Aquatic Invasive Species Prevention


Aquatic Invasive Species (AIS) in general have few natural predators, high reproductive rates, displace native species and are living outside their native range. This makes the role of those living and visiting Brown County all the more important. Each of us can prevent the spread of invasive species by: inspecting for and removing vegetation from equipment, removing boat plugs, and properly disposing of minnow bucket water which can facilitate the transfer of invasive species to other surface waters.

The spread of AIS can be prevented through simple actions which all of us living in and visiting Brown County can easily adopt into our water safety routines. The result of these actions include: protecting water quality, fisheries, property values, and encouraging tourism. Alternatively, if we do not prioritize preventing the spread of AIS, the water resources that enable recreational activities such as boating, angling and swimming are exposed to the threat of AIS.  Remember to Clean, Drain, and Dry your equipment, replace bait water and be aware of lakes infested with invasive species around you! Each of us contributes to the health of lakes and streams in Brown County.

Waterbodies with AIS:

  • Minnesota River- Zebra Mussels (2017)

 What to look for?

         Zebra Mussels

 Curly Leaf Pondweed                                      Eurasian Watermilfoil

Check your watercraft trailer and equipment before and after boating, if you find any vegetation or dirt take a quick moment to remove all that you see to prevent the spread of AIS.
