Landing Blitz 2023

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.

Every year, tens of thousands of Wisconsinites and visitors take to the water in early July to celebrate summer and the 4th of July, the state’s busiest boating holiday. Starting in 2023, our long running Landing Blitz has been fully incorporated into the Great Lakes Landing Blitz, joining all of the Great Lakes states and provinces in the effort to educate boaters that simple clean up steps and draining water from the boat and live wells can help to prevent the spread of aquatic invasive species. In Wisconsin from June 30-July 9th, 2023, many boaters will be greeted at landings and access points by 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 a brand new red, white and blue boat trailer sticker with a boat graphic showing people all the places where plants, tiny animals, and potentially contaminated water can hide! Share the word on social media by using #CleanBoatsCleanWaters. Questions? Contact Jeanne Scherer at or Erin McFarlane at

Together, we are all part of the solution for preventing the spread of aquatic invasive species.
