RED CEDAR LAKES ASSOCIATION: Curly Leaf & Purple Loosestrife Control & Monitoring 2013 - 2015

Purpose

Red Cedar Lakes Association is sponsoring a 3-yr project to implement approved activities from the Red Cedar Lakes Aquatic Plant Management Plan. Project deliverables include GIS data & maps of areas monitored, aquatic plant & turion monitoring results, examples of AIS education & outreach, AIS monitoring & watercraft inspection data in SWIMS, water quality data in SWIMS, management/treatment summaries. Specific project activities include: 1) Curly-leaf pondweed chemical & manual control; 2) Purple Loosestrife control; 3) Pre-post treatment aquatic plant monitoring; 4) Turion monitoring; 5) Hire AIS Coordinator; 6) Watercraft inspections; 7) AIS monitoring & education; 8) Dissolved oxygen and temperature profile monitoring; 9) Wild Rice mapping & education. Special Conditions: 1) WDNR\2019s Aquatic Plant Management in Wisconsin guidance shall be followed for aquatic plant monitoring; 2) Sponsor shall contact DNR immediately if a new AIS is found; 3) AIS monitoring and watercraft inspection personnel shall be trained and follow DNR approved protocols. This scope summarizes the project detail provided in the application and does not negate tasks/deliverables described therein. Data, records, and reports, including GIS-based maps, and digital images, must be submitted to the Department in a format specified by the regional Lakes Biologist.

Reports and Documents
Herbicide treatment of CLP on Hemlock and Red Cedar Lakes. The acreage treated on Red Cedar Lake increased due to a pre-survey indicating an increase in the amount of CLP on the lake. Water sampling, secchi data, dissolved oxygen rates monitored by volunteers for Red Cedar Lake, Balsam Lake, and Hemlock Lake. Clean Boats Clean Waters monitored landings and then treatments of hand-cutting, bio control, and spraying were used to treat problem areas. Public education was also done.
Two plots, one in Red Cedar Lake and one in Hemlock Lake, were treated with endothall on May 8, 2015 to control curly leaf pondweed (Potamogeton crispus; henceforth referred to as “CLP”). We conducted point-intercept vegetation surveys in both treatment plots prior to treatment (April 23, 2015; “pretreatment”) and again about 1 month after treatment (June 1, 2015; “posttreatment”). These surveys were designed to assess whether the treatments effectively controlled CLP in the treated plots and to document any changes in the frequency and abundance of native aquatic plants. In addition, we collected sediment samples from both plots on Oct 22, 2015 to assess the abundance and distribution of curly leaf pondweed turions (reproductive buds).
The Red Cedar Lake Association asked Freshwater Scientific Services to evaluate curly leaf pondweed growth and sediment turion abundance in two additional areas of Red Cedar Lake (Plot 1 in north-central bay, Plot 2 near Pigeon Creek inflow site) to help determine whether these areas should be considered for management in 2016 and beyond.
