Aquatic invasive species inspections halt boat-borne invaders

Fish, Wildlife & Parks

So far this year, Montana Fish, Wildlife & Parks and its partners have inspected more than 84,000 watercraft, 46 of which were mussel-fouled and 300 were found with aquatic weeds.

More than 1,500 early detection samples have been processed this season, and no evidence of mussels has been detected in Montana waters.

Over the Labor Day weekend, it’s important to continue to clean, drain and dry your boat and gear when you recreate on the water to prevent the potential spread of aquatic invasive species, the agency reminded boaters.

Fall is the best time to detect new AIS populations when the water is low and at the end of the growing season. If you suspect an AIS population, take a photo, grab a specimen and contact FWP to report it 406-444-2449.

As a reminder, all boats must stop at all open watercraft inspection stations they encounter. Failure to do so could result in a fine of up to $500. Some inspection stations will begin shutting down after Labor Day, while others will operate into October.
