UNITED STATES DEPARTMENT OF THE INTERIOR BUREAU OF RECLAMATION Mid-Pacific Region • Sacramento, California Revised November 1980 FACT SHEET TRINITY RIVER DIVISION CENTRAL VALLEY PROJECT PURPOSE The Trinity River Division is a major part of the Central Valley Project. It provides water for irrigation, power, recreation, and fish and wild­ life conservation. Water from the Trinity River Basin is stored, regu­ lated, and diverted through a system of reservoirs, dams, powerplants, tunnels, and conduits into water-deficient areas of the Central Valley Basin. LOCATION The Trinity River Division features are located in Trinity and Shasta Counties of California. At Lewiston Dam, the Trinity River is about 1,400 feet (430 meters (m» higher in elevation and 20 miles (32 kilo­ • meters (km» west of the Sacramento River at Keswick Dam. PLAN Trinity River ~ater is stored in the 2,448,000-acre-foot (3 020 000 000­ cubic meter (m » )Clair Engle Lake behind Trinity Dam. Releases from this reservoir are utilized by a 105,556-kilowatt powerplant and reregu­ lated in Lewiston Lake about 7 miles (11 km) downstream. Lewiston Dam with the 350-kW Lewiston Powerplant regulates flows to meet the downstream requirements of the Trinity River Basin, including the Trinity River Fish Hatchery and downstream fishery. Water not released to the Trinity River Basin is diverted by Lewiston Dam through the Clear Creek Tunnel to the 141,444-kW Judge Frjncis Carr Powerhouse and then into the 241,000 acre- foot (297 300 000 m ) Whiskeytown Lake behind Whiskeytown Dam on Clear Creek, a tributary of the Sacramento River.

  • Putah Creek Watershed Watershed Assessment and Water Quality Monitoring Proposal June 28, 2004
    Napa County Putah Creek Watershed Watershed Assessment and Water Quality Monitoring Proposal June 28, 2004 Lower Chiles Valley, Napa County Putah Creek Drainage Prepared By: Phillip Blake, USDA Natural Resources Conservation Service, Napa Sandy Elles & Jennifer Kopp, Napa County Farm Bureau Dave Whitmer, Napa County Agricultural Commissioner Bob Zlomke, Napa Co. Resource Conservation District Napa County Putah Creek Watershed Group Steering Committee: Sally Kimsey Jim Frisinger Tucker Catlin Robert Craig Jack Todeschini Don Clark Advisor: Diane Dillon, Supervisor, Dist. 4 1 2 Introduction In July, 2003, the Napa County Farm Bureau organized an informational meeting of landowners and farm agency representatives, to discuss local ramifications for the removal of agricultural waste discharge waivers in the Putah Creek watershed. Following this initial exploration of information known about Irrigated Lands Waivers, the NC Farm Bureau invited farmers in the Napa County Putah Creek area to join a coalition and apply for a group waiver. The group would organize to share best management practices and conduct water quality monitoring. Since that initial meeting, representatives from Napa County Farm Bureau, USDA Natural Resouces Conservation Service, (NRCS) Napa County Resource Conservation District, (NCRCD), UC Cooperative Extension, and the Napa County Agricultural Commissioner have further studied the issue and determined that irrigated lands in the area are primarily drip-irrigated wine grape vineyards. These farm operations typically employ minimal use of chemical inputs and utilize farm cultural practices that present a very limited potential to impact downstream waters with pollutants of concern. Water quality issues have been extensively discussed and addressed through various processes, including 2 different county watershed task forces and several technical advisory bodies, since 1989.

  • The Biological Resources Section Provides Background Information
    4.5 BIOLOGICAL RESOURCES The Biological resources section provides background information on sensitive biological resources within Napa County, the regulations and programs that provide for their protection, and an assessment of the potential impacts to biological resources of implementing the Napa County General Plan Update. This section is based upon information presented in the Biological Resources Chapter of the Napa County Baseline Data Report (Napa County, BDR 2005). Additional information on the topics presented herein can be found in these documents. Both documents are incorporated into this section by reference. This section addresses biological resources other than fisheries which are separately addressed in Section 4.6. 4.5.1 SETTING REGIONAL SETTING The Napa County is located in the Coast Ranges Geomorphic Province. This province is bounded on the west by the Pacific Ocean and on the east by the Great Valley geomorphic province. A dominant characteristic of the Coast Ranges Province is the general northwest- southeast orientation of its valleys and ridgelines. In Napa County, located in the eastern, central section of the province, this trend consists of a series of long, linear, major and lesser valleys, separated by steep, rugged ridge and hill systems of moderate relief that have been deeply incised by their drainage systems. The County is located within the California Floristic Province, the portion of the state west of the Sierra Crest that is known to be particularly rich in endemic plant species (Hickman 1993, Stein et al. 2000). LOCAL SETTING The County’s highest topographic feature is Mount St. Helena, which is located in the northwest corner of the County and whose peak elevation is 4,343 feet.

  • Trinity Division, Central Valley Project
    Mid-Pacific Region Trinity Division, Central Valley Project Headwaters of the Trinity River originate deep within the remote and rugged Trinity Alps. The Trinity Alps watershed generates an average annual water runoff of about 1,250,000 acre-feet at Lewiston Reservoir. Trinity Dam and Reservoir Trinity Dam regulates flows on the Trinity River and stores water for irrigation within Trinity Reservoir. Completed in 1962, it is an earth fill structure, 538 feet high, with a crest length of 2,450 feet. Trinity Reservoir has a storage capacity of 2,448,000 acre-feet. The lake offers recreation facilities for camping, boating, water skiing, swimming, fishing, and hunting. Trinity Dam and Reservoir Trinity Powerplant Trinity Powerplant is a peaking plant with generated power dedicated to meeting the needs of the project facilities. Any remaining energy is then marketed to various preference customers in northern California, with Trinity County having first preference. Trinity Dam’s hydroelectric powerplant began operation in 1964 with a capacity of 100,000 kilowatt (kW) for its two generators. In the mid-1980’s Reclamation uprated both generators by 20,000 kW by using advancements in high voltage technology bringing the current total capacity to 140,000 kW. Trinity Powerplant Lewiston Dam and Lake Lewiston Dam, about seven miles downstream from Trinity Dam, creates an afterbay to Trinity Powerplant. It regulates flows to the Trinity River and diverts water by means of Clear Creek Tunnel to Whiskeytown Lake. Lewiston Dam is an earthfill structure, 91 feet high and 754 feet long, forming a reservoir with a capacity of 14,660 acre-feet.
