ECHO LAKE ASSOC, LTD: Echo Lake 2-yr AIS Management Planning and Education Project

Purpose

The Echo Lake Association is sponsoring a two-year project to conduct AIS education and monitoring activities and update their APM plan. Deliverables include AIS monitoring & watercraft inspection data in SWIMS, examples of AIS education & outreach, shoreline & woody habitat monitoring results & report, aquatic plant survey results, and an updated APM plan. Specific project activities include: 1) Watercraft inspection; 2) EWM monitoring and treatment planning; 3) Volunteer AIS monitoring; 4) AIS outreach & education; 5) Shoreline and woody habitat surveys; 6) Spring and summer whole lake point intercept plant surveys. Special Conditions: 1) Sponsor shall contact DNR immediately if a new AIS is found; 2) Watercraft inspection and AIS monitoring personnel shall be trained and follow DNR approved protocols; 3) Watercraft inspection and AIS monitoring data shall be entered in SWIMS; 4) Education materials shall be consistent with the Department\2019s statewide education strategy for preventing and controlling AIS; 5) WDNR\2019s Aquatic Plant Management in Wisconsin guidance shall be followed for point-intercept survey monitoring and aquatic plant management plan development. The NOR Native Plant Protection Strategy shall be integrated into the APM plan. This scope is intended to summarize the detailed project scope provided in the application and does not supersede those application tasks/deliverables. Data, records, reports, and education materials, including GIS-based maps and digital images, must be submitted to the Department in a format specified by the regional lake coordinator.

Reports and Documents
Following three EWM monitoring and manual rake removal surveys in 2018 that documented a significant uptick in EWM in the northeast bay, the ELA, under the direction of Lake Education and Planning Services, Inc. (LEAPS), decided to treat 3.84 acres with granular 2, 4-D (Shredder Amine 4) with a target concentration of 4ppm on June 2, 2019. Posttreatment, we were asked to complete two lakewide EWM monitoring and manual rake removal surveys over the summer and a third survey in the fall if we found a significant number of plants. This report is the summary analysis of our surveys on the lake in 2019. These data will also be used to determine if and where EWM control might be considered in 2020.
This report is the summary analysis of our three field surveys to locate and remove EWM on the lake in 2017. These data will also be used to determine where EWM control might be considered in 2018.

Following 13 years of active management that included herbicide treatments covering a total of 62.43 acres, EWM was reduced from 106 points with a mean rake fullness of 1.28 in August 2007, to one point in July 2012, to no points in July 2017. Continuing to aggressively manage EWM to limit its spread while simultaneously working to minimize its impact on Echo Lake’s native plants and keeping economic costs low; and proactively working to limit nutrient inputs around the lake which can fuel both algal as well as milfoil growth are management priorities for the ELA to consider as they update their management plan.
