The Los Angeles Aqueduct system, comprising the Los Angeles Aqueduct and the Second Los Angeles Aqueduct, is a water conveyance system, built and operated by the Los Angeles Department of Water and Power. The Owens Valley aqueduct was designed and built by the city's water department, at the time named The Bureau of Los Angeles Aqueduct, under the supervision of the department's Chief Engineer William Mulholland. The system delivers water from the Owens River in the eastern Sierra Nevada mountains to Los Angeles.
Garrison Dam is an earth-fill embankment dam on the Missouri River in central North Dakota, U.S. Constructed by the U.S. Army Corps of Engineers from 1947 to 1953, at over 2 miles (3.2 km) in length, the dam is the fifth-largest earthen dam in the world. The reservoir impounded by the dam is Lake Sakakawea, which extends to Williston and the confluence with the Yellowstone River, near the Montana border.
Lake Nacimiento is an 18-mile (29 km) long lake on the Nacimiento River in northern San Luis Obispo County, California. The lake contains many arms including Snake Creek and Dip Creek, nearer the dam, and the central Las Tablas and Franklin Creeks.
Prado Dam is an earth-fill dry dam across the Santa Ana River at the Chino Hills near Corona, California in Riverside County with the resulting impounded water creating Prado Flood Control Basin reservoir. The U.S. Army Corps of Engineers built the dam in Lower Santa Ana River Canyon. Its primary purpose is flood control and it is the downstream element of the Santa Ana River's flood control system, which is a natural constriction about 30.5 mi (49.1 km) upstream from the ocean. The area upstream from the dam contains 2,255 sq mi (5,840 km2) of the watershed's 2,650 sq mi (6,900 km2). The dam's construction was authorized in 1936 and the flood of 1938 demonstrated its necessity. Construction was completed in 1941. Prado Flood Control Basin also provides water storage for groundwater recharge operations.
Whittier Narrows Dam is a 56-foot tall earth dam on the San Gabriel River and the smaller, parallel Rio Hondo. The dam is located, as the name implies, at the Whittier Narrows. It provides water conservation storage and is also the central element of the Los Angeles County Drainage Area (LACDA) flood control system. Its reservoir has a capacity of 67,060 acre⋅ft (82,720,000 m3).
Dworshak Dam is a concrete gravity dam in the western United States, on the North Fork of the Clearwater River in north central Idaho. In Clearwater County, the dam is located approximately four miles (6 km) northwest of Orofino and impounds the Dworshak Reservoir for flood control and hydroelectricity generation.
Santa Margarita is a town and census-designated place located in San Luis Obispo County, California. It was founded in 1889 near Cuesta Peak and San Luis Obispo along State Route 58. The town's name comes from the Mexican Alta California land grant of Rancho Santa Margarita. It is home to the Santa Margarita de Cortona Asistencia site. The population was 1,259 at the 2010 census.
Santa Margarita Lake, also called Salinas Reservoir, is a lake several miles southeast of the town of Santa Margarita in San Luis Obispo County, California. The lake was created by the building of Salinas Dam on the southern end of the Salinas River, very close to the river's origin in the Santa Lucia Range.
Twitchell Reservoir is a reservoir in southern San Luis Obispo County and northern Santa Barbara County in California. The reservoir has a capacity of 197,756 acre⋅ft (243,928,000 m3) and is formed by Twitchell Dam on the Cuyama River about 66 miles (106 km) from its headwaters in the Chumash Wilderness Area. About 7 miles (11 km) below the dam, outflow joins the Sisquoc River near Gary, CA to form the Santa Maria River.
Camp San Luis Obispo is the original home of the California Army National Guard. It served as an Infantry Division Camp and Cantonment Area for the United States Army during World War II.
Owyhee Dam is a concrete arch-gravity dam on the Owyhee River in Eastern Oregon near Adrian, Oregon, United States. Completed in 1932 during the Great Depression, the dam generates electricity and provides irrigation water for several irrigation districts in Oregon and neighboring Idaho. At the time of completion, it was the tallest dam of its type in the world. The dam is part of the Owyhee Dam Historic District, which is listed on the National Register of Historic Places.
John Redmond Reservoir is a reservoir on the Neosho River in eastern Kansas. Built and managed by the U.S. Army Corps of Engineers, it is used for flood control, recreation, water supply, and wildlife management. It borders the Flint Hills National Wildlife Refuge to the northwest.
Santa Fe Dam is a flood-control dam on the San Gabriel River located in Irwindale in Los Angeles County, California, United States. For most of the year, the 92-foot (28 m)-high dam and its reservoir lie empty, but can hold more than 45,000 acre-feet (56,000,000 m3) of water during major storms. During the dry season, the basin behind the dam is used for groundwater recharge, as well as various recreational activities.
Morris Dam is a concrete gravity dam across the San Gabriel River in the U.S. state of California. It impounds Morris Reservoir, directly downstream of San Gabriel Dam.
Lake Hudson, also known as Markham Ferry Reservoir, is a man-made reservoir in Mayes County, Oklahoma, United States, about 2 miles (3.2 km) northwest of Locust Grove, Oklahoma and 8 miles (13 km) southeast of Pryor, Oklahoma. It was created by the completion of the Robert S. Kerr Dam on the Grand River in 1964. It is managed by the Grand River Dam Authority (GRDA).
The Big Creek Hydroelectric Project is an extensive hydroelectric power scheme on the upper San Joaquin River system, in the Sierra Nevada of central California. The project is owned and operated by Southern California Edison (SCE). The use and reuse of the waters of the San Joaquin River, its South Fork, and the namesake of the project, Big Creek – over a vertical drop of 6,200 ft (1,900 m) – have over the years inspired a nickname, "The Hardest Working Water in the World".
Nacimiento Dam is a dam on the Nacimiento River about 10 miles (16 km) northwest of Paso Robles, California in the United States. The primary purpose of the dam is to provide groundwater recharge for agriculture in Monterey County and northern San Luis Obispo County supported by the Salinas Valley aquifer, as well as flood control, domestic water supply, and hydropower. It forms Lake Nacimiento, popular for boating, fishing and camping, and known locally as the "Dragon Lake" due to its shape.
The Upper North Fork Feather River Project is a hydroelectric scheme in the Sierra Nevada of California, within Lassen and Plumas Counties. The project consists of three dams, five power plants, and multiple conduits and tunnels in the headwaters of the North Fork Feather River, a major tributary of the Feather—Sacramento River systems. The total installed capacity is 362.3 megawatts (MW), producing an annual average of 1,171.9 gigawatt hours (GWh). The project is also contracted for the delivery of irrigation water between March 31 and October 31 of each year. The project is owned and operated by Pacific Gas and Electric Company.
The Potomac River basin reservoir projects were U.S. Army Corps of Engineers programs that sought to regulate the flow of the Potomac River to control flooding, to assure a reliable water supply for Washington, D.C., and to provide recreational opportunities. Beginning in 1921 the Corps studied a variety of proposals for an ambitious program of dam construction on the Potomac and its tributaries, which proposed as many as sixteen major dam and reservoir projects. The most ambitious proposals would have created a nearly continuous chain of reservoirs from tidewater to Cumberland, Maryland. The 1938 program was focused on flood control, on the heels of a major flood in 1936. The reformulated 1963 program focused on water supply and quality, mitigating upstream pollution from sewage and coal mine waste.
Cuesta Pass or La Cuesta Pass, colloquially referred to as simply the grade, is a low mountain pass in San Luis Obispo County on California's Central Coast. It crosses the southern Santa Lucia Range at an altitude of 1,522 feet (464 m), and connects San Luis Obispo, roughly 5 miles (8.0 km) to the south, with Atascadero, Paso Robles, and the Salinas Valley to the north. It is traversed by U.S. Route 101 and the Coast Line of the Union Pacific Railroad, and is better known for the long slope up to the pass from San Luis Obispo, in the canyon of San Luis Obispo Creek, which is redundantly named the "Cuesta Grade".
