000925 Redland Fish Screen FONSI W ACO-GJ-FONSI-04-01 Page 2 Alternatives: The EA evaluated No Action and Proposed Action Alternatives. Under the No Action Alternative, the Recovery Program would not construct or provide funding for operation and maintenance of a fish screen in the Redlands Power Canal. Adult and subadult Colorado pikeminnow and razorback sucker could continue to become entrained in the Rl?dlands Power Canal and be lost by continued R WPC operations. Under the proposed action, the Recovery Program will construct a fish screen in the Redlands Power Canal to prevent canal entrainment of adult and sub adult Colorado pikeminnow and razorback sucker. Reclamation will design and construct the fish screen and the Recovery Program will provide fish screen operation and maintenance funding for the fish screen and Redlands fish ladder through the execution of an O&M agreement between Reclamation., the Service and R WPC. R WPC will assume ownership of the fish screen and fish ladder. The proposed action includes a "V-type" fish screen configuration with each leg of the screen being 160 feet long, a bypass channel, and a fish return pipeline. The screen is designed for a total diversion of 890 cfs with 40 cfs for the fish return pipeline, for a total screen flow of 850 cfs (RWPC Water Rights). The fish screen will be completed under Reclamation construction contracts. R WPC will continue to participate in the design and construction process to ensure that the fish screen facilities will not conflict with RWPC operations. Temporary construction easements and/or permits will also be acquired from all affected landowners before construction. Reclamation will negotiate protective measures to reduce impacts to private property, rights-of-ways, and facilities. Following construction, any damaged areas will be restored, as near as practicable, to their original condition. Construction will begin after October 15,2004 when RWPC's irrigation diversions are no longer needed. The Redlands Power Canal will be dewatered to construct the canal bypass and install the upstream and downstream bulkhead isolation structures. The Redlands Power Canal will be dewatered from November 1,2004 to April 1, 2005 for construction. If the bypass channel and isolation structures are completed prior to April 1, 2005, RWPC could divert river flows to the Redlands Power Plant to generate hydroelectric power while fish screen construction continued. Excavated material to constnict the bypass channel (about 50,000 cubic yards) will be wasted on-site in upland areas identified by RWPC on RWPC's property. Construction access will be from the existing dam and canal access road and no major road improvement will be required.
