Invasive Algae Found for the First Time in a Wisconsin Lake
An invasive algae spreading quickly through Michigan inland lakes has been found for the first time in Wisconsin — in Little Muskego Lake in Waukesha County.
The state Department of Natural Resources said that starry stonewort, a native to Europe and Asia, was discovered in the 506-acre lake in September.
It's the latest of more than 30 aquatic invasive species to strike Wisconsin. In some cases, such as zebra mussels, they wreak havoc on state waters. In others cases, these hitchhikers from other parts of the world have had a more limited impact.
The algae is known for growing in dense mats that crowd out native plants and wipe out habitat for young fish. Several weed harvesting machines now operate on the lake. One will be dedicated to starry stonewort on the eastern side of the lake
