Contractor Services Group Inc. of West Sacramento has been awarded a contract worth about US$3.6 million to construct a new fish barrier and weir as part of the Battle Creek Salmon and Steelhead Restoration Project.
The Battle Creek Salmon and Steelhead Restoration Project — a collaborative effort between the U.S. Bureau of reclamation, the U.S. Fish and Wildlife Service and the Pacific Gas and Electric Company (NYSE: PCG) — is intended to help restore fish habitat and in turn, increase the number of Chinook, steelhead and other threatened species living in California’s Baldwin Creek.
Reclamation awarded the bid to Contractor Services Group after the Federal Energy Regulatory Commission (FERC) amended PG&E’s hydroelectric license for its operation at Baldwin Creek, thus allowing for construction of the fish barrier and weir.
The new barrier and weir will allow a constant five cubic-feet-per-second of minimum flow in Baldwin Creek, which is located downstream of the Darrah Springs State Trout Hatchery.
Reclamation said the flow is necessary for the salmon and steelhead living in the creek, while the barrier weir is meant to protect the hatchery from pathogens that could be transmitted via infected anadromous fish.
“With a record number of Spring Chinook Salmon returning to Battle Creek this year, further indicating the ongoing success of the Battle Creek Salmon and Steelhead Restoration Project, this construction project is necessary to provide for additional salmon habitat and to protect the valuable recreational trout fishery,” Reclamation Commissioner Michael L. Connor said.
Remaining portions of the fish habitat restoration project include the construction of a fish screen and ladder on Inskip Diversion Dam and a tailrace connector from South Powerhouse to Inskip Canal, as well as the removal of the Lower Ripley Creek Feeder, Soap Creek Feeder, and South and Coleman Diversion Dams.
