Aquatic Invasives Control
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.
