Engineered Valve Solutions Part IV Click here if the newsletter is not shown correctly. You have come to know VAG as a reliable partner for engineered valve solutions for dams and hydropower application. Today we want to present you another case study with large size valves installed in California: VAG Installation at Cherry Dam Two (2) existing 66-inch Hollow Jet valves and actuation systems have been replaced by two (2) new 66-inch VAG Howell-Bunger® Discharge Valves complete with discharge hood, support bracing, and electric actuation system. View into 145“ discharge hood during installation works Cherry Lake (also known as Lake Lloyd) is an artificial lake in the Stanislaus National Forest of Tuolumne County, California USA. The lake has a capacity of 273,500 acre·ft and is formed by Cherry Valley Dam on Cherry Creek. The dam is composed of earth and rock-fill and has a height of 315 ft above the original streambed. It was built by San Francisco City and County and the Modesto Irrigation District and Turlock Irrigation District. It was completed in 1956. The lake stores water for the Hetch Hetchy Project, which supplies drinking water to the San Francisco Bay Area, Modesto and Turlock districts. Both 66” VAG Howell-Bunger® Discharge Valves during operation The design of project to replace the bottom outlet valves was announced in September of 2013. VAG offered specification and design advice and was listed in the specification for the project which bid 3 years later in 2016. Due to the large greater San Francisco population served, earthquake zones and critical water storage in the California High Sierra Mountains, the owner was in need of a high quality valves. VAG’s technical solution included the updated and innovative KSSplus Howell-Bunger® Valve design. After a detailed review VAG was selected for the supply of 2 pcs. VAG 66” KSSplus Howell-Bunger® Discharge Valves completely manufactured from stainless steel with 100” venting system and 145” discharge hood. 3D model of VAG KSSplus Howell-Bunger® Discharge Valves including venting system and hood The VAG engineering, manufacturing and QA/QC teams insured that the valve met all customer quality requirements, including 13 separate witness inspections. Upon completion of the manufacturing and final witness inspection, the customer reported that the VAG valve met and surpassed all expectations and was indeed a very impressive valve. After commissioning the owner was similarly impressed with the reliable function of the VAG KSSplus Howell-Bunger® Discharge Valves. Meanwhile both valves have been working reliably for more than one year. 66“ VAG KSSplus Howell-Bunger® Discharge Valve on VAG test bench in German facility A video is available in Youtube Visit us at this show 23 – 25 July 2019 HydroVision 2019 Portland, Oregon, USA Our Regional Sales Director for North America will be pleased to provide you further details.

  • Mineral Resources of the Emigrant Basin Primitive Area, California
    Mineral Resources of the Emigrant Basin Primitive Area, California By E. W. TOOKER, H. T. MORRIS, U.S. GEOLOGICAL SURVEY, and PAUL V. FILLO, U.S. BUREAU OF MINES With a section on GEOPHYSICAL STUDIES By H. W. OLIVER, U.S. GEOLOGICAL SURVEY STUDIES RELATED TO WILDERNESS PRIMITIVE AREAS GEOLOGICAL SURVEY BULLETIN 1261-G An evaluation of the mineral potential of a part of the central Sierra Nevada UNITED STATES GOVERNMENT PRINTING OFFICE, WASHINGTON : 1970 UNITED STATES DEPARTMENT OF THE INTERIOR WALTER J. HICKEL, Secretary GEOLOGICAL SURVEY William T. Pecora, Director For sale by the Superintendent of Documents, U.S. Government Printing Office Washington, D.C. 20402 In accordance with the provisions of the Wilderness Act (Public Law 88-577, Sept. 3,1964) and the Conference Report on Senate bill 4, 88th Congress, the U.S. Geological Survey and the U.S. Bureau of Mines are making mineral surveys of wilderness and primitive areas. Areas officially designated as "wilderness," "wild," or "canoe," when the act was passed were incorporated into the National Wilderness Preservation System. Areas classed as "primi­ tive" were not included in the Wilderness System, but the act provides that each primitive area should be studied for its suitability for incorporation into the Wilderness System. The mineral surveys constitute one aspect of the suitability studies. This bulletin reports the results of a mineral survey in the Emigrant Basin primitive area, California. The area discussed in the report corresponds to the area under consideration for wilderness status. It is not identical with the original Emigrant Basin Primi­ tive Area as defined because modifications of the bound­ ary have been proposed for the area to be considered for wilderness status.

  • I Integrated Water Operations in California: Hydropower, Overdraft
    Integrated Water Operations in California: Hydropower, Overdraft, and Climate Change By MUSTAFA SAHIN DOGAN B.S. (Dokuz Eylul University, Izmir, Turkey) 2011 THESIS Submitted in partial satisfaction of the requirements for the degree of MASTER OF SCIENCE in Civil and Environmental Engineering in the OFFICE OF GRADUATE STUDIES of the UNIVERSITY OF CALIFORNIA DAVIS Approved: _____________________________________ Jay R. Lund, Chair _____________________________________ Samuel Sandoval Solis _____________________________________ Jonathan Herman Committee in Charge 2015 i Abstract Several management and climate cases are evaluated with the updated CALVIN, a hydro-economic optimization model of California’s inter-tied water supply infrastructure. Updates to the CALVIN model include new projected 2050 agricultural target demands and scarcity penalties, improvements to network- flow representation, especially agricultural, urban, and wildlife refuge demands, and extended surface and ground water hydrology, now covering an 82-year historical inflow hydrology. A new energy price scheme is applied to CALVIN, which incorporates hourly energy price variations into monthly CALVIN operations. Using one constant average price for a month underestimates hydropower revenue and overestimates pumping costs. Hourly-varying moving average prices improved representation of hydropower revenue without creating significant scarcities to agricultural and urban water users. Effects of ending long-term groundwater overdraft in the Central Valley are evaluated with several management cases using CALVIN. The cases include effects of Delta outflow and Delta exports from a “no overdraft” policy. The least cost overdraft that minimizes groundwater pumping and scarcity costs is calculated for the 82- year period. Prohibiting Delta exports result in severe water scarcities south of the Delta. Water operations are more economical when overdraft is ended with adaptations, such as more Delta exports, increased groundwater banking, and water trades, than historical operations with overdraft.

The impact section (Section 5.3.1.2) provides a description of the changes in stream flow and reservoir water levels that would result from implementation of the WSIP. 5.3.1.1 Setting The Tuolumne River flows from the crest of the Sierra Nevada westward to its confluence with the San Joaquin River. The San Joaquin River flows north to the Sacramento–San Joaquin Delta. Water from the Delta discharges to the San Francisco Bay Estuary and the Pacific Ocean. Surface water bodies in the Tuolumne River system that could be affected by the proposed program include the Tuolumne River, Cherry Creek, Eleanor Creek, and a quarter-mile reach of Moccasin Creek. Several reservoirs could be affected by the WSIP, including Hetch Hetchy Reservoir, Lake Lloyd, Lake Eleanor, and Don Pedro Reservoir. Because the Tuolumne River drains to the San Joaquin River and the Sacramento–San Joaquin Delta, these water bodies could also be affected by the WSIP.

  • Hetch Hetchy Valley
    National Park Service Yosemite U.S. Department of the Interior Yosemite National Park Hetch Hetchy Valley Hetch Hetchy Valley on August 11, 1911. Photo by Matt Ashby Wolfskill, courtesy of the Library of Congress. Introduction Hidden in Yosemite National Park’s peaceful northwest corner, Hetch Hetchy Valley is a treasure worth visiting in all seasons. In spring, two of North America’s tallest waterfalls plummet spectacularly over thousand-foot granite cliffs. The dramatic cliffs surrounding these waterfalls add to the grandeur that John Muir compared to the more well known Yosemite Valley. In 1870, Muir called Hetch Hetchy Valley “a wonderfully exact counterpart of the great Yosemite.” In the early spring through late fall, visitors have easy access to a vast wilderness filled with high-country lakes, streams, and wildlife. A rare snowy winter day gives adventuresome visitors a chance to explore on skis or snowshoes. Early History People have lived in Hetch Hetchy Valley The lifestyle of first inhabitants depended for more than 6,000 years. American on the natural resources of the land. They Indian cultures were prominent before would gather seeds and plants, hunt, and the 1850s when the first Euro-Americans trade. Meadow plants were particularly came looking for gold and a place to graze valuable resources to these tribes. Today, livestock. The valley name probably derived descendants of these people still use from the Miwok word, hatchhatchie, which milkweed, deergrass, bracken fern, willow, means “edible grasses.” Miwok names are and other plants for a variety of uses still used for features, including Tueeulala including baskets, medicines, and string.
