I am befuddled by a letter addressed to Eric Evenson and copied to Adam at the city regarding a letter of support that was reconsidered and withdrawn from a previous stance of the LMCD. In my opinion, it missed the mark and goes against the "Lake Minnetonka Vegetation and Aquatic Invasive Species Plan," approved in June 2020.... Notice below that we clearly decided to promote LIDS, i.e., the group trying to form a LID in Stubbs Bay, with help from the LMA.... Please consider this as we go forward with the discussion at the Public Forum next Monday night.... In my work with Crystal Bay formation of trying to get a LID, even though established legislation says "a majority" of petitioners (51 %), I was never comfortable with that percentage of involvement.... Not enough of the masses to make it fair, my thought was to get to 75% or so to bring it up to the council.... Never got there, so I never went forward for Crystal Bay.... Sounds like this group is in the middle to high 70's.... It is refreshing to see the overwhelming support of the residents on that bay to clean it up.... From the 2020 report: LMCD synopsis, form LIDS: Page 30 Recommendation: Results from 2019 aquatic plant focused meander survey efforts conducted on Lake Minnetonka found EWM and native plant growth is mostly light to moderate over much of the nearshore areas that are not involved with bay -wide management areas. In most cases, EWM was intermixed with native species. It is important to note aquatic vegetation density may vary significantly from year to year based on weather and other factors. With the advent of herbicides like ProcellaCOR that are selective for EWM, the impact to non -target species can be minimized by using herbicides as the primary control technique rather than mechanical harvesting, which is a non -selective control technique, thereby meeting the LMCD goal of increasing native aquatic plants. Furthermore, wide, expansive areas, like the EWM beds in Crystal Bay, are most cost-effectively managed with herbicides, thereby meeting the LMCD goal of leveraging available funds. It is recommended that the LMCD work with the LMA, Lake Improvement Districts (e.g., North Arm Bay and Libbs Lake Association), and the MNDNR to identify the areas of the lake in which herbicide treatments are most likely to be effective and the type of herbicide that is best suited for the targeted area. The areas subject to control via herbicides are subject to change annually due to inter -annual changes in aquatic plant growth. Blue Water Science has prepared Table 1, which summarizes the corresponding characteristics for commonly used herbicides. The LMCD will also work with the MNDNR and the LMA, and other stakeholders to evaluate which herbicide to use and when bay -wide techniques should be 275
