Director of Public Works FROM: Shane Missaghi, Water Resources Engineer SUBJECT: MEDICINE LAKE WATERSHED SUB -COMMITTEE RECOMMENDATIONS FOR: MEDICINE LAKE WATERSHED IMPLEMENTATION AND MANAGEMENT PLAN As instructed by the Council in their June 6, 2000 meeting, the Plymouth Environmental Quality Committee (EQC) formed a citizen advisory subcommittee to develop an implementation plan for Medicine Lake watershed. Subsequently, the EQC appointed the nine member Medicine Lake Watershed subcommittee on October 4, 2000. The sub -committee held ten meetings to review a variety of information on watershed and lake management as well as study a number of case histories and work plans previously developed for Medicine Lake. Background information and support materials were provided by Department of Natural Resources, Hennepin Parks, a professional ecologist (Mr. Steven McComas), and City staff. Early on, the subcommittee established a vision statement "To establish strategies, Best Management Practices (BMP), actions and solutions to ensure/improve the health of Medicine Lake and the watershed for generations." This vision statement then became the guideline for developing the following three primary goals: 1. Improve water quality to support full-body contact recreation; 2. Manage the lake in a manner that supports a healthy and diverse fish and plant population; and 3. Increase citizen awareness of their impact on the lake and increase their participation in achieving goals. No council action or motions are requested at this study session meeting. If the Council ultimately approves the plan, the subcommittee recommends that the City Council begin the program by mailing a newsletter to residents and businesses of the Medicine Lake Watershed, explaining the implementation plan and their role in improving the water quality of Medicine Lake. Next, the subcommittee is recommendiag formation of an Aquatic Vegetation Management Group (AVMG) to evaluate and implement specific strategies to control exotic and invasive aquatic plant species and promote the groxvili of native species- The subcommittee has N1pw\Engineaing\WTRQLTriULW SubcomWOUNCIL MEMO.doc elected to concentrate on long term and sustainable management techniques rather than the quick fix" approach. It was concluded that chemical treatments such as herbicide or alum treatment (both the in -lake and the in -stream treatments), are effective tools that provide quick, but not necessarily long term solutions. The subcommittee considered these chemical treatments as a last resort. The subcommittee is rather taking a sustainable approach in managing Medicine Lake, relying on proven and tested watershed wide implementation activities. A total budget of about $ 2.3 million dollars is recommended to complete the plan and achieve the goals. This budget could be funded by a combination of the City's Surface Water Utility Fee, the Bassett Creek Watershed Management Commission and grants.

Introduction: History: On February 15, 2000, the Plymouth City Council (City Council) adopted the Water Resources Management Plan (Plan). That Plan contained ten policies related to water quantity and quality: erosion control; wetlands; public participation, information and education; monitoring, maintenance and inspection; recreation; fish and wildlife; groundwater; and finance of the Plan. Policy 5 of the Plan stated that the City would "Increase public participation and knowledge in the management of water resources". In an effort to accomplish that goal the City Council, at their June 6, 2000 meeting, directed the Environmental Quality Committee (EQC) to establish a Subcommittee to work on water quality issues concerning the Medicine Lake Watershed. At their August 2, 2000 meeting the EQC approved a recommendation to form a nine (9) member Subcommittee composed of: two EQC members, two residential lake shore property owners, two business owners within the watershed, two Medicine Lake Watershed residents, and one education representative. A notice was placed in the Sun -Sailor newspaper and the City's website to receive applications. The EQC interviewed the applicants on October 4, 2000. In addition, the following agencies acted as liaison and sources of information for the committee: Minnesota Pollution Control Agency, Bassett Creek Watershed Commission, Hennepin Parks, Plymouth Park and Recreation Dept., and MN Department of Natural Resources. Purpose: The purpose of the Subcommittee was to review and prioritize an implementation plan for Medicine Lake Watershed in accordance with the City's Comprehensive Plan and Surface Water Resources Management Plan. B. Background On October 4, 2000, the Subcommittee was appointed by the EQC to study the options and make recommendations to improve the water quality of Medicine Lake. Nine people were appointed from five different areas and backgrounds (see Acknowledgment Page 2). The Subcommittee held ten meetings. 1--ach meeting followed a particular theme or locus: Page 2 ML Recommendations Oct. 19, 2000 Nov. 30, 2000 December 14, 2000 Feb. 1, 2001 Feb. 22, 2001 March 29, 2001 April 26, 2001 May 24, 2001 June 5, 2001 June 13, 2001 (proposed) July 17, 2001 (proposed) The Big Picture Getting on the Same Page How Does it All Work?

Background information and support materials were provided by a professional ecologist and staff from the DNR and Hennepin Parks. See Appendix C for minutes and agendas of meetings. C. Goals The goals established by the Medicine Lake Watershed Subcommittee reflect those set forth in the City of Plymouth Comprehensive Plan and the City's Surface Water Resources Management Plan, as follows: Deliver good quality storm water run-off to lakes and wetlands at acceptable rates and volumes, while reducing pollutant and sediment loading and stream bed/stream bank erosion and Nvater quality degradation." (Policy 3.3.3 of the City of Plymouth Comprehensive Plan.) Increase clarity and reduce total ,phosphorus and chlorophyll a concentrations, working toward the goal for total phosphorus established by the Bassett Creek Watershed Management Commission." (Plymouth Surface Water Management Plan) The Medicine Lake Watershed Subcommittee's goals reflected the above policies in stating that its vision is: To establish strategies. Best Management Practices (BMP), actions and solutions to ensure/improve the health of Medicine Lake and the watershed for generations." This vision was the guideline for developing three primary goals: 1. Improve water quality to support full-body contact recreation; 2. Manage the lake in a manner that supports a healthy and diverse fish and plant population; and 3. Increase citizen awareness of their impact on the lake and increase their participation in achieving goals. These goals help ensure that the recommendations of the Medicine Lake Watershed Subcommittee are in accord with Plymouth's Comprehensive Plan and Surface Water Management Plan. The following is a list of these objectives and benefits: [Number in ( ) refer to goals] 1. Establish a summer average concentration of 38 ug/L for in -lake phosphoroub. (1) 2. Work toward a minimum water clarity of 1.5 to 1.75 M (5-71. (1) Page 3 ML Recommendations 3. Control and reduce sedimentation at critical points in the lake. (1 & 2) 4. Re-establish native plant population to reduce exotic species and increase the opportunity for native and desirable plant species. As lake water clarity increases, aquatic plants growth will increase. The lake plan for aquatic plant species should provide the opportunity for native and desirable plant species to out -compete the nuisance or the invasive species. (2) 5. Improve and enhance blue gill/bass populations to enhance the habitat for desirable species and neral water quality. (2) 6. Control nuisance population of plants and establish native vegetation that supports local wildlife, reduces and prevents erosion and replaces mon6-typical areas (i.e. reed canary grass) with more diverse species. (2) 7. Work with the Bassett Creek Watershed Management Organization, AMLAC, Hennepin Parks, the DNR, residents, and businesses as a part of an overall water quality improvement strategy for the lake. 3) 8. Reconcile lake surface use conflicts to maximize recreational experiences for maximum number of users, taking into consideration rights of abutting property owners and stated water quality goals. 9. Create an education plan (Appendix B) for residents, businesses and users of the lake to achieve water quality goals.(3) 10. Create an awareness of good management practices through an educational program using action - based case studies and examples to show how citizens and businesses can practice good management to make a difference in the quality of water of the lake. (3) 11. Control aquatic and nuisance plants through a nutrient management program. Case studies demonstrate that aquatic plants, both desirable and undesirable, can be effectively managed by controlling the concentration of nutrients such as Nitrogen or Iron. (2) 12. Improve swimming. (1) 13. Eliminate bad odors through control and management of algae and other undesirable plants. (1) 14. Promote citizen stewardship by creating opportunities for area volunteers to get involved in lake improvement efforts and monitoring. (3) All of the above the recommended implementation items were evaluated based on how they met the Subcommittee's goals, objectives and benefits. Page 4 ML Recommendations D. Recommendations: The Subcommittee's Implementation Plan Recommendations (Appendix A.) summarizes the Subcommittee's recommendations for Medicine Lake. As previously noted, these recommendations are based on the vision, goals, objectives and benefits established by the Subcommittee. The Subcommittee has elected to concentrate on long term and sustainable management techniques rather than the "quick fix" approach. An annual budget of about $500,000 per year is recommended to complete the plan and achieve the goals. The Subcommittee's Implementation Plan will begin immediately by disseminating the Subcommittee's recommendations to businesses and residents and by forming an Aquatic Vegetation Management Group AVMG). Education is a vital component of the Implementation Plan and the Subcommittee recommends that the City Council begin the program by mailing a newsletter to residents and businesses of the Medicine Lake Watershed explaining the Implementation Plan and their role in improving the water quality of Medicine Lake. In addition, the AVMG should be formed to evaluate and implement specific strategies to control exotic/invasive aquatic plant species and promote the growth of native species. The recommendations of the proposed Implementation Plan are divided into three areas: I. The External Factors: These recommendations address nutrient and pollutant loading in the lake. Activities include increased street sweeping; constructing wetland or wet detention ponds to treat in- coming surface water; source reduction by promoting alternative landscaping; proper lawn care; reducing the use fertilizer, especially those with phosphorous; and storm drain stenciling. II. The Internal Factors: These recommendations address factors that contribute to the lakes internal loading. Activities include aquatic plant management and harvesting, roughfish removal, select dredging, and alum treatment. III. The Watershed Management Activities: These recommendations address factors throughout the watershed as they impact lake water quality. Activities include up -land and in -lake best management practices, education, forming the AVMG, and management strategies to deal with shoreline erosion, nuisance aquatics, swimmers itch, geese, and lake crowding. The proposed plan spans five years, through the year 2006, and includes an evaluation component in the fourth year.

Structural BMPs Options, such as: Wet or Dry Background. The Bassett Creek Watershed Management Commission developed a watershed management play: Detentions & Constructed Wetlands, options 6,8,9a, I Oa,& for Medicine Lake (BARR Eng. March 2004), to establish and provide guidelines to meet the water quality goals I I . set for Medicine Lake, The plan lists eleven site specific structural BMPs, as well as a number of options with combinations of the eleven sites plus other BMPs. The Subcommittee adopted Option 24 of the report which is the combination of these structural BMPs, excluding the chemical treatment of the storm water. Structural BMPs remove a significant amount of the surface runoff water pollutants, nutrients (phosphorus), and sediments. Detaining the surface runoff water allows for the both the solids (dirt & sand) and suspended sediments articles to settle as well as rovide an opportunity for biological treatment. 2. Source Reduction, Lakescaping Source Reduction or Nonstructural BMPs rely on prevention, by eliminating and controlling the pollutant, nutrktrnts. and sediments right at the source. These techniques or BMPs are employed generally to control both the quantity and the quality of the runoff, 73. Reduce Nutrient, fertilizer, leaves, stenciling These activities focus specifically on practices that can reduce the nutrient loading into the lake, such as removing leaves from the streets before they get into the storm sewer system, stenciling catch basins to help keep . the system clean from trash and pollutants. and education on Enj! and proper use of fertilizer. 4. Alum dosing stations (in stream injection) Alum treatment plants are used in combination with wet detention ponds to more effectively remove phosphorus from storm runoff. Aluminum sulfate is added into the stream, where alum binds with phosphorus and forms a floc. The runoff is then detained in a wet pond where the floc is settled and collected before the water is discharged into the lake. The Subcommittee concluded that alum treatment is an effective tool that provides a short term (up to 7-10 years) solution. The subcommittee considered it a last resort option for year 4 of this pjaFri. Internal Factors: 1. Aquatic plant harvesting, mechanical 1 physical Mechanical Control of aquatic plants provide immediate relief in many cases. It is well suited for larger lakes control such as Medicine Lake. Mechanical control would: ] )remove in -lake plant biomass, a source of nutrients often released by fall die -back and decay; 2) reduce sediment accumulation by removing organic matter that normally decays and adds to the bottom sediments; 3)produce harvested vegetation that can be easily composted and used as a soil enhancement. The Balance of desirable plants versus the non -desirable plants is an essential part of aquatic ananagement. As22. Aquatic Plant Management, re -introduction the water quality of the lake improves so will the growth of aquatic plants. Establishing the desirable plants, prevents the excessive growth of invasive or nuisance lants. 2b. Rough fish removal. Rough fish or boltcam feeders are of particular problem because of their feeding action which constantly disturbs and re -suspends [lie lake sediment. Sediment re -suspension introduces a significant amount of nutrients back into the system+lake. In some cases, rough fish also up -root many desirable plants which further degrades water quality 3. Select Dredging. Dredging or removing the layer of the most highly enriched matcrialsilake sediment is a effective way of removing accumulated sediments to restore fish habitat. However, dredging large areas also has high potential to create severe and serious impacts. Select dredging will be used on site specific areas to remove accumulated sediment and road sand. 4. Alum Treatment (In -Lake Treatment) In -Lake Alum treatment is similar to in -stream alum dosing, stations. In an in -lake alum treatment, the alum is injected into the water at a calculated depth and the generated floc is settled to the bottom of the lake binds the phosphorous and reduces internal loading.

It also assures that aquatic plant management is consistent with other management plans." Furthermore, this group will evaluate and implement various methods and technique in aquatic plant management through collaboration with area agencies and interested parties. The Department of Natural Resources and Hennepin Parks are both veri 'Atpportive o1 working with such a group. The sub -committee is proposing to minimize shoreline degradation and shoreline erosion through aggressive lakescaping and shoreline mitigation efforts. The lakescaping techniques utilize sustainable bioengineering methods (using plants to stabilize the ground on up -land and along the shoreline) to minimize erosion. A well vegetated and established shoreline is an essential part of take management ;end requires a long-term approach. Lakcscaping altit IzG'i3nic res taw rise of I}w:al native plants, providing a natural habitat. This item will be part of the Aquatic Vegetation Management Group. The Aquatic Vegetation Management Group is expected to identify problem species and recommend necessary corrective measures to mitigate the problem. No single one method may address all the issues or successfully eliminate any one invasive specie. The Medicine Lake Watershed Sub -committee recognized that issue and they have prioritized the available aquatic - plant control methods as follows. nleclt:tntcal, physical, biological, and chemical methods. Some of these items will be implemented through volunteer programs or in collaboration with other agencies. Some items may also be addressed through other activities such as roughFish removal which is also addressed under Internal Factors 2b. However, majority of these items will be addressed as funds are available. Appendix A5 ML Recommendations APPENDIX B MEDICINE LAKE WATERSHED SUB -COMMITTEE EDUCATIONAL PLAN Appendix B1 ML Recommendations The over -arching purpose of the Medicine Lake watershed education plan is to increase citizen awareness of their impact on the lake, and increase their participation in achieving goals established to address water quality. Goal Medicine Lake education will incorporate community -building measures to incr^as^ awarenes z and sens^ of ownership in the health of Medicine Lake. Objectives Public education for the Medicine Lake Watershed will address the overall goals of the subcommittee with four educational objectives: 1. Help property owners understand the goals and benefits of improving the water quality of Medicine Lake and its watershed. 2. Help property owners understand their role in improving and maintaining water quality of the Medicine Lake watershed. 3. Help property owners develop a sense of stewardship of Medicine Lake watershed. 4. Enlist the efforts of property owners in improving the water quality of the Medicine Lake watershed. Action items for citizen awareness: 1. Establish a logo depicting the Medicine Lake watershed. Distribute magnets with the logo imprint. 2. Direct mail Publish a newsletter to be distributed periodically to all for property owners of the Medicine Lake watershed. 3. Signs Post lake -side signs on public property delivering water quality information. Post signs along City walking trails that carry a specific water quality message. Establish neighborhood volunteers who would post signs with educational messages. Post trail signs about picking up pet waste. 4. Media Produce and/or disseminate videos for Public Channels. Establish a schedule of video presentations on Public Channels (e.g. 3 P.M. Sunday airing of videos on healthy lawns, etc.) Post materials on the City's web site.

Meeting Minutes The minutes of October 19, 2000 meeting were approved with the correction of adding Ms. Terri Goodfellow -Heyer and Ms. Karen Haht's name to the Members Present. The Committee decided to assign Shane Missaghi as the Facilitator of the Committee and not have a chairperson. Presentations Shane Missaghi provided a brief presentation and explanation on Best Management and Reports Practices and shared with the committee the latest Minnesota Pollution Control Agency's publication on Best Management Practices. Mr. Barten gave a presentation on various lake classification methods used by state agencies, local government and other entities. Mr. Barten explained how some water bodies are classified into different categories depending on the size, water quality, depth and other physical and chemical. variables. Mr. Barten also announced that Hennepin Parks, in partnership with other agencies, have been awarded a National Impact Grant which will allow them to study in detail the water quality of Medicine Lake and provide live information on the Internet (lakeaccess.org). Plan The focus of the group for this meeting was to form a consensus on various problems Development associated with Medicine Lake. The group worked in three small groups where each oup sw4ied the Plymouth Water Resources Management Plan, Medicine Lake study or a case study to better understand the objectives of these plans. Later, the committee worked in another set of groups (composed of at least one member from each of the previous groups) and worked on establishing the main issues or the problems associated with Medicine Lake. The following are the general consensus of the group on these issues: Page 1 of 3 N.9pwlEngineeringiwmQLrAuLwsubcomwinutes_!! 113000approved.doc Approved The group's general assessment of the major problems facing Medicine Lake are as follows: excess weeds, excr. i phosphorus levels in the lake, sedimentation from Highway # 169, bacteria contamination at the beach area, erosion, lack of ecological restoration (wetland restoration), swimmers itch, surface use conflicts/issues, shoreline degradation/erosion, apathy, exotic species, invasive species. The Committee agreed that our expectations and goals set for the lake by various management plans are realistic. We may not be able to absolutely reach all the numerical water quality goals. However, in general, most of these goals seemed to be attainable, as long as we have a balance where obtaining one goal does not sacrifice other uses of the lake. Not all of the people will be happy, for instance, we need to recognize that perhaps by increasing water clarity, we may encourage plant population, which may inhibit boating or v.s. the increase use of boating may cause the re -suspension of the lake sentiment and decreasing water clarity. Again, we need to establish a well balanced management plan. It is important to realize that we may not necessarily achieve all goals, but in general, improve the lake's water quality and its use. Generally, we want the lake available for swimmers and fishing with: elimination of noxious weeds, control the geese problem, minimizing sedimentation, and of course, we want a healthy biological water cycle in the lake. Last, the Committee agreed that there are definitely solutions that can help us obtain our goals. Some of these solutions include: mechanical weed harvest, use of herbicides, dredging portions of the lake, increasing educational programs for all ages, goose management, use of retention ponds and controlling bottom sediment, manage boating through education, naturalize shoreline area to prevent shoreline degradation, eliminate rough fish, and educate and involve communities so they better understand their impact on the lake.

To remove Greg Schlink from member's absent. The minutes were approved. Update Ms. Haht gave a brief report on the December 14, 2000 meeting where Steve McComas had provided a presentation to the committee under the title "How Does It All Work". Ms. Haht also mentioned the concern of the Environmental Quality Committee (EQC) on developing the educational plan and raised the question of the need to establish an educational plan. Ms. Christian asked perhaps we can have the watershed take over our educational effort for the Medicine Lake area. Councilmember Black indicated that we need to come up with at least some minimum educational activities for this area and although we can go ahead and collaborate with other agencies and departments as well. Mr. Barten informed the committee that he has been appointed to be on the Technical Committee of the Bassett Crcek Watershed Second Generation Water Plan. Ms. Christian handed out articles on herbicides, macrophytes survey of Medicine Lake and a phosphorous bill that is likely to go through legislation. Page 1 of 3 N. IpwlEngineeringlWTRQLTYWLWSubcomllNLWS 010101.doc Review and As discussed previously, the group felt they need more detailed Discussion on Right discussion on various solutions and possible problems of Medicine Lake Solutions for the before they can prioritize any specific implementation plans. Right Problems The first item of discussion was the general goal for Medicine Lake as well as for the committee. Ms. Christian shared with the group on the differences of the first and the second generation plans objectives. Mr. Hedberg talked on the balancing of goals and objectives as well as what is practical and what is achievable and that we as a group might have to select certain goals and sacrifice some other goals. Ms. Goodfellow -Heyer explained that perhaps goals need to be specific on what we need to achieve and she provided the following framework of a goal for the group: To establish strategies, best management practices, actions and solutions to insure/improve the health of Medicine Lake and the watershedfor generations. After some discussion, the group decided to accept that statement as a vision for Medicine Lake and established. the following corresponding three goals: 1. Improve water quality to support full body contact recreation. 2. Manage lake to support healthy diverse fish and plant population. 3. Increase awareness and participation of citizen's impact on the lakes and to obtain goals. Mr. Barten shared with the group on the idea of setting goals and objectives. He mentioned that setting goals for the lake management is to manage for uses and that these lakes are in some sort like recreation parks. We need to know what people want to use from these lakes in or&r to manage them properly. We nt;J to also define -%` ho the us :rs are. For instance, from Hennepin Parks point of view, the lake needs to be swimable, provide adequate fishing and provide for boating. Mr. Barten also explained that whatever the goals, some uses will be limited. It is not practical to picture a whole lake to provide opportunity for various uses throughout the lake. It is possible to manage different areas of the lake for different uses and goals need to be set with that in mind. For instance, once water clarity increases in a lake, macrophyte population will increase as well. The group needs to discuss if that is acceptable unless we design or plan for accordingly we will have conflicts in the future. One idea would be to map the lake for different appropriate uses. Based on these discussions the follow objectives were developed to support the groups goals and vision: 1. To establish an average of 38 parts per million of phosphorous Page 2 of 3 N. owlEngineeringlWTRQLTNMLWSubeomWLWS 010/0/.doc concentration for summertime and not to increase over 42 parts per million (Goal No. 1). 2. To have water clarity at 1.5 to 1.7 meters (5-7 feet) (Goal No. 1). 3. Stop sedimentation (Goal No. 1 and 2). 4. Reestablish native plant population to reduce exotic species (Goal No. 2). 5. Improve and enhance bluegill, sunfish and bass fish population Goal No. 2). 6. Control nuisance population of plant and wildlife (Goal No. 1 and 2). 7. Work with Bassett Creek Watershed Management organization, lake association, Hennepin Parks, DNR and businesses as part of an overall lake improvement strategy (Goal No. 3). 8. Create an educational plan for uses and watershed to achieve goals Goal No. 3). - 9. Reconcile surface use conflicts to maximize recreation and experiences for maximum number of uses (Goal No. 1). Next as an exercise, the group decided to review the problems and solutions that were provided by Mr. McComas' presentation and individually evaluate each solution to see how it satisfies the objectives that were developed by the group. The committee also decided that each member should be mailed a copy of the problems and solutions list plus a list of our objectives and each member is to individually evaluate the solutions and send their comments back to the City's office by February 16, 2001 so the material can be compiled and provided to the members before the committee's next meeting on February 22, 2001. Ms. Haht will contact Ms. Wilcox to see if she is intending to attend future meetings and members attendance will also be discussed at the next Environmental Quality Committee meeting.

Page 1 of 3 N.Ip-1Engi—ri-g1WTRQLMULW SubcomWLWS 02210/.doc Various Sources of Mr. :Moore handed out the table which summarized the cash flow and Funding for the Plan funding requirements for the Surface Water Improvement Program Implementation (SWIM). The table included the current operating, other unfunded operating costs, capital expenditures, fee reduction, incentive programs and school revenue deferral for the year 2001 up to 2010. Mr. Moore mentioned that funds have been generated so far through taxes, but in the future most funding will be coming from the SWIM fees. Mr. Moore also explained there is funds in the various categories and their income and expenditures.' He mentioned that the three watershed membership dues, Bassett, Elm and Shingle, do not include capital improvement. All capital projects require input from the cities and all improvements are shared by city's based on a formula. Currently, Plymouth's share of the Bassett Creek projects are about 40%. Typical Bassett Creek Watershed projects include flood control and dam projects. There are some funds available from previous projects which could be used for the development of the Second Generation implementation plans. Mr. Moore mentioned that our first revenue collection from SWIM will be in July of 2001 and this will be our major funding and it is important to note that the Council has directed fees be used for existing programs funded by taxes for the Surface Water Management Fund, new activities and programs. We also have City capital improvements of about $850,000 for Parkers Lake and $750,000 for Medicine Lake, of which $400,000 is from capital improvement and 350,000 is proposed to come from Bassett Creek Watershed. After the overview of the cash flow and funding requirements for the SWIM program, there were a good number of questions. Mr. Moore also explained the tier system of drinking water fees and said it is a way to promote water conservation throughout the City. There were some additional questions on the availability of the $350,000 which is proposed to be funded by Bassett Creek Watershed. Mr. Moore mentioned that it is really a watershed concern and based on the philosophy that all the costs need to be shared by various cities. It is anticipated that the watershed would also support the activities on Medicine Lake, especially since it has been rated as a high priority by the Bassett Creek Watershed. Goals The table which included comments from many of the members on problems, solutions and objectives for Medicine Lake and its watershed was reviewed by all members and prioritized. Each major problem and its possible solutions were individually reviewed and then prioritized by the committee members (see attached table). Education All committee members were asked to send in their comments on the following three Mems which can be Compiled and reviewed at our next meeting. The three topics were: Page 2 of 3 N.•IpwlEnglnrrringlWTRQLTYWLWSubcomWLWS 022201.doc 1. List the top targeted issues in education. 2. Who is our audience and how can we monitor? 3.

The EQC members attended the workshops sponsored by the PBEP. Native and Aquatic Landscape Projects. (Continued Froin 1998). EQC continued to promote the use of native and aquatic plant species for our local ecological region. In 2000, we continued the development of the City Center Water Quality Demonstration site, by additional planting and in working with volunteer boy scouts. EQC developed and administrated a small grant program (S 3,500.00 total) to promote alternative landscaping practices using native and aquatic plant species which also promote water quality. Six home owners and one business took advantage of the program. EQC is recommending to direct all remaining (unused portion) funds toward the City's native plant model site at Hwy 55 & Plymouth Blvd. Felucation & Pro2rarn Promotion A. Education. Various articles were published in the City's newsletter as well as the local newspaper on our local environmental management. Four separate pamphlets on City Buffer and Wetland Ordinance, native planting, Erosion, and phosphate free fertilizers were published. David Shea, a long time EQC member until 1998 and Lee Keeley, a Gleason Lake resident were both named the Environmental Champions for the year 2000. EQC will purchase a Millennium Garden Brick for each individual as a token of appreciation. B. The Fifth Annual Pltiamouth Environmental Fair. (Continued From 1996) The 5ch Plymouth Environmental Fair was held at Kimberly Lane Elementary School. The event was a success with near 1000 participants. The project was a cooperative effort between the EQC, Wayzata School District, businesses, and the City's Parks, Engineering, Public Works, and Administration Departments. The event was promoted through the City's newsletter, local newspapers, cable T.V. and through posters. C. Phosphorus Free Fertilizer. (New Item) EQC worked to develop and implement the phosphorous fertilizer ban as outlined in the Plymouth Water Resources Management Plan. Members distributed signs to local retail stores to aid residents in their fertilizer purchase. D. Storm Drain Makers f roleet. (Continued From 1995) Permanent Storm Drain Markers were ordered for Medicine Lake area and will be installed in spring of 2001. E. Partnership With Area Schools. (Continued From 1995) During 2000, the EQC consulted with representatives from both the Armstrong and Wayzata High Schools. Both schools have developed programs to work on various environmental projects. Surface Water Management Plan.

The report references ten city-wide water quality policy goals as listed in the report. They encompass a wide spectrum which includes recreational uses and plant, fish, and wildlife management. Swimmable andfull use. These are reoccuring terms in a specific context. In the Surface Water plan there is a specific section with goals set for Medicine Lake. A major objective is to increase water clarity for the purpose of making the lake swimmable", i.e. suitable for full body contact, including «later skiing. Further, the lake is categorized as intended for "full use." The definition given for full use is broad as it implies. It includes "swimming, boating, fishing, aesthetics and runoff management." The Barr Report At a study session in the spring of 2000, Barr Engineering presented an extract of a report they had prepared for the Bassett Creek Watershed Management Organization. A major topic was the improvement of water clarity by reducing phosphorous. Recommendations to accomplish this suggested structural or engineering changes through the construction of wet detention ponds and alum treatments. Subsequently, the City Council asked the EQC to establish the Medicine Lake subcommittee to evaluate the complete range of issues affecting Medicine Lake water quality. Cornerstones ofthe Subcommilte's work The types of information we reviewed are listed in the report. Following up on our previous study sessions we reviewed the Barr report. We also studied a case history of a Wisconsin lake where alum was used as an in -lake treatment method. The many questions that were raised in last spring's study sessions were addressed in the course of our meetings. 6/13/01 Page 1 Medicine Lake Subcommittee Report MEDICINE LAKE SUBCOMMITTEE REPORT Presentation To The EQC On 6/13/01 Introduction of sub -committee members Preface This presentation is structured to aid the EQC in its review of the Subcommittee recommendations. It will need to be refined for presentation by the EQC to the City Council. There is a lot of material in the report. To avoid information overload this will be an overview of how the report is structured, and the thought process behind our recommendations. It seems simplest to open up the discussion of specific topics afterward. Please make notes of your questions and comments and hold them until the end of the overview. Our Process The subcommittee's review of history, work plans and case studies was comprehensive. We were assisted with capable technical experts. We have confidence in our recommendations. A long term Vision for the Lake. To establish strategies, best management practices, actions and solutions to insure/improve the health of Med Lake and the watershed for generations. What Needs To Be Achieved We developed these goals for improving water quality. Our method was to structure goals around the management of the lake for its intended uses. The goals are: 1. Improve w -iter quality to support full body contact recreation. 2. Manage the lake to support healthy, diverse fish and plant population. 3. Increase awareness and participation of citizen's impact on the lake and to increase their participation in obtaining the goals -set for the lake. To meet the goals, we developed a list of 14 objectives. These are shown starting on the bottom of page 3 and continuing on page 4 of the Subcommittee report. To help us formulate solutions for the objectives, we asked for continued input from our resource people. We evaluated the pros and cons of each type of solution in terms of efficacy and cost. Those that we determined to be viable are listed in our implementation plan. 6/13/01 Page. 2 Medicine Lake Subcommittee Report The Implementation Plan The following comments reflect the consensus of our group. Key elements It is a long term plan. It uses sustainable management techniques. The first phase of the plan spans 5 years and includes an evaluation component in the fourth year. We believe the techniques we've set forth to be practical, achievable, effective and affordable. The estimated cost averages out at about $500,000 each year. Throughout our process we stressed a sharing of resources and collaborative efforts to promote citizen education and stewardship. How the plan is structured Restoring the quality of a lake is complex. A combination of factors have created the problems in Medicine Lake. A combination of steps must be taken to remedy those problems. They are caused by run-off entering the lake and by an accumulation of nutrients and pollutants that have built up in the lake over the years. The resulting problems are largely man-made. For purposes of organization we categorized our recommendations in these 3 areas. They are designated with roman numerals. (section D I, II and III). I. The External Factors II. The Internal Factors III. The I4'atershed Manaavment Activities It is important to note that their order in the list does not imply that one is more important than the other. Remedial action needs to be taken in all three segments. The final results will be compromised if any of these three areas is left out of the final solution. They are interconnected. 6/13/01 There is no one magic buiiet or quick tier. Page 3 Medicine Lake Subcommittee Report The rationale underlyingthehe implementation items I. The Externa! Factors: (To reduce nutrients and pollutants from entering the lake) We ranked wet detention ponds as the best technical deterrent. They stop or reduce a variety of pollutants from entering the lake. A large amount of run-off entering the East side of Medicine Lake is virtually untreated. We asked City Staff to use their technical expertise to suggest the wet detention pond options from the Barr report which are most appropriate. We consider the changing of citizen practices such as lakescaping, type and amount of fertilizer applications, leaf management, etc. to be very important. When used as an in -stream or wet detention pond application, we view alum as a means of last resort. It is the most costly, addresses phosphorus removal only, and lasts for a limited time. II. Interna! Factors: (To overcome the pollutants and internal problems that are in the lake) Here, the sequence of treatments is important. 6/13/01 Plant and rough fish management may be sufficient and offers these advantages. Relief from this treatment method may begin immediately. It's cost- effective and if alum is needed later, prior treatment of plant life will add to the time window of the alum's effectiveness. When used appropriately, selective dredging removes accumulated sediment to restore fish habitat. We felt that in -lake alum treatment could be a viable method. It's possible that there is so much phosphorus in the lake that it can't be reduced sufficiently ithout using alum. However, again, it's expensive and its' length of effectiveness is limited. Therefore, we felt it should be deferred. For these reasons, to deal with internal loading we chose to begin with plant and fish management as the method to improve water quality. Hennepin Parks, in partnership with other agencies, has been awarded a grant which will allow them to study in detail the water quality of Medicine Lake. Live data will soon be transmitted from the lake to the internet, (lakeaccess.org). Data from this study and also from the Aquatic Management Vegetation Team can help determine the appropriate sequence of treatments. Page 4 Medicine Lake Subcommittee Report III. Watershed management: (Addresses an array of factors and practices throughout the Medicine Lake watershed which impact water quality. They include upland and in - lake activities such as: citizen education, shoreline erosion and lakescaping, nuisance plant and aquatic management, swimmers itch, geese management, and lake crowding and competing lake uses. ) Here, we consider Education and Evaluation to be the highest priority initiatives. As we all know, prevention is vastly less expensive than treatment. We need to begin a campaign of prevention through citizen education. We believe it should start immediately with the dissemination of the implementation recommendations to businesses and residents. A preliminary education plan is attached as appendix B. The Subcommittee recommends collaborating with the Bassett Creek Watershed Management Organization and sharing resources with other groups as well to promote citizen stewardship within the Medicine Lake watershed. Ongoing evaluation is necessary to make wise decisions. We strongly endorse the formation of the Aquatic Vegetation Management Group. Plant and aquatic management are complicated. To be effective they require extensive technical know-how and a pooling of efforts to obtain regulatory permits. This group would initiate informed activities to improve plant and aquatic conditions within the lake, and also help improve upland situations involving shoreline degradation, erosion, and control of invasive species. Funding is needed for data collection and analysis. This concludes the overview. Speaking on behalf of the Subcommittee we hope that the EQC will endorse the implementation plan we have proposed. 6/13/01 Page 5 Medicine Lake Subcommittee Report Excerpt from the March 2000 Barr Engineering Report Executive Summary The purpose of this Management Plan (Plan) is to establish priorities and provide guidelines for the cities of Plymouth, Golden Valley, Medicine Lake, New Hope, Minnetonka and Medina; the Bassett Creek Water Management Commission (Commission); and citizens for meeting water quality goals set for Medicine Lake. These goals were recommended for water bodies within the Bassett Creek Watershed in the Draft Water Quality Management Plan (Barr Engineering Company, 1993a). Medicine Lake, the second largest lake in Hennepin County, is considered the most important recreational water body in the City of Plymouth. The lake has multiple public accesses, and is intensively used during both summer and winter months. Fishing, boating, swimming, water-skiing and aesthetic viewing are some of the major recreational uses made of the lake. In addition, Hennepin Parks' French Regional Park and the City of Plymouth's East and West Medicine Lake Parks, and East Medicine Lake Regional Trail are all located along the lakeshore. The Metropolitan Council considers Medicine Lake a "Top Priority Lake" because of its multiple recreational uses and public access. The Association of Medicine Lake Area Citizens (AMLAC) also values lake water quality and has been involved in monitoring the health of Medicine Lake. Medicine Lake has typically fallen below the Commission's water quality goals. Trend analyses of historical water quality data for Medicine Lake indicate that while brief periods of poor water quality occur annually during late -summer, its overall condition has remained steady. This steady level of lake water quality, despite ongoing watershed development, is most likely due to the implementation of watershed BMPs since 1993. Medicine Lake will continue to be affected by the problems that occur when a lake's watershed has become urbanized. The increased volume and pollutant levels of storm water runoff from the watershed result in a deterioration of lake water quality. This Plan concentrates on the total phosphorus loading to the lake because phosphorus is the nutrient that activates algal growth. A reduction in the phosphorus concentration in a lake is necessary to improve or maintain water transparency. The Medicine Lake watershed was divided into five drainage districts. Each drainage district was evaluated for nutrient removal efficiency under existing conditions which was determined to be the same as the proposed full -development land use conditions. ODMAXPCDOCS%DOCS\210565\1 ES -1 In -lake improvement options and site-specific structural BMPs for each drainage district were evaluated. General BMPs to be implemented throughout the watershed were identified. Recommendations are discussed below: In -Lake Improvement Recommendations Medicine Lake receives more than 40 percent of its annual phosphorus load due to release from its bottom sediments. Areal application of aluminum sulfate (alum) to the lake water can be used as a long-term control of phosphorus release from the lake sediments. This in -lake treatment technique will likely be effective for approximately 10 years, depending upon how well watershed nutrient sources have been reduced. Macrophyte management recommendations are presented to: (1) remove vegetation from beach areas to ensure safe swimming conditions; (2) remove vegetation from public boat landings to insure public access to the lake; (3) improve navigation within the lake through areas containing dense plant beds; (4) improve recreational attributes of the lake; and (5) and reduce current Eurasian watermilfoil, curlyleaf pondweed, and purple loosestrife growth to the greatest extent possible. It is further recommended that boat landings, beach areas, and navigation channels throughout the littoral region be treated with the herbicide Reward during mid-May, late June, and late July. Treatment areas for swimming beaches and boat landings should be based upon the areas in need of treatment to support the intended recreational use of these areas. Repeated treatment is expected to support the intended beneficial uses of the lake and reduce the density of curlyleaf pondweed and Eurasian watermilfoil in the lake. Introduction of a natural predator to help control the purple loosestrife growth along the shore of Medicine Lake is recommended. Two beetle species effectively prey upon purple loosestrife. They include Galerucella pusilla and Galerucella calmariensis. It is recommended that the Commission work with the Minnesota Department of Natural Resources (MDNR) to introduce the beetles in purple loosestrife infested areas of Medicine Lake. Site -Specific Structural BMP Recommendations Specific recommendations for structural BMPs are provided for each of the drainage districts discussed in the report. These recommendations include: ODMA\PCDOCS\DOCS\210565\1 ES -2 1. Plymouth Creek Drainage District Medicine Lake receives approximately more than 30 percent of its annual phosphorus load from Plymouth Creek. Plymouth Creek represents more than 60 percent of the total phosphorus load from the Medicine Lake watershed. One BMP option was identified to significantly reduce the amount of phosphorus that enters the lake. This option invol ve's constructing an alum treatment plant within the Medicine Lake Park area, west of the Medicine Lake west bay, to provide additional treatment of the higher soluble phosphorus concentrations in the storm water runoff from the Plymouth Creek Drainage District. Implementation of this BMP, along with the other recommended BMPs, would improve Medicine Lake water quality and ensure that the water quality goals will be met. This BMP is the only watershed BMP, or combination of BMPs, proposed as part of this study that will significantly improve lake water quality. 2. Ridgedale Creek Drainage District Medicine Lake receives approximately 6 percent of its annual phosphorus load from Ridgedale Creek. The Ridgedale Creek Drainage District represents approximately 12 percent of the total phosphorus load from the Medicine Lake watershed. In addition, Ridgedale Creek represents nearly 70 percent of the total phosphorus load to the eastern half of the Medicine Lake west bay. One BMP option was identified to significantly reduce the amount of phosphorus that enters the lake. This option involves constructing an alum treatment plant adjacent to the wetland on the south side of the Medicine Lake west bay to provide additional treatment of the higher soluble phosphorus concentrations in the stormwater runoff from the Ridgedale Creek Drainage District. Implementation of this BMP, along with the other recommended BMPs, would improve Medicine Lake water quality, especially within the west bay, and ensure that the water quality goals will be met on a more consistent basis. 3. Medicine Lake North Drainage District Medicine Lake receives more than 2 percent of its annual phosphorus load from this drainage district, which represents approximately 5 percent of the total phosphorus load from the Medicine Lake watershed. The existing wet detention ponds in this drainage district provide satisfactory treatment for its watershed. Implementation of additional structural BMPs is not recommended. ODMA\PCDOCS\DOCS\210565\1 $$-3 4. Boat Landing Drainage District Medicine Lake receives less than 2 percent of its annual phosphorus load from this drainage district, which represents approximately 3 percent of the total phosphorus load from the Medicine Lake watershed. The existing wet detention ponds in this drainage district provide adequate treatment for its watershed. Implementation of additional structural BMPs is not recommended. S. Medicine Lake Direct Drainage District Medicine Lake receives approximately 8 percent of its annual phosphorus load from this drainage district, which represents approximately 16 percent of the total phosphorus load from the Medicine Lake watershed. This drainage district receives a relatively small amount of storm water treatment and drains directly to Medicine Lake, either through overland flow or from smaller residential and larger highway storm sewer systems. However, some opportunity for treatment of runoff is currently available. Implementation of additional structural BMPs is recommended, wherever feasible, to control the sediment and phosphorus inputs to the lake. These inputs have created sediment deltas that have accumulated at various points along the lakeshore due to streambank erosion and untreated highway and residential storm water runoff. Geese and other waterfowl within this drainage district also represent a source of phosphorus to Medicine Lake that should be minimized to the maximum practicable extent. The City of Plymouth has been working with the MDNR and a specialist at the University of Minnesota to remove a portion of the goose population from some lakeshore areas each year. This program should gradually diminish the number of geese within the direct watershed over time. However, additional controls, such as city-wide "no feeding" ordinances, habitat modifications, goose barriers, repellents and the use of trained dogs should be considered to keep the goose population in check. General BMP Recommendations 1. Require wet detention for all new or redeveloped properties, where applicable. 2. Adopt and enforce a watershed -wide (or City-wide) ban on the use of phosphorus fertilizers. Continue to educate watershed residents about soil testing and the importance of using phosphorus -free fertilizers. 3. Implement a program to educate watershed residents and lake users on other practices that would reduce pollutants entering the lake. ODMA\PCDOCS\DOCS\210565\1 ES -4 4. Enforce existing ordinances regarding litter and animal waste. 5. Implement street sweeping program that gives priority to the watershed areas within the Medicine Lake Direct Drainage District. 6. Require/encourage vegetated buffer strips between maintained lawns and the lake or detention ponds/wetlands. Providing stormwater alum treatment for both the Plymouth Creek and Ridgedale Creek Drainage Districts, additional wet detention treatment within the Medicine Lake Direct Drainage District, and applying an alum treatment to the lake would help ensure that the Commission's Level I goals are met on a more frequent basis during varying climatic conditions. In addition, the long-term effectiveness of alum treatment depends, largely, upon the extent of watershed BMP implementation to reduce outside nutrient sources. 1 1 I ODMA%PCDocs\Docs\210565\1 ES -5 1 1 6.0 Conclusions and Recommendations This section provides conclusions and recommendations for improving and managing the Medicine Lake watershed to attain the lake water quality goals. 6.1 Conclusions Detailed water quality monitoring data indicate that Medicine Lake is not usually meeting the Commission's water quality goals for Level I water bodies. Full development conditions modeling indicate in an "average" year, the total phosphorus and chlorophyll a concentrations and Secchi disc transparency do not meet the water quality goals. For the most part, the drainage districts in iMedicine Lake remove approximately 44 percent of the total phosphorus that enters the system. However, the Medicine Lake Direct drainage district removes approximately 18 percent of the total phosphorus entering the system. Cost-effective BMPs should be implemented to prevent the degradation of the lake's water quality and mitigate the effect urbanization has on the lake. As shown in Table 8, options are available that would provide effective treatment of stormwater and meet the water quality goals. Additionally, the ireduction in total phosphorus to the lake due to nonstructural BMPs may also assist in reaching the goals. The following summary describes the main conclusions of this study: The analysis of trends in the historical total phosphorus, chlorophyll a, and Secchi disc transparency data indicated that while there is considerable seasonal variability in water quality within the main basin of Medicine Lake and a significant decline in the observed chlorophyll a concentration from 1966 to 1998. However, there has not been a significant trend in either the total phosphorus or Secchi disc transparency data during that time. A 1999 macrophyte survey found a dense macrophyte growth throughout the lake's littoral region. Dense growth areas considered particularly problematic included the south, southwest and northwest portions of the lake. Six Medicine Lake species noted a heavy growth density: Myriophyllum spicatum (Eurasian watermilfoil), Ceratophyllum demersum coontail), Vallisneria americana (wild celery), Chara (muskgrass), Najas (bushy pondweeds and naiads), and Potamogeton spp. (narrowleaf pondweed). j::ODMA\PCDOCS\DOCS\210565\1 66 i Curlyleaf pondweed was found throughout the Medicine Lake littoral zone during the early summer period. Although it occurred in low to moderate density, it is of special concern. As the plants senesce and decay towards the middle of the summer, it could represent a source of internal phosphorus loading to the lake Medicine Lake receives approximately 43 percent of its annual phosphorus load due to release from its bottom sediments (under normal -year drainage conditions). Phosphorus released by the bottom sediments builds up in the hypolimnion and is (1) slowly released into the epilimnion during the course of the summer, and/or (2) delivered to the epilimnion during fall turnover. The study indicates that during an average climatic year implementation of Options 14 and 16 would meet the Commission's Level I goals. However, implementation of Options 6, 8, 9a, 10a, 11 and 17 is also recommended to ensure that the Commission's Level I goals are met on a more frequent basis during varying climatic conditions. Implementation of these options will also alleviate the problems associated with the sediment deltas that have formed at various locations surrounding the lakeshore. While BMPs recommended in this Plan will serve to decrease total suspended solids and phosphorus loads to Medicine Lake, additional nonstructural BMPs should be implemented to protect and improve the water quality in Medicine Lake and ensure that the Commission's water quality goals are consistently met. 6.2 Recommendations In -lake improvement options and site-specific structural BMPs for each drainage district were evaluated for feasibility and cost-effectiveness. It is also assumed that all BMPs currently required by the Commission will be implemented in addition to those recommended below. The following BMP recommendations were developed in the course of this study. While the implementation of structural and in -lake BMPs are usually given priority, it is important to note that source control through the implementation of nonstructural BMPs is crucial to protecting the water quality in Medicine Lake. ODMA\PCDOCS\DOCS\210565\1 67 6.2.1 In -Lake Improvement Recommendations Medicine Lake receives more than 40 percent of its annual phosphorus load due to release from its bottom sediments. Areal application of aluminum sulfate (alum) to the lake water can be used as a long-term control of phosphorus release from the lake sediments. This in -lake treatment technique will likely be effective for approximately ten years, depending upon how well watershed nutrient sources have been reduced. Macrophyte management recommendations are presented to: (1) remove vegetation from beach areas to ensure safe swimming conditions; (2) remove vegetation from public boat landings to insure public access to the lake; (3) improve navigation within the lake through areas containing dense plant beds; (4) improve recreational attributes of the lake; and (5) and reduce current Eurasian watermilfoil, curlyleaf pondweed, and purple loosestrife growth to the greatest extent possible. It is further recommended that boat landings, beach areas, and navigation channels throughout the littoral region be treated with the herbicide Reward during mid-May, late June, and late July. Treatment areas for swimming beaches and boat landings should be based upon the areas in need of treatment to support the intended recreational use of these areas. In general, navigation channels should be 20 to 30 feet wide (see Figure E-1, Volume II). Areas will generally receive a treatment dose of approximately 1 gallon of Reward per 22,000 square feet of lake surface. Repeated treatment is expected to support the intended beneficial uses of the lake and reduce the density of curlyleaf pondweed and Eurasian watermilfoil in the lake. Introduction of a natural predator to help control the purple loosestrife growth along the shore of Medicine Lake is recommended. Two beetle species effectively prey upon purple loosestrife. They include Galerucella pusilla and Galerucella calmariensis. It is recommended that the Commission work with the Minnesota Department of Natural Resources (MDNR) to introduce the beetles in purple loosestrife infested areas of Medicine Lake. 6.2.2 Site -Specific Structural BMP Recommendations Specific recommendations for structural BMPs are provided for each of the drainage districts discussed in the report. These recommendations include: ODMA\PCDOCS\DOCS\210565\1 68 I6.2.2.1 Plymouth Creek Drainage District Medicine Lake receives approximately more than 30 percent of its annual phosphorus load from i Plymouth Creek. Plymouth Creek represents more than 60 percent of the total phosphorus load from the Medicine Lake watershed. One BMP option was identified to significantly reduce the amount of 1 phosphorus that enters the lake. This option involves constructing an alum treatment plant within the Medicine Lake Park area, west of the Medicine Lake west bay, to provide additional treatment of the 1 higher soluble phosphorus concentrations in the stormwater runoff from the Plymouth Creek Drainage District. Implementation of this BMP, along with the other recommended BMPs, would improve Medicine Lake water quality and ensure that the water quality goals will be met. This BMP is the only watershed BMP, or combination of BMPs, proposed as part of this study that will significantly improve the lake water quality. 6.2.2.2Ridgedale Creek Drainage District Medicine Lake receives approximately 6 percent of its annual phosphorus load from Ridgedale Creek. The Ridgedale Creek Drainage District represents approximately 12 percent of the total phosphorus load from the Medicine Lake watershed. In addition, Ridgedale Creek represents nearly 70 percent of the total phosphorus load to the eastern half of the Medicine Lake west bay. One BMP option was identified to significantly reduce the amount of phosphorus that enters the lake. This option involves constructing an alum treatment plant adjacent to the wetland on the south side of the Medicine Lake west bay to provide additional treatment of the higher soluble phosphorus concentrations in the stormwater runoff from the Ridgedale Creek Drainage District. Implementation of this BMP, along with the other recommended BMPs, would improve Medicine Lake water quality, especially within the west bay, and ensure that the water quality goals will be met on a more consistent basis. 6.2.2.3Medicine Lake North Drainage District Medicine Lake receives more than 2 percent of its annual phosphorus load from this drainage district, which represents approximately S percent of the total phosphorus load from the Medicine Lake watershed. The existing wet detention ponds in this drainage district provide satisfactory treatment for its watershed. Implementation of additional structural BMPs is not recommended. 0DMA%PCD0CS\D0CS\210565%1 69 1 6.2.2.4. Boat Landing Drainage District Medicine Lake receives less than 2 percent of its annual phosphorus load from this drainage district. which represents approximately 3 percent of the total phosphorus load from the Medicine Lake watershed. The existing wet detention ponds in this` drainage district provide adequate treatment for its watershed. Implementation of additional structural BMPs is not recommended. 6.2.2.5. Medicine Lake Direct Drainage District Medicine Lake receives approximately 8 percent of its annual phosphorus load from this drainage district, which represents approximately 16 percent of the total phosphorus load from the Medicine Lake watershed. This drainage district receives a relatively small amount of storm water treatment and drains directly to Medicine Lake, either through overland flow or from smaller residential and larger highway storm sewer systems. However, some opportunity for treatment of runoff is currently available. Implementation of additional structural BMPs (BMP Options 6, 8, 9a, 10a, 11 and 17) is recommended, wherever feasible, to control the sediment and phosphorus inputs to the lake. These inputs have created sediment deltas that have accumulated at various points along the lakeshore due to streambank erosion and untreated highway and residential storm water runoff. Geese and other waterfowl within this drainage district also represent a source of phosphorus to Medicine Lake that should be minimized to the maximum practicable extent. The City of Plymouth has been working with the MDNR and a specialist at the University of Minnesota to remove a portion of the goose population from some lakeshore areas each year. This program should gradually diminish the number of geese within the direct watershed over time. However, additional controls, such as city-wide "no feeding" ordinances, habitat modifications, goose barriers, repellents and the use of trained dogs should be considered to keep the goose population in check. 6.3 General BMP Recommendations It is not possible to effectively model the effects of nonstructural BMPs, but studies have shown that they are effective at reducing phosphorus loads. The results of this study have shown that existing wetlands and ponds will be effective at removing large diameter particles and the associated phosphorus from stormwater runoff after completion of proposed development. However, soluble phosphorus and phosphorus associated with extremely small particles may not be effectively removed. Therefore, source control (reduction of particles and phosphorus deposited on site) will be ODMA\PCD0CS\DOCS\210565\1 70 extremely important in the Medicine Lake watershed to reduce the mass of phosphorus in the runoff, and to prevent degradation of the lake. Examples of effective nonstructural BMPs that would be appropriate for the Medicine Lake watershed include: 1. Require wet detention for all new or redeveloped properties, where applicable. Skimming devices to trap floating material should also be included at the outlet of all wet detention ponds. This has been accomplished with implementation of the Commission's Water Quality Management Policy, but should be strictly followed to minimize variances as much as possible. 2. Adopt and enforce a watershed -wide (or City-wide) ban on the use of phosphorus fertilizers. Continue to educate watershed residents about soil testing and the importance of using phosphorus -free fertilizers. As discussed in Section 5.0, exceptions to such a ban would be granted in cases where a resident was able to demonstrate, by means of soil analyses, that phosphorus was required. This ban should also include lawn fertilizer used in City Parks. 3. Implement a program to educate watershed residents and lake users on proper handling of yard fertilizers and wastes, pet wastes, soaps and detergents, and other practices that would reduce pollutants entering the lake. 4. Encourage industrial/commercial areas to institute good housekeeping practices, including appropriate disposal of yard wastes, appropriate disposal of trash and debris, appropriate storage and handling of soil and gravel stockpiles. 5. Enact new ordinances, or revise, and enforce existing ordinances regarding litter and animal waste. This enforcement should concentrate in areas where the depositing of debris would likely enter the stormwater system and enter the lake (i.e., direct drainage district and other areas where stormwater does not drain to wet detention before entering Medicine Lake). 6. Implement street sweeping program that gives priority to the watershed areas within the Medicine Lake Direct Drainage District. 7. Require vegetated buffers between yards and the shore of Medicine Lake. Vegetated buffers are effective at trapping suspended solids and nutrients from runoff. Requiring/encouraging vegetated buffers between yards and the lake will reduce the amount of phosphorus from yard 0DMA\PCDOCS\DOCS\210565\1 71 runoff, and will prevent shoreline erosion. Vegetated buffers also discourage waterfowl from nesting and feeding on yards adjacent to the lake. Lakescaping for Wildlife and Water Quality (Henderson et al., 1999) describes beneficial natural plants for shoreline landscaping; copies of this book could be kept on hand at the city offices for use by lakeshore homeowners. Vegetated buffers need not be overgrown and weedy; this book has many examples of attractively landscaped shoreline buffers. 8. Continue to discourage the feeding of waterfowl at shoreline areas around Medicine Lake and upstream lakes and ponds. Waterfowl feces can add a significant amount of dissolved phosphorus to a lake or pond. Shoreline areas provide essential nesting and feeding habitat for some waterfowl, however, the habit of leaving bread scraps and other food for waterfowl encourages a large number to congregate and nest. This happens most often at shoreline parks, where large numbers of people and large expanses of short grass attract unusually large numbers of waterfowl. Continuing to prohibit the feeding of waterfowl on public shorelands may reduce the number of waterfowl congregating on the lake. Providing stormwater alum treatment for the Plymouth Creek Drainage District, additional wet detention treatment within the Medicine Lake Direct Drainage District, and applying an alum treatment to the lake would help ensure that the Commission's Level I goals are met on a more frequent basis during varying climatic conditions. In addition, the long-term effectiveness of alum treatment depends, largely, upon the extent of watershed BMP implementation to reduce outside nutrient sources. f ODMA\PCDOCS\DOCS\210565\1 72 Table Lake Improvement Options, Based on Average Year Conditions Medicine Lake Watershed and Lake Management Plan ODM A\PCDOCS\DOCS\210564\ I Total Reduction Predicted Lake QualityParameters' Chlorophyll a TransparencyOptionDescription Option Number Capital Cost Annual 03M Cost Annualized Cost' Phosphorus Loading of to Lake(lbs) to Lake µg/L) µg/L) feet) Existing 9,287 44 16 5.0 Construct Wet Detention Pond 1 6,802,700 54,420 438,000 9,174 1% 44 16 5.0 within Medicine Lake Park area and Direct Flows from Plymouth Creek and BC43B through Pond Construct Wet Detention Ponds for 2 380,000 3,040 24,500 9,256 1% 44 16 5.0 Subwatershed DC47 Raise Outlet and Excavate 3 151,000 1,210 9,730 9,221 1% 44 16 5.0 Additional Storage Volume within Pond BC -P8 Construct Wet Detention Pond 4 378,300 3,030 24,400 9,280 1% 44 16 5.0 downstream of Subwatershed BC78A Construct Wet Detention Pond 5 472,100 3,780 30,400 9,280 1% 44 16 5.0 within Subwatershed BC77A Construct Wet Detention Pond for 6 10,800 86 700 9,286 1% 44 16 5.0 Subwatershed BC94132 Route Runoff from Subwatershed 7 57,270 458 3,690 9,278 1% 44 16 5.0 BC91 Into Wet Detention Pond for Subwatershed BC94C Construct Wet Detention Pond for 8 0 347 347 9,283 1% 44 16 5.0 Subwatershed BC94131 Construct Wet Detention Pond at 9 151,260 1,210 9,740 9,266 1% 44 16 5.0 13C -P40 Location and Reroute Flows from Subwatershed BC94 to a Larger Wet Detention Pond for Subwatershed BC92 Reroute Flows from Subwatershed 9a 90,200 722 6,400 9,274 1% 44 16 5.0 BC94 to a Larger Wet Detention Pond for Subwatershed BC92' Construct Wet D3tentior Ponds for 10 1,256,960 10,060 80,970 9,200 1% 44 16 5.0 Subwatersheds BC98, BC98A and BC98B Construct a Wet Detention Pond 10a 272,540 2,180 19,500 9,269 1% 44 16 5.0 for Subwatersheds BC98, BC98A and BC98B' ODM A\PCDOCS\DOCS\210564\ I Option Description Option Capital Annual Annualized Total Phosphorus Reduction Predicted Lake QualityParameters' Number Cost O&M Cost Cost Loading of TP TP Chloro ph' a Transparency to Lake lbs to Lake pg/L)' pg/L)' feet)' Construct Wet Detention Pond for Subwatershed BC107' 11 347,950 2,780 22,410 9,254 1% 44 16 5.0 Construct Wet Detention Pond at BC -P40 Location 12 46,320 371 2,980 9,282 1% 44 16 5.0 Plymouth Creek Stormwater Alum Treatment Plant (Design Flow = 30 13 2,276,500 136,900 281,320 7,308 21% 39 13 5.5 cis Plymouth Creek Stormwater Alum 14 1,812,500 97,500 212,490 7,614 18% 40 14 5.4TreatmentPlant (Design Flow = 20 cis Ridgedale Creek Stormwater Alum 15 919,500 38,450 96,780 8,913 4% 43 15 5,1TreatmentPlant (Design Flow = 5 cis In -Lake Alum Treatment' 16 1005900$0 137 000 6 275 32% 36 12 5.9ReducingCurrentGooseLoadings17102,500 1,000 7,500 9,200 1% 44 16 5.0by75% In -Lake Herbicide Treatment 18 0 1,000 1,000 9,287 1% 44 16 5.0Options1and2197,182,700 57,460 513,000 9,164 1% 44 16 5.0Options1, 2 and 3 20 7333700 58,670 524,000 9,118 2% 44 16 5.0Options14and16212,818,400 97,500 276,000 4,602 50% 30 9.0 6.9ImplementationofAllNecessary224,319,000' 139,000' 413,000' 9,169 1% 44 16 5.0BMPstoReachGoalsinUpstream Lakes Options 6, 8, 9, 10, 11, 14, 16, 17 23 4,687,900 113,980 411,000 4,369 53% 29 8.6 7,1and18 Options 6, 8, 9a, t0a, 11, 14, 16, 24 3,642,400 105,620 337,000 4,386 53% 29 8.6 7.117and18 Assumes 50 years with a 6.0% interest rate.
