Project Description
Crow Creek is a fourth order tributary to Prospect Creek in the Lower Clark Fork River. Historically, Crow Creek was dominated by dense stands of large cedar. The riparian corridor within the project area had been extensively altered resulting in channel instability, loss of pool habitat, and channel-floodplain disconnection. RDG worked with project partners to complete a channel and floodplain restoration design aimed to improve migratory habitat conditions for bull trout. The project restored approximately 0.2 miles of channel and floodplain. A variety of restoration techniques including large wood structures, bioengineered soil lifts, and constructed riffles were used.

Clearing of riparian vegetation and mature cedars simplified aquatic habitat conditions and destablized the channel (photo prior to construction in 2006).
