by private landowners and mechanical weed pulling. It also includes lakewlde assessment of EWM growth via aerial surveys and vegetation assessments during treatments. This plan identifies Carman Bay as a suitable candidate for large scale herbicide treatments, ranking it at 41h of seven bays so identified. In the current Lake Minnetonka AIS management strategy, responsibility for the baywlde herbicide treatments falls to the local property owners; the activities of the proposed LID would take over this part of the management plan. If any new AES become established in Carman Bay, the DNR encourages the LID to coordinate with the DNR, the LMA, and the LMCD to devise, adopt and carry out any management actions needed for these new AIS. Because zebra mussels have already been found in the bay, the LID may want to consider adding monitoring for zebra mussel distribution in the bay, and if necessary management of mussels, to its scope of activities. The bay is easily accessible from a large number of points. There is a public beach and several public access points at the ends of streets. Although there are no public boat launches on the bay, there are two licensed multiple dock areas—Pheasant Lawn HOA and Waiters Port Association'. The bay also has a very open connection to the rest of Upper Lake Minnetonka. All of these areas provide opportunities for new AIS to be introduced, and for those already present to be transferred elsewhere. The petition does not discuss monitoring, cleaning stations, or educational efforts at any of these locations, but such efforts are a key component in managing and limiting the spread of AIS. The DNR strongly encourages working with the Pheasant Lawn HOA and the Walters Port Association to implement a campaign to promote AIS prevention and management at these locations. The local AIS specialist, Keegan Lund (Keegan.lund@state.mn.us, 651-259-5828) and the local contact for the DNR's Watercraft Inspection Program, Adam Doll (Adam.Doll @state.mn.us, 651-259-5835), can provide guidance on these efforts. In addition, the DNR issues grants to help with many of these activities, and Hennepin County may also. See http://www.dnr.state.mn.us/grants/aquatic_ invasive/index.html, or contact AIS Grants Coordinator Wendy Crowell (wendy.crowell@state.mn.us, 651-259-5085) or DNR Ecosystem Management and Protection Section Manager Ann Pierce (a nn. pierce Ostate.mn.u 6651-259-5119) for possible funding opportunities. Recommendations/Conclusions Proposed LID Boundaries The boundaries of the proposed LID include only properties adjacent to Carman Bay. It does not include all of Lake Minnetonka. MR part 6115.0920 subpart 5 requires that the boundaries include all lands and waters within the direct drainage basin of the lake (shown on the attached map). However, this rule also allows the County Board or City Council to create a boundary less than the entire drainage basin with written Commissioner approval if the boundary selected includes a sufficient amount of the lake's watershed to develop and implement feasible solutions to the problems the LID intends to address. Restriction of the district's boundary to the riparian properties of the bay is sufficient to address the AIS mitigation for which the LID is being proposed, and this practice would be consistent with the history of AIS management as currently conducted in Lake Minnetonka and as described in the LVMP. Therefore, in accordance with these rules, the DNR approves the proposed boundaries identified in the resolution. 4 Lake Minnetonka Conservation District {LMCD) Comprehensive Eurasian Watermilfoil and Curly -leaf Pondweed Management Plan, 2013
