Flathead Lake Biological Station

The Confederated Salish and Kootenai Tribes are in the midst of their Mack Days fishing contest on Flathead Lake and their parallel gillnetting efforts aimed at reducing invasive lake trout numbers. Both are showing signs of working, but a this comes as one of the species’ main food supplies is going through some major changes.

There was something odd bubbling beneath the surface of Flathead Lake earlier this summer, but it wasn’t a lake monster. It was a submarine. Two, in fact. The subs' pilots were there to help cash-strapped researchers physically see the mostly unexplored depths of Flathead Lake for the unforgettable price of free.

Flathead Lake continues to defy national trends as a healthy blue body of water that’s free of invasive mussels. That’s according to the director of the University of Montana’s Flathead Lake Biological Station, who gave his annual state of the lake address Friday.
