Landing Blitz 2022

Every fourth-of-July holiday, AIS Partnership members and Clean Boats Clean Waters volunteers reach out to boaters across Wisconsin with a simple but powerful message: You have the power to protect lakes and rivers from aquatic invasive species.

The Landing Blitz is a statewide effort to remind boaters and other water lovers to take action to stop the spread of aquatic invasive species, which pose great risks to the health of our lakes and fisheries. Volunteers are stationed at boat landings around the state to give demonstrations of the prevention steps that boaters must take before they leave the water:

  • Inspect your boat, trailer and equipment
  • Remove all attached plants or animals
  • Drain all water from boats, motors, livewells and other equipment
  • Never move live fish away from a waterbody
  • Dispose of unwanted bait in the trash
  • Buy minnows from a Wisconsin bait dealer, and use leftover minnows only if you will be using them on that same waterbody or if no lake or river water or other fish were added to the container.

Following these steps also helps boaters comply with Wisconsin state law, which prohibits the transport of aquatic invasive species.

Thousands of Wisconsinites and visitors take to the water Fourth-of-July weekend, the state’s busiest boating holiday. During the twelfth Annual Landing Blitz, July 1st– July 5th, many boaters will be greeted at landings and access points by Wisconsin Department of Natural Resources staff, volunteers and regional Aquatic Invasive Species (AIS) partners sharing a simple but powerful message: YOU can protect lakes and rivers from aquatic invasive species. Clean Boats Clean Waters boat inspectors will give out Stop Aquatic Hitchhikers boat towels by reminding people to remove all plants, tiny animals, and mud as well as to drain all water from your watercraft. Wisconsin is also a partner for the fourth annual Great Lakes Region Landing Blitz on July 1st to July 10th! Share the word on social media by using #CleanBoatsCleanWaters. Questions?
