Upper Columbia Alternative Flood Control and Fish Operations, Libby and Hungry Horse Dams, MT
In accordance with the requirements of the National Environmental Policy Act, the U.S. Army Corps of Engineers (USACE), Seattle District, and the Bureau of Reclamation (Reclamation), Pacific Northwest Region, have prepared a Draft Environmental Impact Statement (DEIS) to evaluate the effects of alternative flood control at Libby Dam on the Kootenai River and at Hungry Horse Dam on the South Fork Flathead River in western Montana. USACE and Reclamation are making the document available to the public for review and comment through a Notice of Availability published in the Federal Register. The overall goal of the DEIS is to evaluate effects of alternative dam operations that are intended to provide reservoir and flow conditions at and below Libby and Hungry Horse Dams for anadromous and resident fish listed as threatened or endangered under the Endangered Species Act (ESA), consistent with authorized project purposes, including maintaining the current level of flood control benefits.
South Delta Improvements Program, Sacramento-San Joaquin Bay Delta, California
The Bureau of Reclamation (Reclamation) and the California Department of Water Resources (DWR) have made available for public review and comment the Draft EIS/EIR for the South Delta Improvements Program (SDIP). The proposed SDIP would (1) construct and operate a fish control gate at the Head of Old River; (2) construct and operate up to 3 flow control gates (one each in Middle River, Grant Line Canal, and Old River, near the Tracy Pumping Plant) to maintain adequate water quality and water levels available for agricultural diversions in the south Delta, downstream of the Head of Old River; (3) dredge various channels within the south Delta to improve conveyance; (4) construct extensions of up to 24 shallow agricultural diversions; (5) increase water deliveries by increasing the maximum diversion through the existing intake gates at Clifton Court Forebay to 8,500 cubic feet per second; and (6) implement an interim operations regime between December 15 and March 15 until the permanent gates are fully operable.
