The project area is located on the lower Yuba River just downstream of Englebright Dam, Yuba County, California. The spawning gravel placement and redd monitoring area is confined to the river channel located between Englebright Dam and the junction with Deer Creek. This area is called the Englebright Dam Reach (EDR) and it is located in the steep canyon off Highway 20, about 23 miles east of Marysville, California.

The U.S. Army Corps of Engineers (Corps) is proposing to provide oversight and monitoring of spawning gravel placement and to survey, monitor, record and map salmon/steelhead nests (Redds) in the EDR resulting from the placement of the spawning gravels. The purpose is to guide placement of the gravels to increase the likelihood of use; evaluate and record the successful use of the gravels by anadromous fish; and monitor the gravel as it moves downstream during high flow periods.

The gravel placement program continues placement of suitable-sized spawning gravel for rehabilitating associated geomorphic processes and aquatic habitat in the Englebright Dam reach of the Lower Yuba River. It is hoped that implementation of a long-term augmentation program will serve to improve the overall ecological functionality of the channel by providing gravel and cobble suitable for anadromous salmonid adult spawning, embryo incubation, and survival to emergence to key areas on the lower Yuba River that have been designated as critical habitat for the Central Valley spring-run Chinook salmon and the Central Valley steelhead. In addition, the gravel oversight and monitoring program will observe and record the movement and use of gravel to help guide future placement efforts.
