This summer, the Minnesota Department of Natural Resources has reported new infestations of aquatic invasive species – zebra mussels and starry stonewort – at a dozen lakes across the state. The discoveries underscore the inherent challenge of protecting Minnesota waterways in a state with more than 11,000 lakes, thousands of natural and manmade connections, and countless ways to access the water from public and private lands.

Keeping invaders out of Minnesota waters

In 2024, Minnesota deployed more than 800 watercraft inspectors to public boat launches around the state to help staunch the spread of zebra mussels, spiny waterflea, and other aquatic invaders. The goal? Preserve Minnesota’s famed “good life” and protect fishing, tourism, and cultural mainstays such as wild ricing and “up north at the cabin.”

One reason for optimism is that we are seeing fewer new infestations and better compliance with state laws for watercraft cleaning and inspections.

Unfortunately, however, the DNR still reported 41 new AIS infestations in Minnesota lakes and rivers last year.

During Starry Trek, scheduled this year for Aug. 20, volunteers gather at training sites to learn how to identify starry stonewort and then head out to local water accesses to search for signs of the invasive species.
