Invasive mussel spreading in Montana over for now, could pick up again in spring

By  | 

MONTANA - At the beginning of December, the Canyon Ferry and Tiber Reservoirs in Montana were closed to boating to prevent the spread of invasive mussels. Those restrictions have now been lifted.

The Mussel Response Team said that when water temperatures drop below 48 degrees, they don't reproduce.

Several samples tested positive for mussel larvae at the Tiber Reservoir, and it is suspected that at least three other sites could have them as well.

The team will weigh its options before deciding on a direction to take when the snow melts this spring.
