U.S. Department of the Interior Bureau of Reclamation Mid-Pacific Region Folsom50Booklet 1 5/10/2006, 10:22 AM This booklet was printed in cooperation with Folsom50Booklet 2 5/10/2006, 10:22 AM U.S. Department of the Interior Bureau of Reclamation Mid-Pacific Region Folsom50Booklet 3 5/10/2006, 10:22 AM Dedication I am pleased to offer my congratulations as Folsom Dam celebrates its 50th Anniversary. For half a century, through drought and flood, Folsom Dam has managed American River flows for the benefit of people, farms, industry, and the environment. Since its completion in 1956, it has effectively controlled flooding. Even several months before its final William E. Rinne completion, Folsom Dam prevented flood Acting Commissioner damage when a major tropical storm Bureau of Reclamation triggered rapid snowmelt. The dam impounded so much runoff that Folsom Lake filled in one week rather than the one year anticipated by engineers. It is estimated that this magnificent dam has prevented more than $5 billion in flood damage to downstream agricultural and urban areas, a testament to the foresight of the men and women who envisioned and built it. Today, Folsom Dam provides 500,000 acre-feet of water for irrigation and urban uses annually. It plays an important role in fisheries enhancement and water quality improvement in the San Francisco Bay-Delta. The dam also provides clean, renewable electricity. In 2005, it produced more than 690 million kilowatt hours. As a recreational facility, Folsom Lake is one of the most visited recreation areas operated by the California Department of Parks and Recreation. -

3A.12 Parks and Recreation - Land
3A.12 PARKS AND RECREATION - LAND The two local roadway connections from the Folsom Heights property off-site into El Dorado Hills would not generate direct increases in population that could result in additional demand for parkland facilities in El Dorado County. Therefore, the “Affected Environment” does not contain a discussion of conditions in El Dorado County related to parks and recreation. 3A.12.1 AFFECTED ENVIRONMENT REGIONAL ENVIRONMENT Folsom Lake Folsom Lake State Recreation Area (SRA), located approximately 5 miles north of the SPA, serves the greater Sacramento area for recreation in the form of camping, hiking, biking, boating, and other outdoor recreation activities. The lake also hosts bass fishing tournaments that frequently draw fishermen from throughout the state. California State Parks manages the Folsom Lake SRA, which includes Folsom Lake and the surrounding facilities. The lake features approximately 75 miles of shoreline and 80 miles of trails that provide opportunities for hiking, horseback riding, nature studies, camping, and picnicking. There are seven major recreation areas with facilities located around the lake. The Folsom Lake SRA, including Folsom Lake, is one of the most heavily used recreational facilities in the California State Park system, with 2 to 3 million visitor days per year. Approximately 75% of the annual visitations to the Folsom Lake SRA occur during the spring and summer, and many (85%) of the Folsom Lake SRA activities are water dependent. The Lake Natoma sub-unit of the Folsom Lake SRA is located adjacent to the City of Folsom, between Hazel Avenue and Folsom Dam, upstream from the Sacramento County-operated portion of the American River Parkway. -

NOTICE of PREPARATION Waterfix EIR for WSC Amendments
July 13, 2018 NOTICE OF PREPARATION Environmental Impact Report For the Proposed SWP Water Supply Contract Amendments for Water Management and California WaterFix July 13, 2018 INTRODUCTION Pursuant to the California Environmental Quality Act (CEQA), the Department of Water Resources (DWR) will be the Lead Agency and will prepare an Environmental Impact Report (EIR) for the proposed State Water Project Water Supply Contract Amendments for Water Management and California WaterFix (proposed project). As more fully discussed below, this proposed project includes amending certain provisions of the State Water Resources Development System (SWRDS) Water Supply Contracts (Contracts). SWRDS (defined in Water Code Section 12931), or more commonly referred to as the State Water Project (SWP), was enacted into law in the Burns-Porter Act, passed by the Legislature in 1959 and approved by the voters in 1960. DWR constructed and currently operates and maintains the SWP, a system of storage and conveyance facilities that 1 provide water to 29 State Water Contractors known as the Public Water Agencies (PWAs). These PWAs include local water agencies and districts legislatively enabled to serve irrigation, municipal and industrial water supply customers or retail water supply 1 The State Water Project Public Water Agencies include Alameda County Flood Control and Water Conservation District (Zone 7), Alameda County Water District, Antelope Valley-East Kern Water Agency, Castaic Lake Water Agency, City of Yuba City, Coachella Valley Water District, County -
PIT Tag Monitoring for Emigrating Juvenile Chinook Salmon at Three Flow Conditions
PIT Tag Monitoring for Emigrating Juvenile Chinook Salmon at Three Flow Conditions Introduction Historically, California’s upper San Joaquin River (SJR) supported stable populations of fall- and spring-run Chinook salmon (Oncorhynchus tshawytscha). However, both populations were extirpated from the system in the mid-twentieth century following the development of Friant Dam (Moyle 2002). In response to the San Joaquin River litigation Settlement, the San Joaquin River Restoration Program (SJRRP) has implemented an objective to restore a naturally reproducing and self-sustaining population of Chinook salmon, as well as other fishes, in the system. Because the anadromous life-cycle of SJR Chinook salmon requires conveyance of juveniles from a riverine system to the Pacific Ocean to support the return of spawning adults, meeting this objective requires the consideration of environmental conditions and a connected river system. Though there are likely a multitude of environmental parameters that impact emigrating juvenile salmon, flow regime and predation are often cited as having a significant effect on travel speed and survivability (Raymond 1968; Berggren and Filardo1993; Michel et al. 2013). Flows in the SJR are highly regulated as means to support agricultural production, and non-native piscivorous fish in the restoration reach tend to occur more frequently downstream of Reach 1 (Gravelly Ford to confluence of Merced River; SJRRP 2013 I&M Report). Anecdotal evidence collected during SJRRP fish inventory and monitoring efforts suggests many of the non-native piscivores tend to reside in anthropogenic altered habitats (e.g., mine pits, altered channels, etc), which may pose a challenge to emigrating salmon. River flow conditions and water temperatures were managed during spring releases to elicit downstream fish movement with pulse flows and receding flows benches to avoid stranding. -
PAP-732 Control of Release Water Temperatures in Reclamation's
PAP-732 Control of Release Water Temperatures in Reclamation's Central Valley Project by Perry L. Johnson Presented in Japan by Darrell W. Webber November 1991 HYDRAULICS BRANCH OFFICIAL FILE COPY CONTROL OF RELEASE WATER TEMPERATURES IN RECLAMATION'S CENTRAL VALLEY PROJECT by Darrell W. Webber Assistant Commissioner-Engineering and Research United States Bureau of Reclamation INTRODUCTION California's Central Valley Basin includes two major watersheds, the Sacramento River on the north and the San Joaquin River on the south (figure 1). The combined watersheds extend nearly 800 kilometers (500 miles) in a northwest-southeast direction and range from about 100 to 160 kilometers (60 to 100 miles) in width. The valley floor occupies about one-third of the basin; the other two thirds are mountainous. The Sacramento River and its tributaries flow southward, draining the northern part of the basin. The San Joaquin River and its tributaries flow northward, draining the central southern portion. These two river systems join at the Sacramento-San Joaquin Delta, flow into San Francisco Bay and the Pacific Ocean. The Central Valley Project, one of the United States major water developments, extends over much of the basin. Although developed primarily for irrigation, this multiple-purpose project also provides flood control, improves Sacramento River navigation, supplies domestic and industrial water, generates electric power, creates opportunities for recreation, controls salt water encroachment, and conserves fish and wildlife. The project annually delivers between 3.7 billion and 4.9 billion cubic meters (3 and 4 million acre-feet) of water for irrigation use on nearly 8 billion square meters (2 million acres) of land. -

Chapter 2. Project Update/Activities U.S
Chapter 2 Project Update/Activities since Publication of the Draft EIR/EIS Chapter 2 Project Update/Activities since Publication of the Draft EIR/EIS This chapter is intended to provide an update on various aspects of the project that have changed since issuance of the draft EIR/EIS on August 8, 2003. Many of these changes are a result of comments received on the draft EIR/EIS during the comment period, which ended December 15, 2003. Changes to the project are presented in the list below, followed by a more detailed description of each. 1. Modifications to the layout and configuration of the intake facilities 2. Site identification for Zone 40 water treatment plant 3. Revised modeling and coordinated operation agreement assumptions 4. Water contract settlement agreements None of these changes results in new impacts. In some cases they result in a reduction of severity of impacts identified in the draft EIR/EIS. A revised summary of impacts and mitigation measures is provided at the end of this chapter in Tables S-1, S-2, and S-3. Table S-1 summarizes the significant environmental impacts and Table S-2 summarizes the less-than-significant environmental impacts of the FRWP alternatives. Table S-3 summarizes significant cumulative impacts. The tables are organized to present impacts by environmental topic area and to indicate the significance of each impact, available mitigation measures, and the significance of each impact if mitigation is implemented. Responsibility for Project Implementation As noted in Chapter 1 of the draft EIR/EIS, FRWA is a joint powers agency formed by the Sacramento County Water Agency and East Bay Municipal Utility District.
