This Administrative Draft report is subject to change. The report assesses potential project effects on fish and wildlife resources and provides preliminary recommendations on how to avoid or minimize adverse effects. Reclamation has addressed many of U.S. Fish and Wildlife Service (USFWS) comments and will continue working to resolve additional comments on an ongoing basis. Reclamation is committed to continue working with the USFWS throughout the Shasta Lake Water Resources Investigation. 3 Draft – June 2013 Shasta Lake Water Resources Investigation This page left blank intentionally. 4 Draft – June 2013 United States Department of the Interior Fish and Wildlife Service Draft Fish and Wildlife Coordination Act Report for the SHASTA LAKE WATER RESOURCES INVESTIGATION Prepared for: U.S. BUREAU OF RECLAMATION SACRAMENTO, CALIFORNIA Prepared by: U.S. FISH AND WILDLIFE SERVICE SACRAMENTO FISH AND WILDLIFE OFFICE SACRAMENTO, CALIFORNIA June 2008 Administrative Draft—Subject to change EXECUTIVE SUMMARY This document constitutes the U. S. Fish and Wildlife Service’s (Service) Fish and Wildlife Coordination Act (FWCA) report to the U. S. Bureau of Reclamation (Reclamation) for the Shasta Lake Water Resources Investigation (SLWRI) (Project). The FWCA requires Federal agencies proposing water resource development projects or involved in issuance of related permits or licenses to consult with the Service and provide equal consideration to the conservation, rehabilitation, and enhancement of fish and wildlife resources with other project purposes. The findings of this report are based on information provided in the December 2006 and May 2007 Plan Formulation Report (PFR) (USBR 2006a, 2007a), available data, field investigations, and results of biological surveys (e.g., North State Resources [NSR] 2004 and Lindstrand 2007). Our report addresses the proposed Project-related beneficial and adverse effects on fish and wildlife resources and provides recommendations for Project implementation. Reclamation is the Federal lead agency for the SLWRI, pursuant to the National Environmental Policy Act (NEPA). In 2000, as a result of increases in demands for water supplies, and attention to ecosystem needs in the Central Valley of California, the Mid-Pacific Region of Reclamation reinitiated a feasibility-scope investigation to evaluate the potential of enlarging Shasta Dam. The SLWRI is being conducted under the general authority of Public Law 96-375 and the CALFED Bay-Delta Authorization Act, also known as Public Law 108-361. The SLWRI is designed to evaluate the feasibility of expanding the capacity of Shasta Reservoir for improved anadromous fish survival and improved water supply reliability, and to address other related resource needs in the primary and extended study areas. The primary study area as defined in the SLWRI PFR (USBR 2007) includes the following areas (see Appendix A, Plate 1): • Shasta Lake and tributaries (see Appendix A, Plate 2); • Keswick Reservoir; • Sacramento River between Keswick Dam and Red Bluff Diversion Dam (RBDD); • Areas surrounding Shasta Lake that would be inundated by raising Shasta Dam (Inundation Zone). The Service believes that the primary study area should be expanded to include areas above the Inundation Zone that would be impacted by dam construction activities and the relocation of campgrounds, marinas, roads, bridges, and other facilities. Additionally, the primary study area should be expanded to include the lower reaches of the tributaries to the Sacramento River between Keswick Dam and RBDD. These tributaries are important to the mainstem Sacramento River because of their significance in recruiting gravel and large woody debris, their importance for providing rearing habitat for salmonids (Maslin et al. 1996, 1997, 1998, 1999), and the potential for riparian restoration of the lower reaches of these tributaries within the SLWRI. Additionally, these tributaries may be affected by further downcutting and disconnection from the floodplain as a result of the reduction in flood flows in the mainstem Sacramento River with the proposed enlarging of Shasta Dam in the SLWRI. Administrative Draft – Subject to change ii The extended study area as defined in the SLWRI PFR (USBR 2007) includes the following areas: • Sacramento River downstream from RBDD, including parts of the American River basin; • Sacramento – San Joaquin Delta (Delta), including parts of the lower San Joaquin River; • Water service areas of the Central Valley Project (CVP) and State Water Project (SWP) that may be affected by operational changes at Shasta Dam and Reservoir. The Service believes that the extended study area should include not only the water service areas of the CVP and SWP, but also the areas downstream of CVP and SWP dams that could be affected by operational changes due to an enlarged Shasta Dam (e.g., Oroville Dam and the lower Feather River; Folsom Dam and the lower American River) (see Appendix A, Plate 3). Additionally, the extended study area should include the CALFED water storage projects currently being evaluated for construction in the future (e.g., Sites Reservoir, Los Vaqueros Reservoir, and Temperance Flat); likewise, the proposed raising of Shasta Dam should be included within planning for these future CALFED water storage projects. The primary planning objectives for the SLWRI are increasing Water Supply Reliability and Anadromous Fish Survival. The secondary planning objectives for the SLWRI are Ecosystem Restoration, Flood Damage Reduction, Increased Hydropower Generation, and Recreation. Table 1 summarizes the primary and secondary planning objectives of the SLWRI and the resource management measures that were retained to address the planning objectives as currently defined in the May 2007 PFR (USBR 2007). However, many of the resource management measures that were “retained,” including the three identified in Table 1, do not appear in the SLWRI alternatives as currently defined. The planning objectives were developed for the SLWRI based on identified water resources problems, needs, and opportunities, and information contained in the August 2000 CALFED Record of Decision (ROD). Resource management measures are features or activities that address a specific planning objective. The SLWRI developed a No Action Alternative and five comprehensive alternative plans (CPs) based on comments received on the Initial Alternatives Information Report, input from the public scoping process, and continued coordination. The various CPs call for raising Shasta Dam 6.5, 12.5, or 18.5 feet and modifying the temperature control device (TCD) to improve delivery of cold water to anadromous fish spawning and rearing habitat. The CPs are as follows: • CP1 – 6.5-Foot Dam Raise • CP2 – 12.5-Foot Dam Raise • CP3 – 18.5-Foot Dam Raise • CP4 – 18.5-Foot Dam Raise, Anadromous Fish Focus o 378,000 acre-feet (af) dedicated for cold water storage to increase the volume of cold water available to the TCD Administrative Draft – Subject to change iii Table 1.
