摘要

Battle Creek is located in northern California and is a cold water tributary to the Sacramento River. Development of Battle Creek for hydroelectric power generation began in the early 1900s and resulted in the eventual construction of five diversion dams on the North Fork and three diversion dams on the South Fork, along with a complex canal system, to support five high-head, low-volume powerplants. The Battle Creek Hydroelectric Project has been owned and operated by the Pacific Gas and Electric Company (PG&E) since 1919, and is currently licensed by FERC through 2026. Declining salmonid populations in the Sacramento River system, aggravated by ineffective fish ladders, unscreened diversions, and inadequate streamflows, resulted in a multi-agency agreement with PG&E in 1999 to pursue a plan for Battle Creek that would restore and enhance approximately 48 miles of anadromous fish habitat while maintaining the economic viability of the Hydroelectric Project. The Battle Creek Restoration Project includes the installation offish screens and ladders at three diversion dams, the removal of five diversion dams, the construction of two tailrace connectors and a penstock bypass to prevent canal flows from entering the South Fork; and an increase in streamflows by reducing diversions. Contracts for the project work on the North Fork were awarded in 2009 following FERC approval of PG&E's license amendment application, with the remaining work to be contracted as additional approvals and funding become available. This paper will describe the NEPA/CEQA compliance process, final design features, and construction status for the Restoration Project.
