The Silver Lake Association (SLA) and the Wisconsin Department of Natural Resources (WDNR) authorized a full lake plant survey in 2012 as a prerequisite to developing an Aquatic Plant Management Plan (APMP) in 2013. This survey found no evidence of Curly-leaf pondweed (Potamogeton crispus) (CLP), Eurasian water-milfoil (Myriophyllum spicatum) (EWM), or any other aquatic invasive plant species (AIS) in the lake with the exception of Reed canary grass (Phalaris arundinacea) (RCG) which was common on the lake’s margins. In an effort to determine if the lake remained free of harmful exotic species, the SLA applied for and received an AIS education grant to complete two littoral zone surveys during the summers of 2018-2020. This report is the summary of our June 19 and August 24, 2020 surveys.

An aquatic invasive species (AIS) survey was conducted on Silver Lake, Barron County WI in June and August, 2019 to evaluate the presence of aquatic invasive species present in Silver Lake. The survey included a meander survey in June and August, as well has installing sampling plates for zebra mussel (Dreissena polymorpha) monitoring. Silver Lake is a 331 acre seepage lake with a maximum depth of 91 feet. The lake is classified with a trophic status of mesotrophic.
