Began Lake Assessment Program
2005 Curly leaf Pondweed very thick. Waterville Lakes Association’s goal is improving water quality and recreational enjoyment of Lakes Tetonka and Sakatah. Working towards this goal we are sponsoring a weed control program for reduction of the exotic CurlyleafPondweed. Spraying with a DNR It EP A approved aquatic herbicide is done in early spring by a licensed applicator. Our experience has shown that in the treated areas there is good control of the Curly Leaf Pondweed, allowing the beneficial native weeds (Clasping leaf, Coontail. etc) to grow well. Fish and wildlife are not banned with this process. We are approaching this as a maintenance program as we know we will never rid our lake of Curly leaf Pondweed, but will reduce tbe expansion of it.
Lakeshore members pay for their shoreline Weed spraying and donate to the Lake Weed spraying. Associate members help to pay for the spraying of the lake weeds. Higher membership in The Lake Association gives more of a voice in Legislation and Policies to protect our lakes. Business sponsors help to pay for spraying of the lake weeds and are working with the Waterville Lakes Association to promote tourism and water quality.
