Rock Creek, one of main tributaries to the North Umpqua River, is a major contributor to OC coho, spring and fall Chinook, summer and winter steelhead, cutthroat trout and Pacific lamprey production. A new fish ladder, located at the dam near the mouth of Rock Creek, has greatly improved fish passage, but poor upstream habiat still limits fish production. In-place instream restoration projects are already working to increase fish survival. Restoration work planned for 2014 implementation will occur immediately downstream from already restored habitat and will include 1,400 boulders, 20 trees and 51 logs placed at 19 sites.

The long-term outcome of the Rock Creek Restoration Project is the restoration of historic runs of wild anadromous fish to the watershed. This will be accomplished through watershed-scale instream and side channel habitat restoration. This phase of instream restoration work includes the placement of 51 logs, 20 trees and 1,400 boulders throughout 19 sites in Rock Creek and will create specific habitats: slow flowing meanders, juvenile fish refuge areas, spawning gravels for spring Chinook, summer steelhead and coho, and deep pools for upstream migrating fish.
