Relief Reservoir Emigrant Wilderness
Relief is a sculptural method in which the sculpted pieces are bonded to a solid background of the same material. The term ''relief'' is from the Latin verb ''relevo'', to raise. To create a sculpture in relief is to give the impression that the sculpted material has been raised above the background plane. When a relief is carved into a flat surface of stone (relief sculpture) or wood (relief carving), the field is actually lowered, leaving the unsculpted areas seeming higher. The approach requires a lot of chiselling away of the background, which takes a long time. On the other hand, a relief saves forming the rear of a subject, and is less fragile and more securely fixed than a sculpture in the round, especially one of a standing figure where the ankles are a potential weak point, particularly in stone. In other materials such as metal, clay, plaster stucco, ceramics or papier-mâché the form can be simply added to or raised up from the background. Monumental bronze reliefs ar ...

Middle Fork Stanislaus River
The Middle Fork Stanislaus River is a tributary of the Stanislaus River in the central Sierra Nevada and Stanislaus National Forest of eastern California. Geography The river begins at the confluence of Kennedy Creek and Summit Creek in the Emigrant Wilderness. It flows initially northwest, receiving the Clark Fork from the right then turning southwest, through a deep canyon to its confluence with the North Fork Stanislaus River, forming the Stanislaus River. The river drains a watershed of in Tuolumne County, much of it within the Stanislaus National Forest. Power and water infrastructure There are four dams on the main stem of the Middle Fork – at Donnells, Beardsley, Beardsley Forebay and Sand Bar Flat. The only significant tributary impoundment is Relief Reservoir, formed by Relief Dam on Summit Creek. Middle Fork water is managed by the Spring Gap–Stanislaus hydroelectric project, owned by Pacific Gas and Electric, and the Tri-Dam project owned by the Oakdale and Sout ...

Tuolumne County
Tuolumne County (), officially the County of Tuolumne, is a county located in the U.S. state of California. As of the 2020 census, the population was 55,620. The county seat and only incorporated city is Sonora. Tuolumne County comprises the Sonora, CA Micropolitan Statistical Area. The county is in the Sierra Nevada region. The northern half of Yosemite National Park is located in the eastern part of the county. Etymology The name ''Tuolumne'' is of Native American origin and has been given different meanings, such as Many Stone Houses, The Land of Mountain Lions, and Straight Up Steep, the latter an interpretation of William Fuller, a native Chief. Mariano Vallejo, in his report to the first California State Legislature, said that the word is "a corruption of the Native American word ''talmalamne'' which signifies 'cluster of stone wigwams.'" The name may mean "people who dwell in stone houses," i.e., in caves. History Tuolumne County Boundaries One of California's ...

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Donnells Dam
Donnells Dam (National ID # CA00264) is a concrete arch dam located on the Middle Fork of the Stanislaus River in Tuolumne County, California. The water impounded by the high dam forms Donnell Lake in Stanislaus National Forest. The dam and reservoir are co-owned by the Oakdale Irrigation District and South San Joaquin Irrigation District, and the dam is one of three in the Tri-Dam Project. The other two dams in the project are Beardsley Dam and Tulloch Dam. The dam has a length of 750 feet (230 m) at its crest and a storage capacity of . Donnells Reservoir, along with the two other dams of that make up the Tri-Dam Project, currently provide water for the irrigation of about of farmland in Stanislaus and San Joaquin counties. The reservoir also generates hydroelectric power and supplies water to urban areas. History The Oakdale Irrigation District (OID) and South San Joaquin Irrigation District (SSJID) joined forces in the late 1930s to design the Tri-Dam Project in an eff ...

Dams In California
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
