Clark Canyon Reservoir Professional Review and Guide

"Clark Canyon Reservoir is a large, 6,600-acre reservoir that was created by construction of Clark Canyon Dam on the headwaters of the Beaverhead River. Red Rock River to the southeast and Horse Prairie Creek to the northwest combine to form the waters of the reservoir. Clark Canyon Reservoir is primarily a rainbow trout fishery, although there are sizeable brown trout and burbot or ling populations, and a fair amount of suckers and other nongame species.

In 1989, FWP stopped stocking the Arlee rainbow and concentrated instead on two wild strains, the DeSmet and Eagle Lake rainbow. Though slower growing, these strains show better staying power and a stronger proclivity to reproduce in the wild. Springtime is the most popular time of year for fishing, with spring activity culminating at the Dillon Rotary Club’s Fish Derby held on Father’s Day. This event attracts out-of-state as well as local anglers. The competition and the fishing are fast and furious. As soon as the ice comes off the reservoir in March or April, you’ll find anglers out on the water. Both brown and rainbow trout are active at this time."
