HELENA – Montana’s first mussel-fouled watercraft of the year was intercepted at the Anaconda watercraft inspection station on March 10.  

The pontoon boat was recently purchased used in North Dakota and was travelling along Interstate 90 west toward Ephrata, Wash. Mussels were found along the hull throughout the lifting strakes as well as the transom and gimbal areas. Inspectors performed a full decontamination on site, and the boat was locked to the trailer. Previous launch information was unknown, but the new owner believed it had not been in the water since last summer. 

All watercraft (motorized and non-motorized) coming into Montana from out of state must be inspected. Watercraft must be drained of all water before transporting. 

Watercraft inspection stations are Montana’s first line of defense to prevent the movement of aquatic invasive species (AIS) which can have devastating impacts on Montana waterways. Boaters must stop at all watercraft inspections stations they encounter.
