Larvae from aquatic invasive mussels have been detected in Montana for the first time.
Water samples from Tiber Reservoir east of Shelby tested positive for the larvae of aquatic invasive mussels, with similar tests from Canyon Ferry Reservoir near Helena showing “suspect” or inconclusive results, according to officials at Montana Fish, Wildlife and Parks.
FWP, along with other state and federal agencies and the Montana Invasive Species Advisory Council (MISAC), are now working to determine whether adult mussels are present in Tiber Reservoir and to get further test results on Canyon Ferry.
