About the Great Lakes AIS Landing Blitz

Boaters and other recreators learn about the risks of spreading aquatic invasive species (AIS) at public and private boating access sites across the Great Lakes region every summer. The Great Lakes AIS “Landing Blitz” events take place over a two-week period, emphasizing the need to Clean, Drain, Dry boats whenever they come out of the water, and Dispose of any unwanted bait in the trash.

Local volunteers partner with state and provincial agencies to deliver consistent messaging about preventing the introduction and spread of AIS from the movement of watercraft and equipment between water bodies. Information on these events, including educational materials, locations and volunteer opportunities are posted on this page as they become available.

The Great Lakes AIS Landing Blitz is a multi-agency partnership effort. The 2025 event will take place from June 30 through July 13, 2025. Fact sheets on the 2024 grant recipients and 2024 basin-wide events coming soon!
