About the Clark Fork River
Named for William Clark of the Corps of Discovery (Lewis and Clark), the Clark Fork begins its journey to the Pacific near Butte, Montana. Here the small headwater stream, Silver Bow Creek, twists and winds beside the Anaconda Settling Ponds until joining Warm Springs Creek at the Warm Springs Wildlife Management Area where it becomes the Clark Fork.

The Clark Fork forges west receiving the Big and Little Blackfoot Rivers, Rock Creek, the Bitterroot River, Petty Creek, Fish Creek, the Flathead River, Thompson River, and numerous small tributaries. In total, the Clark Fork drains more the 25,800 squares miles in Montana, Idaho, and Washington.
Miles of Trout Water
The Clark Fork supports trout from its headwaters to Paradise, Montana. That’s about 220 miles of trout water. In Paradise, the warmer Flathead River joins the Clark Fork, and warm-water species as well as brown trout, are the main catch. Look for trout where cold-water tributaries join the main stem of the river.
There are two sections of concern when drifting the Clark Fork. Alberton Gorge has Class lll – IV rapids and the river between St Regis and Paradise is boulder strewn.
