Reclamation: Managing Water in the West. Environmental Assessment: Colusa Indian Community Council-Compton Diversion Fish Screen Project.

摘要

The Bureau of Reclamation (Reclamation) through the Anadromous Fish Screen Program (AFSP), which it co-manages with U.S. Fish and Wildlife Service (USFWS), proposes to provide federal funding to the Colusa Indian Community Council (CICC) to screen their existing 22 cubic feet per second (cfs) unscreened Compton Diversion (Proposed Action). CICCs diversion is located on the Sacramento River (River Mile (RM) 158.0), approximately 10 miles north of the town of Colusa, California. The Proposed Action is a cooperative effort between the AFSP, California Department of Fish and Wildlife (CDFW), Family Water Alliance (FWA), and CICC. The fish screen meets design requirements of the National Marine Fisheries Service (NMFS) and CDFW (CDFW 2000, NMFS 1997). The Central Valley Project Improvement Act (CVPIA), Section 3406(b)(21), authorizes the Department of the Interior to develop and implement measures to avoid losses of juvenile anadromous fish resulting from unscreened diversions on the Sacramento and San Joaquin Rivers and their tributaries. These measures include construction, rehabilitation, and replacement of fish screens and relocation of diversions to less fishery sensitive areas. The Proposed Action would help to prevent listed and other migratory or resident fish species in the Sacramento River from becoming entrained or otherwise impacted by the continued use of the pumps.
