Protect the lake from aquatic nuisance species. 
This is very important since Eurasian milfoil and other invasive species can ruin our lake.

Note: Boaters and Anglers, please remember that you can help prevent the spread of unwanted aquatic plant and animal species by following these guidelines:

  • Remove all mud and aquatic plants from all gear, boats, motors and trailers before departing from your fishing location.
  • Drain all water including bilge’s, live wells, and bait tanks before departing from your fishing location.
  • Do not transport fish from one body of water to another.
  • Do not release unused bait into a body of water.
  • Do not dispose of fish carcasses or by-products in any body of water.
