Antelope Creek Fish Passage Improvement Project

Client: Resource Conservation District of Tehama County

Funder: California State Water Resources Control Board, Anadromous Fish Screen Program (U.S. Fish and Wildlife Service and Bureau of Reclamation), California Department of FIsh and Wildlife

Location: Tehama County, CA

Date: 2014 - Present

In 2014, Davids Engineering initiated the Antelope Creek Fish Passage Improvement Project to reconfigure and reconstruct the diversion facilities and fish screens at Edwards Dam. Fish screens were initially installed in the 1970s without bypass returns to Antelope Creek, requiring regular maintenance to manually remove debris and to rescue and return any trapped juvenile salmonids to Antelope Creek. Davids Engineering was contracted to resolve these issues by designing and managing the construction of improved fish screens, a bypass pipeline, and other necessary infrastructure at Edwards Dam.

Services that the Davids Engineering team has completed for this project include:
•Developing a design basis and design criteria
•Developing design drawings and cost estimates
•Documenting operation and maintenance requirements
•Monitoring diversion flows
•Surveying the project site
•Coordinating geotechnical analysis, environmental analysis, and environmental compliance efforts
•Construction management

This project will ultimately improve the downstream passage of protected Chinook salmon and Steelhead along Antelope Creek, reduce the risk of entrainment, and improve the accuracy, precision, and timing of irrigation diversions. The project will be particularly valuable during drought, as even modest reductions in diversion rate made possible by improved flow control are significant relative to low creek flows.
