Watercraft Inspection Program

The annual aquatic invasive species (AIS) watercraft inspection program is underway for 2023. The program operates from late spring through the summer and into the middle of fall. There is no fee to use this service.

The schedule will be updated on a weekly basis.

The overland movement of watercraft and water-related equipment is the primary vector for transporting AIS to uninvaded water bodies in North America.
