Inspectors are finding a rash of boats carrying invasive species into Montana, though the boating season’s busiest stretch is yet to come.
Montana Fish, Wildlife and Parks has intercepted 21 boats with invasive zebra or quagga mussels this season, compared to eight at this time last year.
“So we’re way above and beyond what we saw last season at this time,” said Tom Woolf, Aquatic Invasive Species Program Director.
Woolf says there’s also been an increase in overall boat traffic, with most infested ones coming from the Great Lakes and midwest regions.
