In a gradual journey up the lower Clark Fork River, trout are once again ascending the tallest fish ladder in Montana.
Climbing 48 vertical feet, the upstream fish passage facility, or fish ladder, is part of the Thompson Falls Hydroelectric Project in northwest Montana. The full-height facility, owned by NorthWestern Energy and operated cooperatively with Montana Fish, Wildlife & Parks, runs from late March to the end of October. In the first month since the ladder reopened this spring, more than 50 large rainbow trout, two brown trout, and five westslope cutthroat trout have already achieved documented ascents.
