Montana Watersheds

Running 360 miles from the headwaters near Butte and Anaconda through western Montana across the Idaho border to Lake Pend Oreille and on into the Columbia River, the Clark Fork River drains Montana’s western front, and carries the largest volume of water of any of the state’s rivers when it crosses the border.

The Clark Fork links the largest contiguous complex of federal Superfund sites in the U.S. Ecosystems and communities in the area have been heavily impacted by historic mining and smelting wastes. Hundreds of millions of dollars are being spent to restore the basin back to a fully functioning, healthy watershed. The largest Superfund site in the U.S. also serves as a showcase for environmental understanding, and how a damaged ecosystem can be restored.
