Description

Grantee and partners upgraded 1.69 miles of forest road and decommissioning (closure) of 2.84 miles of abandoned, decaying, streamside, mid-slope, and inner gorge roads in the Indian Creek watershed. The project has prevented the delivery of approximately 5,100 yd3 of sediment from road-related sediment delivery features to Coulborn and Sebbas Creeks, thereby providing increased protection and improvement of salmonid habitat.

See the final report for details.

Project Benefit

Improve instream habitat conditions by reducing sediment delivery, improving water quality for all life stages of salmonids in Sebbas and Coulborn Creeks.
