardwaste signs at the entrance near Forest Street since dumping has been a
problem at this entrance.
3) The Pilot Restoration Projects section calls for stormwater management and erosion.
Staff has been working with RWMWD to come up with an innovative basin design to fit in with the
natural aspects of the preserve, meet goals as set forth in the Interim Management Plan, and
enhance the residential entrance to the preserve.
Enhancements
Rain gardens and infiltration basins have been amenities at other sites because they add diverse
native plants to our parks and preserves.
Staff is working with Virginia Gaynor, City Open Space Naturalist, on the development of a
landscaping plan for the Kohlman Park basin that would include seeding, the planting of trees,
shrubs, and various plants.
Staff is recommending the following items for the Spoon lake Preserve basin:
1. Incorporate the storm basin into the preserve by planting it as a native plant community.
2. In addition to seeding the basin, plant trees, shrubs, and herbaceous plants in the basin.
3. Hire a landscape designer to develop a design for the Forest Street entry that fits in with the
natural character of the site.
4. Re-do the northern entry to the preserve.
5. Explore design concepts and innovative strategies to get the water from the street into the
basin.
6. Install 230 feet of graded soft-surface trail to connect the entry to existing footpaths on the
site.
7. Fix the existing stormwater erosion at the south end of Forest Street in the preserve.
RECOMMENDATION
Staff recommends to incorporate the proposed basins into the Carsgrove Area Streets project and
requests the commissioners to discuss the proposed filtration basin for the Kohlman Park and the
Spoon Lake Neighborhood Preserve and make a recommendation on how to proceed.

The following goals and tasks are recommended management practices to maintain the site until
long-term restoration goals are funded and implemented.
GOALS
:.,~
1. Ensure that the preserve is a safe, accessible site open to hiking.
2. Prevent spread of spotted knapweed.
3. Prevent invasion by purple loosestrifu.
4. Remove fruiting buckthorn trees.
TASKS
The starred items below are deemed essential
Safety, Access, and Amenities
."
-,
* 1. Preserve signs. Neighborhood Preserve signs should be installed on Keller Parkway and on
Forest Street.
2. Bike and vehicle nse. Vehicle and bike use should be monitored and addressed before it
becomes a problem.
3. Parking. Parking at the Spoon Lake parking lot is currently adequate and a cross-walk is
not necessary at this time. Limited street parking is also available on Forest.
4. Crime. There have been no reports of crime on this site.
5. Trails. There are foot trails on this site. It would be nice to clear :fallen trees and brush to
make a full loop trail. Once trails are cleared, periodic mowing or brush cutting would help
keep them open.
.6. Trash. Remove furniture, trash, and litter from site.
.7. Tree Fort. The tree fort on the site should be removed.
8. Fence. There is a barbwire fence on the interior which should be removed. A fence along
Keller Parkway should also be removed but this is low priority.

Vegetation Management
':i
',j
:':
* 1. Spotted knapweed is minimal but it should be pulled.
*2. Prevent entry of purple loosestife. Begin by removing plant on island and making certain
someone has released beetles in the wetland north ofthe preserve.
3. The site has severe infestations of buckthorn and anmr maple. Because these stands are
dense and the soils are primarily fine sandy 10ams, erosion could be a serious problem if all
exotic shrubs are removed and nothing is planted in their place. It is recommended that
buckthorn and amur maple not be eradicated until we have a plan for revegetation and a
neighborhood volnnteer force committed to long-term buckthorn management at this
preserve. If neighbors are anxious to begin buckthorn management, it would be fine to
remove the fruiting buckthorn without revegetating.
;~
:j
..
f;
;',
Soli and Water
* 1. Erosion. Address erosion and storm water corning in from Forest. This flow may be
running into the high quality wetland west of the site.
Neighbors and Community
*1. Address encroachment by neighbors.
1) Send letter to all adjacent landowners.
2) Follow-up with phone calls, tour, or home visits if necessary.
*2. Post no dumping yardwaste signs at entrance near Forest.
Wildlife
i~
1. Cooperate with Ramsey County Parks in controlling deer populations.
:!
~
Pilot Restoration Projects
~:
.:.
1. Storm-water management and erosion.
2. Yard waste management. Develop \ trials that include methods for neighbors to initiate on
their land as well as use of yard waste on open space sites.

THOUGHTS ON LONG-TERM RESTORATION AND MANAGEMENT

This section contains notes and preliminary thoughts abont restoration.
Also see recommendations in the site analysis done by Fred Rozuma1ski, Barr Engineering.

Thoughts Regarding Long-term Restoration
,:,;
\;1
This site is exlremely degraded and will be extremely difficuh to restore. Restoration may
prove unfeasible and should not be undertaken until we are convinced we have a good chance of
succeeding. Neighbors love this preserve. We need to bigblight what is best about it and be open
to alternative approaches to tbis site.
:j,
Task Force members have suggested the following target plant communities: big woods tor
southeast, floodplain forest in south cenlral, savanna on western slope (currently amur maple).
They disagree with Fred's assessment that the area of organic soils were disturbed mechanically.
A more detailed analysis and history is necessary to understand the soils and hydrology on the
site. A soil core might help us understand if there has been mixing of soil horizons. Pnblic works
should have some maps of runoff.
;;
t~
Because exotic trees are so dense, Task Force suggest girdling of large buckthorn to kill it
slowly until we can revegetate.

Silver Lake Improvement Association Request for Herbicide Treatment Funding
for Silver Lake
April 2, 2009 .
TO:
FROM:
SUBJECT:
INTRODUCTION
Silver Lake is located on the far northeast section of the City of Maplewood and shares its
border with two other municipalities, North St. Paul and Oakdale (Attachment 1). Silver Lake is
located in the Valley Branch Watershed District. The size of the lake is approximately 72 acres
with a mean depth of 7.3 feet, and a maximum depth of approximately 23 feet. A total of 35
residents and two parks have shoreline on the lake. The parks are Silver Lake Park in North St.
Paul and Joy Park in Maplewood.
The Silver Lake Improvement Association (hereinafter the "association") was created to help
restore Silver Lake. The association, made up of residents on or near the lake, has obtained
yearly study grants from the Minnesota Department of Natural Resources (DNR) for the
treatment of the lake with herbicide for the control of curlyleaf pondweed and Eurasian
watermilfoil starting in 2006. The total cost for treatment of the lake in 2007 was $40,000,
$60,000 in 2008, and is estimated to cost $36,332 this year. The DNR is offering another Total
Lake Treatment Pilot Study Grant for 2009.
The association estimates that Joy Park encompasses 33 percent of the linear shoreline of
Silver Lake. As such, Dr. Mike Manthei, president of the association, has submitted a letter
requesting that Maplewood contrib'ute 33 percent of the funding ($11,990) to treat the lake this
year (Attachment 2). The association is committed to a five to ten-year plan to restore the lake,
and as such is requesting yearly participation from the city.
BACKGROUND
June 23, 2008, the city council approved funding $8,250 toward the 2008 herbicide treatment of
Silver Lake (Attachment 3). The funding was authorized for one year on the condition that
future funds are authorized based on the results of additional lake studies and on the condition
that the association implements stormwater best management practices.
April 7, 2009, the Environmental and Natural Resources Commission reviewed the 2009
request for funding. The commission recommended approval of the funding, with one
commissioner voting against the request.
DISCUSSION
Herbicide Treatment
The cost of the 2009 herbicide treatment is estimated at $36,332. The treatment will include an
early-season application of Aquathrol K for the treatment of curlyleaf pondweed only. The DNR
1
does not recommend treating for Eurasian watermilfoil this year due to the decrease in some of
the native aquatic plants and a decrease in water clarity. The rationale for this approach is that
early-season control of curly-leaf pondweed may benefit water quality and is unlikely to
extensively reduce in native vegetation. On the other hand, lake-wide control of Eurasian
watermilfoil is unlikely to benefit water quality and may reduce native vegetation.
lake Study
The DNR has hired the University of Minnesota to collect data on the aquatic plant community in
Silver Lake following the 2008 herbicide treatments (Attachment 4). The draft study reflects a
decrease in curlyleaf pondweed and Eurasion watermilfoil, which is encouraging. It also reflects
a decrease in native aquatic plants such as coontail, Canada waterweed, and bushy pondweed
and a decrease in water clarity. The DNR was hoping to see the native plants increase as
nonnatives decrease, so they are concerned with this trend. They are however committed to
the long term benefits of the project and have agreed to continue with the Total Lake Treatment
Pilot Study this year. Brittany Hummel, Aquatic Plant Specialist with the DNR, will be present at
the Environmental and Natural Resource Commission meeting to discuss the study.
Stakeholder Meetings
Earlier this year the Minnesota Pollution Control Agency (MPCA) hosted a stakeholder meeting
to discuss issues associated with Silver Lake. Included in this discussion were representatives
from the DNR, MPCA, Board of Water and Soil Resources, Silver Lake Improvement
Association, Valley Branch Watershed, Maplewood, North Sl. Paul, Ramsey County, Senator
Chuck Wiger, and Representative Leon Lillie. The representative cities and the DNR indicated
that they do not have available funds to increase their share of the herbicide treatments at Silver
Lake this year. Based on these discussions it was understood that the City of Maplewood could
feasibly fund the same amount as last year, $8,250, as long as the conditions imposed by the
city council were met, which include additional lake studies and the implementation of
stormwater best management praGtices by the association.
Best Management Practices
Dr. Manthei submitted the following information on the association's attempts at implementing
stormwater best management practices along the Silver Lake shoreline:
. Several people have made improvements to their properties.
. Paul Anderson received a grant from the Valley Branch Watershed District to complete
native plantings along the shoreline of his property.
. Tom Germscheid worked all summer on his lake shore and drainage improvements from
his property
. Dave Liukonen put large rocks in front of his lake shore to stop the soil erosion and also
stop the geese from using his yard as a waste dump.
. Dr. Mike Manthei worked on an elevated rain garden to catch water coming off the roof
on the west side of his house and will be working on the east side of the house this year.
Dr. Manthei also hopes to apply for a grant from Valley Branch Watershed District to do
shoreline restoration this year.
. Dr. Manthei and his neighbors near him do not mow all the way to the shoreline, so this
helps to buffer what goes into the lake.
. Dr. Manthei and other neighbors who use the lake for irrigation do not fertilize so this
helps the lake shore and the plant communities in the lake.
2
. The association is working to educate more home owners on the importance of
stormwater best management practices.
. Several lake shore owners went to the lakeshore and rain garden seminars hosted by
the Ramsey-Washington Metro Watershed District and the City of Maplewood last year.
. The association will be holding their annual meeting on Thursday April 2. They have
invited Angie Hong to talk to the association about the Silver Lake shoreline and the
association asked her to start the process of education for lake shore owners on
becoming better stewards of the lake.
RECOMMENDATION
Fund Silver Lake Association's request for herbicide treatment of Silver Lake at the same rate
as last year, $8,250. Future funding should be conditioned on additional lake studies and
additional stormwater best management practices being implemented by the homeowners.

Year Three
Dear City Manager:
I am writing to you. on behalf of Silver Lake and Silver Lake Improvement Association, Inc. in Ramsey
County. I am the President of the Silver Lake Improvement Association, Inc. We created this
Association to help restore Silver Lake. Last year, we obtained permission from the MN DNR to treat
the whole lake, because of the non-native exotic invasive plants that are in this lake (Curly Leaf Pond
Weed and Eurasin Water Milfoil). We were awarded a Grant for $10,000 last year (2008). We have
been awarded again a Total Lake Treatment Pilot Study Grant for this year (2009).
We have the estimate now for total lake treatment based on the treatment from last year. The final
costs will be determined by the spring plant survey conducted by the MN DNR. The cost of this
treatment will need to be shared by the City of Maplewood (your park on the north end), the City of
No. St. Paul (their park on the south end), the City of Oakdale (their area of the lake adjacent to
Century Ave), and lakeshore owners surrounding the lake (they will be asked to contribute $384-
1000). Last year, Ramsey County and Valley Branch Watershed District contributed as did other No.
St. Paul neighbors and businesses. We will try to include other stakeholders as they are identified to
us.
We will be treatina onlv Curlv Leaf Pondweed this year based on the results of last year's
treatment.
In the year of 2005, two people from our lake board measured very carefully the lake shore perimeter.
We have divided the linear feet into a percentage. Please see the percentage listed below.. This
amount (in dollars related to the Cost of treatment) is the minimum participation requested. Please
note: the amount requested is for this year, year three (2009). We are committed to a 5 t010
year plan to restore this lake. Please use these percentages as everyone else has contributed
for two years using these numbers. We respectfully request your yearly participation.

We are hopeful that the costs for treatment will not exceed $36,332 this year. This amount
uses the same application rate of Aquathrol K (0.75ppm) as last year. If the MN DNR requires
us to change the application rate to 1.00 ppm then the bid amount would be $41,416. We are
going to estimate for the .75 ppm treatment rate, therefore Maplewood's fair share of the
$36,332 will be $11,990. The check can be made out to Silver Lake Improvement, Inc.
Last year, we requested your participation in this very important public project. You did not contribute
your fair share. Your park borders on this lake and as good citizens it is in your best interest to
participate this year to the 100% level requested. We need your full participation if we are going to
arrive at the necessary funding amount needed to complete this public project.
As for the other Cities, Ramsey County and Valley Branch Watershed District, I sent letters to the City
Managers of Oakdale and No. St. Paul. I did not attend any of their meetings. These two cities paid
their fair share. For Ramsey County, an employee Terry Noonan approved our request for funds via
the internet. The Valley Branch Managers voted on our request after I attended one of their
meetings. These requests were simple and required minimal energy. We request that Maplewood
follow the same pattern as the other two cities regarding the sending of their funds.
We have seen that Maplewood is beginning to improve their park on the North End of Silver Lake. It
does not make sense to improve a park on any lake without improving the lake. A very high
percentage of Maplewood residents use this lake. The boat ramp is within Joy Park which brings
people into Silver Lake. People fish from your lake shore surrounding the lake on the North Side.
We are hopeful that you will contribute to this project that is actually improving your park.
Enclosed is the result of the treatment of aquatic plants that was done for the MN DNR last year. As
you can clearly see, the treatment helped the lake by reducing the target non-native plants. Coontail
and Elodea were reduced more than expected last year either due to Renovate and/or because of the
delayed treatment application date. This is why the MN DNR wants to do only Curly Leaf Pond Weed
this year. The lake was also turbid las~ year probably due to low water level (low rain fall) and
increased boat traffic. We need to continue working several years longer to be able to control the
exotic species (especially Curly Leaf Pond Weed). Please join the other stakeholders and help our
efforts to restore Silver Lake.
If you have any questions, please feel free to contact me. Please make your check payable to:
SILVER LAKE IMPROVEMENT ASSOCIATION. INC. by April 15th,2009.
If you have any questions, direct them to me:

Councilmember Rossbach moved to approve the Silver Lake Herbicide Treatment Fundinq
Request. which represents the city's 27.5 percent share of the shoreline ($16.500 X .50= $8.250).
One half of those funds should come from the Environmental Utilitv Fund and the other one half
should come from Parks Maintenance or Recreational Funds. Further addinq that the fundin!! is
for one year onlv and that future funds will be conditioned and documented on additional
lake studies and stormwater best manaqement practices bein!! implemented bv the Silver
lake homeowners.
Councilmember Juenemann made a friendly amendment clarifing that the funding is for one year
only and that future funds will be conditioned and documented on additional lake studies and
storm water best management practices being Implemented by the Silver Lake homeowners.
Councilmember Rossbach accepted the friendly amendment.
Mayor Longrie stated for the record she would have preferred to see the studies and the
chemistry that have been discussed this evening. Mayor Longrie said she has a double major in
chemistry and biology. (Someone in the audience shouted that this information is available
online.) However, Mayor Longrie stated she wanted to see this information before voting so she
could better understand things. Mayor Longrie was concerned about where the financing would
come from. She thinks the idea of having different associations such as lake associations coming
to the City of Maplewood and applying for charitable gambling funds looking for money will be
common.

Mayor Longrie said this is the opening of the public policy. She would like to be a voting member
so the city can be partners. Without that the city is just a money bag. These are the types of
things that she weighs and balances when voting. She felt she didn't have the appropriate
information to make a good, balanced, and informed decision. She is concerned about the
chemicals that were put in the lake last year and the impact on the lake. Now those chemicals
aren't allowed. These are the questions she hasn't heard answers for.

Preliminary evaluation of lake-wide herbicide treatments for controlling
curlyleaf pondweed and Eurasian watermilfoil in Silver Lake (DOW# 62-0001)

[Draft received on 28 .January 2009]
Pl'oject Overview
The Minnesota Department of Natural Resources (MNDNR) and University of Minnesota (UMN) have been
collaborating since 2006 to evaluate the use of whole-take herbicide treatments for controlling nuisance growth of
curlyleafpondweed (potamogeton crispus) in Minnesota lakes. The specific objectives of the project are to:
I. Determine the effectiveness of treatments for reducing curlyleaf distribution and growth density
2. Determine the effects of treatments on native plant distribution, diversity and growth density
3. Determine if successive lake-wide treatments reduce the number of curlyleafturions (reproductive buds) in lake sediments
During each year of this project, We conducted point-intercept aquatic vegetation surveys, measured plant biomass
(estimate of growth density), collected water quality measurements, and sampled lake sediments for curlyleaf
turion in 13 study lakes, including Silver Lake (Table 1).
Table 1. Swumary of aquatic vegetation (A V), bi~mass (BM), and turion density surveys completed in 2005 (MNDNR), 2006, 2007, and

Summary of Results
Silver Lake (Ramsey County, MN, DOW 62-0001) is a moderately fertile (mesotrophic) lake with a history of
moderate water clarity (Table 2). The lake has a history of abundant plant growth, and contains established
infestations of two non-native invasive plants, Enrasian watermilfoil (M spicatum) and cnr1yleafpondweed (P.
crispus). In 2006 and 2007, aquatic vegetation was found at 90-100% of the sampled littoral sites during all
surveys, but in 2008 vegetation appeared to decline in abundance from t 00% vegetated in May to 30% in August
(Table 3). The dominant plant taxa generally declined in abundance in 2008. Water clarity also declined dnring
the monitored period, with average May-September Secchi transparency dropping from about 2.5m in 2005 and
2006, to about 1.6m in 2007 and 2008 (Table 2).

Native Aquatic Plants
Coontail (c. demersum) was consistently the most common plant during the monitored period, occurring at
80-100% of sampled littoral sites in 2006 and 2007; however, it declined in 2008 from 80% occurrence in May to
10% in August (fable 4). Elodea (E. canadensis), the next most abundant native ptant, showed a similar pattern,

occurring at 30-50% of the sampled littoral sites in 2006 and 2007, but declined in 2008 from 30% in May to 10%
in August. Two other common native ptants, bushy pondweed (N. flexilis) and large-leaved pondweed (P.
amplifolius), also showed notable declines in occurrence from 2006 to 2008 (fable 4).
Non-Native Invasive Plants: Eurasian Watermilfoil and Curlylea! Pondweed
Eurasian watermilfoil was found at 50-70% of the sampled littoral sites in 2006, but was not found during any of
the surveys in 2007, and ouly occurred in May of2008 at about 10% ofthe sampled sites. Curlyleafpondweed
was found at 60-70% ofsampted littoral sites in May of2007 and 2008, but occurred at less than 5% of sites in
June of both years (no May survey in 2006), likely due to treatment. Curlyleaf pondweed turion density dropped
considerably from 210 turionslm2 in 2007 to 10 turions/m2 in 2008 (fable 5), suggesting a decline in turion
production due to the control of curlyleat: These results suggest that the herbicide treatments are effectively
controlling both of the target non-natives. Although curlyleafpondweed abundance in May did not decline during
the monitored period, the absence of curlyleaf in June, normally the period of peak growth, and the large decline
in turion density suggest that the treatments are minimizing negative impacts to recreational use and are reducing
turion density to a level that should translate into reduced curlyleaf abundance in 2009.

University of Minnesota.
Summary:
. Eurasian watemrilfoil (M spicalurn) and curlyleafpondweed (P. crispus) appear to have been effectively
controlled by herbicide treatments in 2007 and 2008.
. Although May curlyleaf abundance did not decline over the three-year monitoring period, little curlyleaf was
found in June of 2007 and 2008, and curlyleaf lurion density declined substantially.
. Although Silver Lake supported abundant plant growth in 2006 and 2007, plant abundance declined
substantially during the summer of2008. Most notably, coontail (c. dernersurn) declined from 80-100%
occurrence in 2006 and 2007 to 10% in August of2008. The decline in native plant occurrence may be
associated with the decline in water clarity.
. Water clarity declined from 25m in 2006 to I.6m in 2007 and 2008 and chlorophyll levels in 2007-2008 were
higher than most previous years.
. The University of Minnesota plans to continue monitoring Silver Lake in 2009 (Ajay Jones).
