What are Aquatic Invasive Species?  

 Aquatic Invasive Species are non-native plants, animals, and other organisms, living primarily in water, that have been introduced beyond their native range and eventually out-compete native species. Left unchecked, these invaders can greatly affect lake and stream ecosystems as well as how we use and enjoy them. Thankfully, because of current outreach and prevention programs, only a small percentage of Minnesota lakes are infested with AIS; however, these efforts must be ongoing in order to slow future AIS populations from establishing in other waterbodies. 

Wadena County's Current AIS Status: 

In 2009, the MN DNR classified Lower Twin Lake as infested with Faucet Snails. Almost 10 years later, in 2018, the presence of Faucet Snails was discovered in nearby Blueberry Lake, adding it to the list of infested waters in Minnesota.



What We're Doing: 

  • Watercraft Inspection Program

Each Spring, Wadena County hires roughly 5 watercraft inspectors who obtain annual training through the Minnesota DNR.  These inspectors are then distributed to either Stocking, Blueberry, Spirit, or Twin lake to conduct inspections at each access.

What Can You Do? 

  • Take the pledge to prevent aquatic invasive species!

In 2022, the Minnesota DNR began a new online pledge to help slow the spread of aquatic invasive species. The pledge affirms that any participate 18 years or older will follow the state’s “Clean, Drain, Dry” laws and encourage others to do the same.
