Zebra Mussels found in Lake Menomin

The Wisconsin Department of Natural Resources (DNR) has informed the City of Menomonie that Zebra Mussels have been found in Lake Menomin.


What are Zebra Mussels:  

Zebra mussels are a small mollusk that are an invasive species in Wisconsin.  

They often impact plankton and algae populations in bodies of water which can harm fish populations. They avoid eating blue-green algae which can increase toxic algal blooms.  

What’s being done to prevent further spread: 

The City of Menomonie and Wisconsin DNR are working together to  

prevent further spread.  

  • Wisconsin DNR will monitor public boat ramps. 

  • The City of Menomonie installed a boat wash station at the Lakeside Park boat launch. 

  • The City of Menomonie was awarded a Wisconsin DNR grant to install a second boat wash at Point Comfort Park by 2026.  

What can you do to prevent the spread of invasive species:  

  • INSPECT your boat, trailer, and equipment. 

  • REMOVE any attached aquatic plants or animals (before launching, after loading and before transporting on a public highway). 

  • DRAIN all water from boats, motors and all equipment. 

  • NEVER MOVE live fish away from a waterbody. 

  • DISPOSE of unwanted bait in the trash. 

  • BUY minnows from a Wisconsin bait dealer. Use leftover minnows only under certain conditions.
