This funding represents a 50% match, up to the maximum amount of $5,000 per lake. A match is required by the Lake Associations and any outside grant amounts received would not be included as part of the Lake Association match amounts. ISSUE BEFORE COUNCIL: Does Council approve the grant request of $5,000 from the Lake Elmo Lake Association? PROPOSAL: The Lake Elmo Lake Association has submitted an application for matching grant funding to treat Eurasian Milfoil this summer. A copy of their application is included in your packet. FISCAL IMPACT: $5,000 from the $15,000 in the 2023 budget OPTIONS: 1) Approve $5,000 for Lake Elmo Lake Association Eurasian Milfoil Treatment 2) Approve a different amount for Lake Elmo Lake Association Eurasian Milfoil Treatment 3) Do not approve any funding for Lake Elmo Lake Association Eurasian Milfoil Treatment RECOMMENDATION: If removed from the consent agenda: “Motion to approve the Lake Elmo Lake Association lake improvement grant request of $5,000 ATTACHMENTS: • Lake Elmo Lake Association Grant Request Form EWM Delineation Lake Elmo (Washington Co, MN) – June 2023 © 2023 – Freshwater Scientific Services, LLC Page 1 of 5 ... 2023 Eurasian Watermilfoil Delineation Lake Elmo (# 82-0106) Washington County, MN Surveyed June 7, 2023 Surveyed by: Krista Espelien – Environs, LLC Analysis, and Reporting by: James A.

Purpose of Survey This spring survey was conducted to locate and delineate areas of Eurasian watermilfoil (EWM) in Lake Elmo (#82-0106). This information will help to guide future management decisions and meet DNR permit requirements. EWM Delineation Survey We surveyed Lake Elmo on June 7, 2023. During this survey, we navigated a meandering path over the vegetated portion of the lake, with the exclusion of areas dominated by lily pads, bulrush, or cattails. While navigating this search path, we used a combination of surface observations, sonar readings, and rake tosses to locate and delineate areas of EWM growth. When we encountered EWM plants, we marked the location, recorded the water depth, and rated the density of the growth using density scores as described in the table below. For rake samples, we dragged a sampling rake over approximately 10 square feet of lake bottom and recorded the EWM density based upon the number of plants (stem count) retrieved on the rake. The recorded water depths and density scores were linked to the appropriate GPS locations and then mapped using desktop GIS software. Survey Method Score Visual Rake 1 Light / Solitary plants 1-2 stems 2 Moderate / Scattered dense patches 3 to 9 stems 3 Dense / Uniform dense growth 10+ stems EWM Delineation Lake Elmo (Washington Co, MN) – June 2023 © 2023 – Freshwater Scientific Services, LLC Page 3 of 5 ...
