Adults are 1/4 to 1 1/2 inches long and have D- shaped shells with alternating yellow and brownish colored stripes. Female zebra mussels can produce 100,000- 500,000 eggs per year. These develop into microscopic, free-living larvae (called veligers) that begin to form shells. After two-three weeks, the microscopic veligers start to settle and attach to any firm surface using "byssal threads". It is the only freshwater mussel that can attach to objects. They are native to Eastern Europe and Western Russia and were brought over to the Great Lakes in ballast water of freighters. Populations of zebra mussels were discovered in the Great Lakes about 1988. Impacts: Zebra mussels can cause problems for lakeshore residents and recreationists. Homeowners that take lake water to water lawns can have their intakes clogged. Mussels may attach to motors and possibly clog cooling water areas. Shells can cause cuts and scrapes if they grow large enough on rocks, swim rafts and ladders. Anglers may lose tackle as the shells can cut fishing line. Zebra mussels can also attach to native mussels, killing them. Zebra mussels filter plankton from the surrounding water. This filtering can increase water clarity, which might cause more aquatic vegetation to grow at deeper depths and more dense stands. If a lake has high numbers of mussels over large areas, this filter feeding could impact the food chain, reducing food for larval fish. Many zebra mussels attached to a native mussel. Status: They have spread throughout the Great Lakes and the Mississippi River from Brainerd downstream, and are now in other rivers and inland lakes. They are established in Minnesota and were first found in the Duluth/Superior Harbor in 1989. The 7 OF list provides details of current infestations. Diving ducks, freshwater drum (sheepshead), and other fish eat zebra mussels, but will not significantly control them. Means of spread: Mussels attach to boats, nets, docks, swim platforms, boat lifts, and can be moved on any of these objects. They also can attach to aquatic plants, making it critical to remove all aquatic vegetation before leaving a lake. Microscopic larvae may be carried in water contained in bait buckets, bilges or any other water moved from an infested lake or river. Where to look: Examine boat hulls, swimming platforms, docks, aquatic plants, wood and other objects along shorelines of lakes and rivers. Join in the and report your efforts each year. Regulatory Classification: It is a pro hib i t e d invasive_specleg (DNR), which means import, possession, transport, and introduction into the wild is prohibited.

Sponsored five separate DNR Training sessions to educate a total of 61 Volunteers to work at the South Lotus Lake Park boat ramp this summer. - Worked nearly 700 hours at the Lotus Lake boat ramp, performing boat inspections and educating boaters about AIS. - Inspected 917 boats, many of which were arriving from infested waters, and many of which had hull plugs in place and/or water on board. - Developed a website to keep interested citizens up to date on Lotus Lake happenings: o .Ito./ - In addition to the existing Clean Water Organization website: o http• / /Iotuslakecleanwater.corn - Held four public informational meetings at the Chanhassen Public Library to inform the community about the threat of AIS. - Held several meetings with City leaders to inform them about AIS issues. - Presented before the Parks & Recreation Commission concerning AIS and Lotus Lake. 2011 Findinp Of the 917 boats that were inspected at Lotus Lake, we found: 138 boats (15% ) were coming from infested waters 0 54 fishing boats (38 %) 0 50 runabouts (35 %) o 23 ski boats (17 %) 0 7 jet skis (5 %) a 2 kayaks (2 %) o 2 canoes (2 %) - 122 (13 %) of boats were arriving with hull plugs in place and /or water on board * * It is important to note that these figures do not include boats that launched before or after park hours Page 20 Lotus Lake Zebra Mussel Inspection Checklist Objective: Congratulations, you are part of a growing number of boat inspectors dedicated to stopping the spread of AIS (Aquatic Invasive Species) in Lotus Lake, you have gone through the DNR training, and are now ready to start inspecting boats. This checklist is designed to be sure that each inspector consistently inspects boats in a manner that maximizes our efforts and minimizes the possibility of zebra mussels entering our lakes while following the procedures outlined in the DNR manual. Before you begin: You will find everything you need for your shift in the storage box anchored at the top of the boat landing. The storage box is locked, and the combination is: [omitted]. In the box are a table and chairs, umbrellas, flashlights, buckets, literature to hand out, clipboards and the checklist you will be filling out as you inspect boats. If you are the first inspector of the day, you'll need to set up the table and chair(s) on the road at the top of the street. You'll also want to lay out the literature that you will be passing out to boaters as they enter the landing. Make sure you have the clipboard with several pages of the checklist and questionnaire that you will be filling out for each boat that passes through the landing. If this is your I" of 2n time conducting inspections, you may want to briefly re -read the procedures in the volunteer manual, particularly the parts on the inspection process. When a boat enters the landing area As the car slows to a stop, approach the driver's side window and introduce yourself, explain that you are working with the DNR to stop the spread of invasive species and, in particular, zebra mussels. After asking the questions on the survey, let the driver know that you will be conducting a quick inspection of the boat and trailer (proceed to conducting inspection as outlined in the training and in the manual). Things to remember: - Be friendly (but firm) and educate the boater as you go — demonstrate how they can conduct self - inspections. - Use the ID cards and literature to highlight what you are looking for on the boat and trailer. - Follow the procedure in the volunteer manual including making it as quick and painless as possible. - Have some fun and stay positive — the boaters will be taking cues from your demeanor — let them know this is a great thing for Minnesota lakes! If you encounter an `angry' or combative boater: - While this will be a rare occurrence, calmly let them know you are a volunteer working to protect Lotus Lake. If they insist on launching without an inspection and you think they may be transporting water or other prohibited items, follow the procedure in the manual including calling a conservation officer. At the end of your shift, please be sure to put things back into the storage boa, and lock it. THANK YOU FOR HELPING TO PROTECT LOTUS LAKE` Page 21 REQUEST FOR PROPOSALS Minnesota Department of Natural Resources Project Overview This project involves the preparation of a report required by Laws of Minnesota 2011, Chapter 107, Section 106. By January 15, 2012, the commissioner of natural resources shall report to the house of'representatives and senate committees with jurisdiction over environment and natural resources policy and finance on the long -term funding needed to implement and enforce Minnesota Statutes, chapter 84D, including recommendations on the appropriate amount of the watercraft surcharge. Goal The goal of this project is to identify options and costs for implementing and enforcing statewide measures to prevent the spread of aquatic invasive species (AIS). Tasks Prepare a report that evaluates the long -term funding needed to implement and enforce provisions in Minnesota Statutes, Chapter 841), that are specifically related to watercraft inspections, decontamination, transport, launching, and removal and confinement to prevent the spread of AIS. The scope of this request for proposals is limited to identifying options and costs for implementing and enforcing a statewide AIS prevention program. Identifying funding sources to implement any of the options is not within the scope of the project. Evaluate the feasibility, advantages and disadvantages, potential limitations and effectiveness, staffing and infrastructure requirements, potential for privatizing and estimated costs to implement AIS prevention programs in Minnesota on a statewide basis using concepts described in A, B, and C below. A. A sticker or tagging system that would allow watercraft: 1. To go from uninfested waters to other uninfested waters without a mandatory inspection requirement. 2. To go from uninfested waters to infested waters without a mandatory inspection requirement. 3. To go from infested waters and return to the same infested water body without a mandatory inspection requirement. 4. To go from infested waters to uninfested waters or to another infested waters with different AIS after a mandatory inspection. 5. To go from Zebra mussel infested waters: a. To other Zebra mussel infested waters without a mandatory inspection. b. To waters not infested with Zebra mussels after a mandatory inspection. B. A mandatory inspection requirement for all watercraft prior to launching on Public Waters (infested or uninfested). The evaluation should include cost efficient options for controlling Rev 07/11 Page 22 public and private accesses with radio - frequency identification (RFID) or other technologies to verify compliance with inspection requirements. C. A mandatory inspection program for all watercraft leaving infested waters. Options should include an evaluation of costs associated with inspection of all infested water, Zebra mussel infested water, and high -use Zebra mussel infected waters. "Inspect" as defined by M.S. 84D.01 may include decontamination or treatments to prevent the spread of AIS. Estimated costs for inspection and decontamination requirements must include: The number of inspection facilities needed for a statewide program and the general location of inspection facilities necessary to minimize the time required to complete the inspection before or after using a public or private water access. • The potential for consolidated inspection locations within a reasonable distance of multiple water bodies /launch sites in order to minimize costs related to inspection facilities and staffing. • Infrastructure, technology, and staffing requirements to establish a statewide inspection program. • The use of private companies and local governments for inspection services. • The use of stationary and portable decontamination equipment. • All other factors necessary to implement a statewide AIS inspection and decontamination program. • Research AIS prevention programs proven to be effective in other states or countries that do not include concepts 'listed in A.. B, or C. The contractor will work closely with department personnel and will prepare draft outlines and drafts of the report for review and approval by the department. A draft report is due by December 15, 2011 and the final report is due on January 12, 2012. Discussion of possible additional work within the scope of the RFP will be done as the report nears completion. The contract will begin on the date stated in the contract or upon full execution of the contract, whichever is later, and shall remain in effect until April 20, 2012.

Page 28 Pl�nn4t Q &A About the Watercraft and Bait Container Draining Laws in Minnesota Revised June 9, 2011 Q. What does the 2011 version of the "Drain Plug" law require? A. The 2010 Minnesota Legislature passed a new boat draining law that took effect on July 1, 2010. This law was created to reduce the risk of boaters spreading fish diseases (e.g., VHS) and life stages of aquatic invasive species (e.g., spiny waterfleas and zebra mussel larvae) that are not easily observed or detectable in water and could be transported to other waters. Often new infestations are not detected immediately, so there are risks of transporting water from all waters including from those in other states. In 2011, the law was modified (Minnesota Statutes. 84D.10, Subd. 4) and as of May 28, 2011 it currently states, (a) When leaving waters of the state a person must drain water - related equipment holding water and live wells and bilges by removing the drain plug before transporting the water - related equipment off the water access site or riparian property. (b) Drain plugs, bailers, valves, or other devices used to control the draining of water from ballast tanks, bilges, and live wells must be removed or opened while transporting water - related equipment. (c) Emergency response vehicles and equipment may be transported on a public road with the drain plug or other similar device replaced only after all water has been drained from the equipment upon leaving the water body. (d) Portable bait containers used by licensed aquatic farms and marine sanitary systems are exempt from this subdivision. (e) A person must not dispose of bait in waters of the state. Q. What do people need to do with bait containers? A. The law requires all water to be drained from portable bait containers before leaving the water access including from bait containers that have not been placed in lake or river water. Q. How can I comply with draining portable bait containers when portaging from one lake to another? A. If you are portaging a canoe or other watercraft, you will need to drain the water from the bait container on land where it won't drain into any water body and refill the bait container with water from the new water body. Q. After draining water from bait containers can I keep unused bait? A. Anglers can keep unused bait after draining their bait containers. You can replace the water in portable bait containers with tap or bottled water before transporting the bait. Some angling related businesses have developed products to help transfer bait from a bait container in the boat to a container in a motor vehicle without the water. Q. How do people need to dispose of unused, unwanted bait? A. As of July 1, 2010, state law prohibits dumping unused bait into waters of the state, Dumping bait on the ground is considered littering. Therefore, unwanted live bait should be placed in the trash, disposal bins, or compost bins where you are allowed to place such material. Q. Do drain plugs need to be removed from pontoons on pontoon boats? A. No, they are air holding compartments and not intended to hold water. Plugs do not need to be removed from pontoons when they are transported, unless they are damaged and contain water. Page 29 Q. How long do the drain plugs need to be removed? A. D[8|O plugs must be removed and water draining valves or devices in watercraft must be open the entire time that a watercraft is being transported. The one exception kS for emergency response vehicles, such as boats used by law enforcement officers, only after the boats are drained. Q. What should personal watercraft operators do to expel water from the impellers/? A. Personal watercraft operators should turn on the engine for 5 to 10 seconds after remov the watercraft from the water to expel the water and organisms inside the impeller. Q. What if a wakeboard boat does not have a00aster drain plug for the ballast tank? A. The baUaot ' oforxvmkeboand and ski boats vary depending upon the manufacturer. Some are designed to pump out all the water in the system and others require the operator to |hft the bags � ballast �to�nmur8@Uth�xv�ter v |�dna|n�d �u� The tanks should be pumped until no water ia expelled while the boat is|n the water. Some have pumps that can be used out nf the water. Boaters should consult with a boat dealer who sells their brand of boat for specific draining procedures. Q. Are there exce m�r��t�a�di�� �� difficult A. The Dy�R is awar tho1 many different drain plug locat and ntvkeo exei, as well as assorted draining avetenlofor |ivexva||a and ballast tanks. Even with those differences, all boats are subject ' i | i the | t m||ovx waivers for specific boats or of to1ho\avvandthenearenoprovonn� n e avv o ^ boats. In some oituationm, permits may be issued to transport water from infested water for larger inboard orinbnand/outboord boats to avoid discharging bilge vvotar into the lake that contains oil or other liquids that are illegal to discharge into lakes and rivers. Boaters with unique drain plug locations or draining situations are encouraged boconsul marine dealer ora local boat repair shop to/ situations by installing alternate drain plugs c drain plug stv|es, ranging from about $4 to $ available at marine dealers. These are na|aU` install by the owner or marine dealer. Many of the drain plug systems are desi for removal of the plug from the outside of the transom (see photoe). which may make removing the plug and reinstalling it at a water access easier than from the interior of the boat. Note The DNR does not endorse any particular st Or brands 0f drain plugs. Q. Who can answer further questions about these regulations and enforcement? A.

Clean all recreational equipment. If you are a water recreation ist— boater, angler, water - skier, sailor, or canoeist —there are some important things you can do to prevent the transport of invasive species from one lake or river to another. In Minnesota it is illegal to transport prohibited invasive species View a short video Faim about what you can do to stop the spread of aquatic hitchhikers. MINNESOTA It is unlawful to: • transport aquatic plants (see: exceptions in statute round goby, zebra mussels, or other prohibited species • launch a watercraft with aquatic plants, zebra mussels, or prohibited /regulated invasive species attached • transport water from designated infested waters • transport water from lakes or rivers in boats, livewells, and bait containers • transport watercraft and water - related equipment that hold water from a water access site or riparian property without draining them by removing the drain plug and opening water- draining devices REQUIRED ACTIONS Inspect all watercraft, trailers, and water - related equipment; remove any visible aquatic plants, zebra mussels, and other prohibited invasives species before leaving any water access. �= I Page 31 Dispose of unwanted bait in the trash. It is illegal to release live bait into a waterbody or release aquatic animals from one waterbody into another. RECOMMENDED ACTIONS Drain water from boat, livewell, bilge, impellor, bait containers and other equipment holding water before leaving any water access. If you want to keep your live bait after draining bait containers, you must replace water in bait containers with tap or spring water. Some species are small and difficult to see at the access, so to remove or kill them before transporting your watercraft to other waters, either: ■ ■ Rinse your boat and boating equipment with hot tap water (over 120 F); or Spray your boat and trailer with a high - pressure sprayer. (The hot water sprayers at a car wash can be used); or Dry your boat and equipment for at least 5 days. REPORT new sightings of aquatic invasive species. If you suspect a new infestation of an invasive plant or animal, save a specimen and report it to a local natural resource office. Recommended for the following activities: • Shore and fly- fishing: Remove aquatic plants, animals, and mud from waders and hip boots. Drain water from bait containers. • Personal watercraft: Avoid running engine through aquatic plants. Run engine for 5 -10 seconds on the trailer to blow out excess water and vegetation Page 32 from internal drive, then turn off engine. Remove aquatic plants and animals from water intake grate, steering nozzle, watercraft hull, and trailer. • Sailing: Remove aquatic plants and animals from hull, centerboard or bilgeboard wells, rudderpost area, and trailer. ■ Scuba diving: Remove aquatic plants, animals, and mud from equipment. Drain water from buoyancy compensator (bc), regulator, tank boot, and other containers.

Nothing in the L &WCF requirements forbids a grant recipient from setting and enforcing operating hours to protect or properly manage the funded facility so long as the facility is open for public use at reasonable hours and times of the year. This is consistent with my August 26, 2011 letter to Todd Hoffman, the Park and Recreation Director for the City of Chanhassen (enclosed). In that letter, I said "[I]nstalling an access gate on the site would be allowable if it were necessary to protect recreation in the park itself - for example, if overnight vandalism was a problem." If you have any further questions about the L &WCF grant program, please contact me.

On all following pages of this document, the comments in red are Todd Hoffinan's. I've added a response to each of your questions below: - There was no issue with closing or gating South Lotus Lake Park during non - operating hours. That is correct. If the City determines there is a need to enforce non - operating hours they would be allowed to erect a gate at the entrance. That at a park such as Lake Ann Park, if the City wanted to enforce park hours, either the entire park could be closed during non -park hours, or just the boat launch, or playground, or other section could be closed, at the City's discretion. A grant recipient may set hours of operation for individual facilities within the park for safety reasons, such as closing a swimming pool unless lifeguards are present. Facilities within a park may be declared obsolete and permanently closed if the sponsor can demonstrate that its recreation needs have changed and the facility is no longer needed for outdoor recreation. That the key to closing or gating a park, boat access, etc., was to not selectively apply some type of exclusion. If the park or boat ramp is open, it is open for all people, and if it's closed, it's closed for all people. Nothing in the L &WCF requirements forbids a grant recipient from setting and enforcing operating hours to protect or properly manage the funded facility so long as the facility is open for public use at reasonable hours and times of the year.

I talked with Todd yesterday to ensure this was his understanding as well. He agreed that it was. Joe From: Laurie Susla [mailto:lcsusla @mchsi.com] Sent: Sunday, October 16, 20112:38 PM To: Hiller, Joe H (DNR) Subject: South Lotus Lake Park Hello Mr. Hiller, I'm sorry to bother you again on the question of South Lotus Lake Park, but there seem to be some inconsistencies between what Todd Hoffman at the City of Chanhassen believes regarding enforcing park hours, and your letter to me on the same issue. I've highlighted in red the section of Todd's email to me (see below) that is particularly confusing. It seems to directly contradict your October 14th letter on this issue. We know that: - There was a gate and gate house at South Lotus Lake Park that closed during non -park hours from approximately 1986 to 1997. That gate & house were removed in 1997 because the City of Chanhassen no longer felt it important to have them there, not due to a request by the DNR. - There is currently a gate at Minnewashta Regional Park, another Chanhassen park, controlled by Carver County, which is locked closed during non -park hours. - All 21 Three Rivers Parks have automated gates that close after park hours. So, it would seem as though using a gate to enforce park hours is neither illegal nor contradictory to L &WCF code. As I stated in my earlier letter to you, we are not asking the City of Chanhassen to necessarily gate the park, we are simply asking that they enforce the current operating hours. Since a gate is the least expensive way to do this, I'm sure this topic will come up at the October 29th meeting. Therefore, we would very much appreciate your clarification on Todd's highlighted comment below. Did you in fact tell Todd that "a gate would not be allowed during the posted park hours as well as before or after the 10/24/2011 Page 36 posted park hours ", or was there some confusion on his part? We would like our meeting with the City to be as productive as possible, and degrading this question into a "he said, she said" situation would be the opposite of productive. Thank you Joe for clarifying this issue, and thank you for all the time you've spent on this matter. Please call me if you have any questions.

The transport of ballast water from Europe was believed to be the cause of the introduction of mussels into the Great Lakes. Another species of mussels, quagga mussels (Dreissena bugensis), closely related to zebra mussels, were first reported in Lake Erie in 1989, but they were not identified as a distinct species until 1991. Although the quagga and zebra mussels were introduced to the United States within a difference of a few years, the zebra mussel was the first species to spread in prolific numbers at astounding speeds and affect the waters of the Great Lakes. These two closely related species (known as dreissenid mussels) can cause significant negative impacts to aquatic ecosystems, recreational opportunities, economics, and water conveyance systems. Although the waterbodies in the Riley- Purgatory -Bluff Creek Watershed (Watershed) have not yet experienced infestation by dreissinid mussels, but may be under imminent threat of infestation by dreissenid mussels due to the spread of mussels in the surroundings waterbodies. This memorandum documents an overview of dreissenid mussel species, environmental factors that affect their growth and survival, and economic, environmental and water quality impacts of mussels. Furthermore, a discussion of transfer mechanisms of mussels from infested water to uninfested waters and monitoring and mussel control mechanisms with proactive and reactive strategies is provided. The overall goal of this memorandum is to provide a basic understanding of impacts of dreissenid mussels and preliminary guidance for assessing the degree to which any waterbody in the Riley- Purgatory -Bluff Creek Watershed can be at risk of becoming colonized by dreissenid mussels. A key next step for determination of mussel colonization potential will be to conduct an evaluation of colonization potential (based on the ranges of key physical and chemical characteristics) for various waterbodies in the Watershed. There are a number of research efforts currently Page 39 BACKGROUND AND EFFECTS OF DREISSENID MUSSELS IN WATERBODIES- PRELIMINARY GUIDANCE FOR THE RILEY- PURGATORY -BLUFF CREEK WATERSHED underway. Information on these efforts, a number of which CH2M HILL is involved, can be provided should the District be interested. This memorandum is intended to foster an understanding of the potential risks of mussel colonization in the Watershed and provide necessary next steps to start developing collaborative efforts among stakeholders to delay the arrival of mussels. Further, guidance is provided on proactive and reactive strategies and control mechanisms to avoid the spread and control and reduce the size of mussel infestations. Background Both the zebra and the quagga mussels are small mussels found only in freshwater. They look very similar to each other. These freshwater bivalves have two hinged shells (or valves) that surround the body. The shells are smooth or shallowly ridged and can be variable in color, from solid light to dark brown, or have alternating dark and light concentric stripes. At various stages of life, mussels range in size from microscopic to the size of a fingernail and can attach to most surfaces. These mussels are usually less than 2 inches in length. In new populations, most mussels are young and therefore very small (under 1 /4 -inch long). They breathe and feed by inhaling water and passing it over their gills, removing oxygen and plankton from water. Both species have incredibly high filtration rates; an adult mussel is capable of filtering almost one liter of water per day. Zebra Mussel Figure 1 Zebra mussel and quagga mussel Environmental Factors Affecting Growth and Survival of Mussels Quagga and zebra mussels do well under certain ranges of environmental conditions and poorly outside of those ranges. Some environmental factors that can affect mussels include water temperature, flow, pH, calcium, salinity, nutrients (and phytoplankton levels), turbidity, and substrate. Some factors such as temperature, calcium, flow, and dissolved oxygen play a crucial role in mussel survival, growth, and reproduction (Table 1). For example, mussel abundances tend to peak at water temperatures that are optimal for growth and reproduction. Outside of the optimal temperature range, growth and reproduction rates slow down with a resulting decline in mussel production. High and low temperature extremes are very limiting to the mussels, with no growth or reproduction occurring at those temperatures. In fact, high temperatures in excess of 30 °C can be lethal to mussels (Cohen, 2007). An understanding of mussel responses to specific environmental factors could potentially be leveraged in developing and implementing mussel control and /or management strategies based on targeting potential vulnerabilities of dreissenid mussels to specific environmental factors or combinations of environmental factors. Page 40 BACKGROUND AND EFFECTS OF DREISSENID MUSSELS IN WATERBODIES - PRELIMINARY GUIDANCE FOR THE RILEY- PURGATORY -BLUFF CREEK WATERSHED Although both of these species have many similarities in their life cycle and adaptation to environmental conditions, they differ in important ways in some of their activities, habitat preferences and tolerances. Zebra mussels typically are known to heavily colonize hard substrates while quaggas colonize both hard and soft substrates. It appears as though quaggas colonize water bodies at greater depths than zebra mussels, infesting a wider range of habitats. In locations where both mussels exist, the quagga mussels appear to compete with the zebra mussels, eventually replacing them. Table 1 lists differences in quagga mussel and zebra mussel activities under various limnological variables. This table also illustrates the shifts in colonization patterns between quagga mussels and zebra mussels in Lake Michigan. In general, both quagga and zebra mussels have somewhat similar responses and tolerances to environmental variables, with some notable differences in preferred and reproductive water temperatures and depth requirements (Table 1). The environmental preferences of mussels presented in Table 1 will form the basis for defining and assessing the potential of District's water bodies to dreissenid mussel colonization and population growth. Additional parameter for assessing level of infestation can include total hardness, alkalinity, Secchi depth, total phosphorus and total nitrogen.

Figure 2 shows the potential transport mechanisms for adult mussels or smaller mussels or veligers from one waterbody to another. The top panel of Figure 2 shows the transport mechanism of adult mussels and veligers from source waterbody to receiving waterbody. The bottom panel in this figure shows transfer of mussels and veligers from a mussel infested waterbody to an uninfested waterbody. Page 41 BACKGROUND AND EFFECTS OF DREISSENID MUSSELS IN WATERBODIES - PRELIMINARY GUIDANCE FOR THE RILEY - PURGATORY -BLUFF CREEK WATERSHED Although adult mussels can survive for a week or more in cool, moist, and shaded conditions, veligers cannot survive out of water very long. Veligers will desiccate quickly (within less than an hour to a few hours, depending on size) without water. Boats that have been in the water for more than 1 or 2 days may have mussels attached to their hulls, anchors and chains, trailers, equipment, and engine drive units. Major transport paths include the following: • Recreational boaters, anglers, and commercial barges not thoroughly cleaned after docking in infested waters for an extended period of time • Live wells, in bilges, within the engine cooling systems, and in bait and collection buckets that have not been drained or decontaminated • Aquatic plants infested by mussels Many of the District's lakes are used for a variety of recreational purposes, including swimming, fishing, boating, water skiing, and canoeing. The potential mechanism for the transport of mussels to the District's lakes could be through recreational activities. Recreational boating has a high potential for transferring dreissenid mussels to various waterbodies.

Major ecological changes have occurred since zebra mussels invaded the Saginaw Bay in 1990 (Nalepa et al. 1995). Since its invasion, this non - indigenous species has demonstrated a unique ability to change a lake's trophic state, indeed the overall ecosystem structure and function, due to its capability to filter huge amount of suspended particles (Sprung and Rose 1988, Reeders et al. 1989, Reeders and bij de Vaate 1992, Fanslow et al. 1995), variable feeding patterns (Walz 1978a, Sprung and Rose 1988), high reproductive rates (Walz 1978b), and competitive advantage for food and habitat (Walt 1978a, 1978c). Zebra mussels have also demonstrated a tolerance for a relatively wide range of limnological conditions (Lewandowski and Ejsmont - karabin 1983, Sprung and Rose 1988, Leach 1993, Karatayev and Burlakova 1996, Hincks and Mackie 1997). These attributes have allowed zebra mussel populations to impact the aquatic ecosystem by altering food web dynamics, rate of sedimentation, and contaminant cycling (Ramcharan et al. 1992, Miller and Ignacio 1994). Impacts of Mussels on Ecology and Water Quality Dreissenid mussels are prodigious water filterers and they remove substantial amounts of phytoplankton, zooplankton and suspended particulates from the water, which reduces the food sources for zooplankton and small fish and alters the food web. Changes in ecology and water quality can occur due to complex interactions of aquatic organisms and the chemical composition of water. For example, changes in phytoplankton community, water clarity, and nutrient concentrations can cause perturbations in the ecosystem in a number of ways, including: • Nonselective filtration (Maclsaac,1996; James et al.,1997 ; Makarewicz et al., 1993) • Selective rejection of certain types of ingested algae as pseudofeces (Vanderploeg et al., 2001) • Filtration of herbivorous zooplankton (Shevtsova et al., 1986 ; Maclsaac et al., 1991) • Removal of suspended solids from the water column, thus affecting water clarity and light penetration (MacIsaac et al., 1992; Holland, 1993; Fahnenstiel et al., 1995b) • Excretion of soluble forms of nutrients by mussels (Heath et al., 1995; Mellina et al., 1995; Nalepa et al., 1991; Quigley et al., 1993; James et al., 1997; Effler et al., 1997; Canale and Chapra, 2002) • Changes in the quality of surface sediments by deposition of large quantities of organic carbon and nutrient -rich feces and pseudofeces (Stewart et al., 1998) Observations on zebra mussel impacts in large water bodies included the following: • Increases in water clarity ( Fahnenstiel et al., 1995a; Lowe and Pillsbury, 1995; Skubinna et al., 1995) • Alteration in nutrient levels (Johengen et al., 1995, Fahnenstiel et al., 1995a; Heath et al., 1995) • Declines in chlorophyll a concentrations ( Fahnenstiel et al.,1995b ; Nalepa et al., 1999) • Shifts in primary production from pelagic to benthic compartments (Lowe and Pillsbury, 1995; Pillsbury et al., 2002) Page 43 BACKGROUND AND EFFECTS OF DREISSENID MUSSELS IN WATERBODIES -PRELIMINARY GUIDANCE FOR THE RILEY - PURGATORY -BLUFF CREEK WATERSHED • Increases total organic carbon (TOC) in water column • An increase in the areal extent of submerged macrophytes (Fahnenstiel et al., 1995b; Skubinna et al., 1995; Pillsbury et al., 2002) Impacts of Mussels on Recreation Recreation -based industries and activities are also affected by dreissenid infestations since they attach to docks, breakwalls, buoys, boats and they create colonies on beaches. Mussels can also negatively impact recreational boating by colonizing the hulls, engines and steering components of boats and other recreational equipment, and can damage boat motors and restrict cooling. Mussels are known to foul many types of surfaces including docked boats, outboard motors, fishing gear, and beaches, all of which can adversely affect recreational activities such as fishing, boating, swimming, and active and passive recreation. Impacts of Mussels on Aesthetics The filtration activity of mussels promotes water clarity, allowing more sunlight to reach the bottom of shallow systems, such as shorelines and bays, promoting benthic algal growth. These algae accumulate in the shallow areas and decay, resulting in a very unpleasant "muck ". This negatively impacts beneficial use of the water body for recreational purposes. Health hazards may include cuts from the shells piled at the beaches. Moreover, decaying mussel tissue material of mussels gives off noxious odor and contributes to increased organic content in the water, reducing the recreational and aesthetic values of water bodies. Economic Impacts Quagga and zebra mussels also pose a significant economic threat, in addition to their potentially devastating effects on the natural environment. U.S. Congressional researchers have estimated that the zebra mussel infestation in the Great Lakes area cost the power industry $3.1 billion between 1993 -1999, with an economic impact to industries, businesses and communities of more than $5 billion. Approximately $0.5 million is spent annually on zebra mussel control at individual water systems in the Great Lakes region. Direct economic costs are approximately $100 million annually in eastern North America; unquantified secondary and environmental costs could be substantially larger. Potential economic and environmental impacts in the Western U.S. could be greater than those in the East (California Science Advisory Panel, 2007). Dreissenid Mussel Monitoring and Control Although dreissenid mussels are not yet found in the waterbodies of the Watershed, the District needs to undertake proactive measures to monitor mussels in the watershed. The overall goal of the efforts will be to prepare a roadmap to protect the streams' and lakes' ecosystem, its water use, and recreational use from mussels' infestation. The major elements of monitoring and control may include: Page 44 BACKGROUND AND EFFECTS OF DREISSENID MUSSELS IN WATERBODIES - PRELIMINARY GUIDANCE FOR THE RILEY - PURGATORY -BLUFF CREEK WATERSHED Monitoring: a detailed description of the monitoring techniques to detect the extent of the infestation, and to understand seasonal population dynamics of mussels in streams and lakes of the District. Control measures: prepare a toolbox of proven mussel control strategies and technologies to deliver effective and operationally feasible mussel control and management options to contain, and eradicate mussels if they arrive in the Watershed. The implementation of the appropriate actions by the Districts will be to minimize the impacts to normal operations of the water use, resources, recreation, and economic activities. Specifically, this effort may include the following elements: 1. Methods for delineation of all species and stages of mussels in the water system; 2. Methods for control and eradication of adult mussels and decontamination of waters containing mussel larvae; and 3. Systematic monitoring program for measuring changes in conditions. Dreissenid Mussel Control Dreissenid mussel control strategies are typically separated into the following three categories: Preventative measures - Preventive controls are designed to prevent or delay the importation of mussels through regulation, including inspection of boats and public education. Principal features of this approach include public education, regulations, and monitoring. Proactive measures - The primary focus of proactive treatment is to prevent the attachment of veligers or the translocation of adult mussels to infrastructure (for example, water intake or pipes, equipment, water infrastructure) where functionality would be adversely impacted by the mussel colonization. Some of the control techniques include: Desiccation or drawdown of water body; Use of antifoulant paints or toxic materials of construction on infrastructure surfaces; Chemical treatment to kill the veligers. Reactive measures - Reactive control approaches are implemented when quagga mussels have become established in a water system. Reactive measures involve: Physical removal; Periodic shock treatment; Chemical control (such as, chlorine, permanganate, chlorine dioxide, ozone, chloramines, and non - oxidant- cationic polymers), Nonchemical approaches (thermal treatment and filtration); Pipeline pigging. Chemical control, such as chlorine treatment has a likelihood of some chlorinated disinfection by- products (DBP) formation depending on the system's water quality data, such as total organic carbon (TOC) levels averaging about 3 mg /L. The level of DBP formation potential depends on: TOC levels, water temperature, chlorine dose, pH, bromide level, and contact time. Based on these parameters in the water system, treatment details with consideration of compliance limits will need to be designed. The treatment options will also include the following - applicable permits, environmental regulations, chemical delivery and storage, chlorine feed lines, economics, and existing facility systems. Page 45 BACKGROUND AND EFFECTS OF DREISSENID MUSSELS IN WATERBODIES- PRELIMINARY GUIDANCE FOR THE RILEY- PURGATORY -BLUFF CREEK WATERSHED Preventative Measures The optimum control strategy is to prevent the infestation of these mussels into the waters of concern. However, if prevention is unattainable, delaying the eventual infestation will provide the District with substantial financial, usability, and recreational benefits. Preventive controls are designed to prevent or delay the importation of mussels through regulation, including inspection of boats, public education, and monitoring. Public Education Public education is the foundation of preventative measures. The first step of an effective educational program is to develop an attitude of concern. In order for any control strategy to be successful, the public, particularly potential users of lakes and other portions of the water conveyance system, must be aware of the problem. The second step is accepting the fact that user activities are a potential means of mussel transportation. The public must understand that they have a stake in prevention and that their activities are the most likely transport mechanism. And third, all users must adhere to recommendations put forth by resource managers. The public must be kept informed on what is required of them and that their response is of the utmost importance. Public education programs should include working with maintenance department on signage at boat landings and launches, Environmental Operations on alternate methods of notification to lake users (for example, DNR, volunteers, etc.) at boat launch check points, Park Board website, and news releases. Informing the public is the basis of this alternative, and effective strategies include newspaper articles, television coverage, presentations to user groups, mailings, installation of signs on boat ramps, handing out fact sheets, and handing out pocket cards with prevention strategies to boat owners. Studies have shown that the more effort that is put toward education, the more likely a recreational user will take steps to assist in the prevention process. Coordinating educational efforts with the relevant groups and agencies should provide synergistic benefits and opportunities to share costs. Regulation Public education alone is not sufficient to control the mussel infestation; it needs to be implemented along with regulatory measures. The regulations can effectively control the spread of such invasive species. It has been identified that recreational boating is the major transportation mechanism for mussels. Therefore, restriction of boats is found to be an efficient means of controlling mussels in a water body. Restrictions and regulations may include the use of the following: • No bait from outside the watershed • Mandatory boat inspections prior to off - loading boats • Ticket for traveling on highways with debris on boat trailers Monitoring The monitoring program should be focused on the most vulnerable components of the system, such as: Components that are connected to infested waters Page 46 BACKGROUND AND EFFECTS OF DREISSENID MUSSELS IN WATERBODIES - PRELIMINARY GUIDANCE FOR THE RILEY- PURGATORY -BLUFF CREEK WATERSHED • Components that allow recreational boating Boat inspections are an important element of a monitoring program and are typically supported by use of trained boat inspectors and the construction of boat cleaning stations. Conducting boat inspections will require coordination with the relevant authorities and state departments. Biological Control Technologies Biological controls, such as the introduction of known predators, have not produced adequate results to be considered a viable option at this time. A bacterial toxin from naturally occurring soil bacteria, Pseudomonas flourescens, has been identified that specifically targets zebra mussels (Malloy and Mayer 2007). However, this control measure is currently only in the development stage and undergoing regulatory permit testing with a possible commercialization and regulatory acceptance date of 2010. Preliminary Guidance To avoid the spread of mussels, the District needs to develop a multi- pronged approach including public education and outreach, monitoring, assessment, and consideration of various control, containment, and management strategies. It is important that the District select appropriate sites for monitoring and developing control strategies if mussels arrive. The District could use the following recommendations for developing a mussel monitoring and control plan: • As a first key step the District should conduct vulnerability analysis for mussel infestation for the District's lakes using physical and chemical properties (for example, calcium, pH, dissolved oxygen, turbidity, temperature, and alkalinity) of the waterbody. Common water quality parameters that correlate well with mussel survival and density are typically used to assess mussel infestation risk potential in water bodies (CH2M HILL 2009a; CH2M HILL 2009b; CH2M HILL 2009c). The environmental conditions offer an understanding of the existing water quality conditions and the colonization potential for mussels. • Develop and implement proactive measures to delay the arrival of mussels in the Districts' waterbodies. • Implement a monitoring program to assess the mussel presence/ absence. • Train personnel in monitoring of mussels and provide knowledge about the identification of these species and control methods • Collaborate with public, local and state agencies to ensure that appropriate measures are taken for protecting their infrastructure and systems from dreissenid mussel infestations. • Prepare and implement a boat inspection program • Develop a decontamination plan for equipment and boats that have had contact with the waters of an infested system. • Develop a toolbox of approved technologies for control and management of mussels.

CONSIDERATION OF RESIDENT REQUEST TO: • ENFORCE PARK HOURS AT SOUTH LOTUS LAKE PARK BOAT A CCESS • ADOPT AN AQUATIC INVASIVE SPECIES (AIS) POLICY • FURTHER SUPPORT THE VOLUNTEER AQUATIC INVASIVE SPECIES EDUCATION PROGRAM AT THE SOUTH LOTUS LAKE PARK BOAT ACCESS. Chairman Daniel thanked everyone in attendance and explained the role of the Park and Recreation Commission as an advisory body to the City Council. Todd Hoffman presented the staff report for this item. Lieutenant Jeff Enevold with the Carver County Sheriff's Office addressed details of the police contract with the City of Chanhassen and how law enforcement and park patrol works in the community. Tom Devine, 7640 asked for clarification of Lt. Jeff Enevold's statement that they do not have the resources to enforce park hours. Commissioner Ryan asked for clarification of what groups would be involved in developing an aquatic invasive species policy. Commissioner Tom Kelly asked if the training that the volunteers receive qualify them as a Level I or Level II inspector and if staff has any hard numbers on the long term maintenance and operation of a gate. Chair Daniel asked if other cities in close proximity to Chanhassen have adopted similar policies before opening up the meeting for public comments. Tom Devine, 7640 South Shore Drive commented on the DNR's involvement with citizen training and education, results of a survey showing that 90% of boats launched on Lotus Lake are not Chanhassen residents, concern that staff's recommendation did not include public input, highlights from their newsletter, training for Level I and Level II inspectors, and the need to study what other communities are doing. Steve Jenks, 7490 Chanhassen Road stated he would submit a written response to the questions laid out by the City Council, and clarified the role of the proposed automated gate. Joe Shneider, 1035 Holly Lane clarified the role of the DNR in addressing aquatic invasive species and asked that the City maximize the effectiveness of the proposed aquatic invasive species program at the Lotus Lake Park. Greg Dryke, 105 Choctaw Circle, manager of inspections, clarified that the DNlz is moving forward with their Level I and Level II inspection training. Mitch Krause, 2380 Timberwood Drive stated he was opposed to any gated access on any lakes in Chanhassen. John Colford, 7470 Chanhassen Road explained that a gate would not be unprecedented because there are currently automated gate systems being used in the Twin Cities and the Three Rivers Park District. Gary Simons, 7024 Tartan Curve, 2 Page 50 Park and Recreation Commission Summary - August 9, 2011 Eden Prairie, being a waterskier, explained he uses the Lotus Lake boat launch frequently and thinks it's a good idea to have inspectors but was concerned with the off site inspection sites. Dave Vonfruke, 131 Fox Hollow Drive, having experience with their family cabin on the White Fish chain of lakes, stated he would stress action over inaction. Bill Kirkvold, 201 Frontier Court, who took part in the DNR training, stated the City needs to take a leadership role instead of waiting for the DNR to take action. Pat Pavelko, 7203 Frontier Trail pointed out all the people who use Chanhassen lakes and beaches and the need to protect all the city lakes and asked that the City take a leadership role in stopping the invasion of zebra mussels. Brian Kirkvold, 44 Center Street, Excelsior quoted the DNR in saying zebra mussels are preventable. After commissioner comments and discussion on each of the three discussion points, the following motions were made. Daniel moved, Carron seconded that the Park and Recreation Commission recommend that the City comply with an action step in the DNR AIS Volunteer Manual and create a written agreement between the City and volunteer groups outlining expectations and procedures for adoption by the City Council. All voted in favor and the motion carried unanimously with a vote of 5 to 0. Ryan moved, Torn Kelly seconded that the Park and Recreation Commission recommend that the City Council moves forward with the very aggressive approach in terms of timing and developing a policy with the input of the citizens, city advisory committees and local, county, state and regional governing bodies to adopt an aquatic invasive species policy. All voted in favor and the motion carried unanimously with a vote of 5 to 0.
