This project will develop all designs required to achieve the restoration objectives including:

1) removing Rock Creek Road and Rock Creek Road Bridge, which constrict the channel of East Fork Mill Creek;

2) relocating the road and bridge onto an old roadbed; and

3) restoring floodplain connectivity and natural channel form and complexity upstream and downstream of the relocated road.

Achieving these objectives will improve spawning and rearing habitat for the Smith River coho salmon population.

Project Benefit    

Mill Creek contains the core coho salmon spawning and rearing habitat in the Smith River basin. Upon implementation the project will allow for enhanced floodplain connectivity, an immediate benefit to the Smith River coho salmon population. The restored reach will include greater channel complexity and in/off-channel habitat for spawning and summer/winter rearing capacity. Restoration of the broad floodplain at this location will also benefit Chinook salmon, Steelhead trout, and Pacific Lamprey.
