Folsom South Canal

The Folsom South Canal is an aqueduct in Northern California in the United States. The canal diverts water from the American River at Nimbus Dam in Sacramento County and travels about 26.7 miles (43.0 km) in a southerly direction, terminating near Clay, about 10 miles (16 km) northeast of Lodi. The canal is operated by the U.S. Bureau of Reclamation, as part of the Auburn-Folsom South Unit of the Central Valley Project. It is contracted for irrigation, industrial and municipal water supply; formerly it provided cooling water for the Rancho Seco Nuclear Generating Station. It is also connected to the Mokelumne Aqueduct, which provides a large portion of the San Francisco Bay Area's water supply. [3]

The trapezoidal concrete canal has an average bottom width of 34 feet (10 m), an average depth of 17.8 feet (5.4 m), and a capacity of 3,500 cubic feet per second (99 m3/s). Although it was originally planned to be 69 miles (111 km) long, extending into San Joaquin County, there are currently no plans to construct the remaining sections. [1] [2]

Construction of the canal began on July 28, 1952, with the excavation of the diversion inlet channel at Nimbus Dam, then also under construction. However, work on the main section of the canal was not begun for almost 20 years. In 1970 and 1971 the Bureau of Reclamation awarded three contracts for Folsom South Canal construction to Syblon-Reid Company, Gordon H. Ball Inc., and Western Contracting Company for a total of $25,556,469. [2] The first water delivery was on June 27, 1973, and the canal was completed by the end of 1973. [2]

The canal provides water to about 7,000 acres (2,800 ha) of farmland, with $12 million in annual revenue. In 1991, water deliveries excluding irrigation amounted to 39,000-acre-foot (48,000,000 m3). [1]

The Folsom South Canal Trail, a paved hiking/biking path, runs the entire length of the canal.

Central Valley Project Flood control, energy production, and water conveyance infrastructure in California

The Central Valley Project (CVP) is a federal power and water management project in the U.S. state of California under the supervision of the United States Bureau of Reclamation (USBR). It was devised in 1933 in order to provide irrigation and municipal water to much of California's Central Valley—by regulating and storing water in reservoirs in the northern half of the state, and transporting it to the water-poor San Joaquin Valley and its surroundings by means of a series of canals, aqueducts and pump plants, some shared with the California State Water Project (SWP). Many CVP water users are represented by the Central Valley Project Water Association.

Lake Natoma

Lake Natoma is a small lake in the western United States, along the lower American River, between Folsom and Nimbus Dams in Sacramento County, California. The lake is located within the Folsom Lake State Recreation Area which is responsible for maintaining the facilities and bike trails surrounding the lake. Lake Natoma is located 15 miles east of Sacramento, and has 500 surface acres of water. The total length of lake Natoma is 4 miles.

Nimbus Dam Dam in Sacramento County, California

The Nimbus Dam is a base load hydroelectric dam on the American River near Folsom, California. Approximately 8,700 acre-feet (10,700 dam3) of water is retained by the dam. It is responsible for the impoundment of water from the American River to create the Lake Natoma reservoir. The dam stands 87 feet and spans 1,093 feet. The Nimbus powerplant consists of two generators. Each generator produces enough electrical power to power over 200,000 100-watt light bulbs, about 15,500 kilowatts of electrical power. Nimbus Dam consists of 18 radial gates, each with their own gate bays. These 18 gates today are the ones that were completed in 1955 along with the rest of the dam. Of the eighteen gates, four of them have had their coating system replaced. This protects the gates from a faster rate of corrosion. The other fourteen gates have the original coating.

Auburn Dam Dam in Near Auburn, California

Auburn Dam was a proposed concrete arch dam on the North Fork of the American River east of the town of Auburn, California, in the United States, on the border of Placer and El Dorado Counties. Slated to be completed in the 1970s by the U.S. Bureau of Reclamation, it would have been the tallest concrete dam in California and one of the tallest in the United States, at a height of 680 feet (210 m) and storing 2,300,000 acre-feet (2.8 km3) of water. Straddling a gorge downstream of the confluence of the North and Middle Forks of the American River and upstream of Folsom Lake, it would have regulated water flow and provided flood control in the American River basin as part of Reclamation's immense Central Valley Project.

The Central Utah Project is a US federal water project that was authorized for construction under the Colorado River Storage Project Act of April 11, 1956, as a participating project. In general, the Central Utah Project develops a portion of Utah's share of the yield of the Colorado River, as set out in the Colorado River Compact of 1922.

Mokelumne Aqueduct

The Mokelumne Aqueduct is a 95-mile (153 km) water conveyance system in central California, United States. The aqueduct is supplied by the Mokelumne River and provides water to 35 municipalities in the East Bay in the San Francisco Bay Area. The aqueduct and the associated dams, pipelines, treatment plants and hydroelectric system are owned and operated by the East Bay Municipal Utility District (EBMUD) and provide over 90 percent of the water used by the agency.

Minidoka Project

The Minidoka Project is a series of public works by the U.S. Bureau of Reclamation to control the flow of the Snake River in Wyoming and Idaho, supplying irrigation water to farmlands in Idaho. One of the oldest Bureau of Reclamation projects in the United States, the project involves a series of dams and canals intended to store, regulate and distribute the waters of the Snake, with electric power generation as a byproduct. The water irrigates more than a million acres (4,000 km²) of otherwise arid land, producing much of Idaho's potato crop. Other crops include alfalfa, fruit and sugar beets. The primary irrigation district lies between Ashton in eastern Idaho and Bliss in the southwestern corner of the state. Five main reservoirs collect water, distributing it through 1,600 miles (2,600 km) of canals and 4,000 miles (6,400 km) of lateral distribution ditches.

Yuma Project

The Yuma Project is a U.S. Bureau of Reclamation project built to irrigate over 68,000 acres (280 km2) of land in Yuma County, Arizona and parts of Imperial County, California. The project is designed to exploit year-round farming conditions and water from the Colorado River. It consists of the Laguna Diversion Dam, pumping plants, a power plant, a 53-mile (85 km) system of canals, 218 miles (351 km) of lateral canals, levees and drains. The project began in 1903 and the majority of the work was completed by 1915. It was the first dam and reclamation project on the Colorado River and workers had to overcome many natural and logistical obstacles to build and maintain it. The Laguna Diversion Dam was replaced by the Imperial Dam as the Project's water source between 1941 and 1948. Today, it serves 275 farms and over 94,000 people.

Kirwin Reservoir

Kirwin Reservoir is a reservoir in Phillips County, Kansas, United States. It is located next to the city of Kirwin in northern Kansas. The U.S. Bureau of Reclamation built it and continues to operate it for the purposes of flood control and area irrigation. The Kirwin National Wildlife Refuge lies on its shores.

Middle Rio Grande Project

The Middle Rio Grande Project manages water in the Albuquerque Basin of New Mexico, United States. It includes major upgrades and extensions to the irrigation facilities built by the Middle Rio Grande Conservancy District and modifications to the channel of the Rio Grande to control sedimentation and flooding. The bulk of the work was done by the United States Bureau of Reclamation and the United States Army Corps of Engineers in the 1950s, but construction continued into the 1970s and maintenance is ongoing. The project is complementary to the San Juan-Chama Project, which transfers water from the San Juan River in the Colorado River Basin to the Rio Grande. Although distribution of water from the two projects is handled through separate allotments and contracts, there is some sharing of facilities including the river itself. The ecological impact on the river and the riparian zone was the subject of extended litigation after a group of environmentalists filed Rio Grande Silvery Minnow v. Bureau of Reclamation in 1999.

Red Bluff Diversion Dam Dam in Tehama County, California

Red Bluff Diversion Dam is a disused irrigation diversion dam on the Sacramento River in Tehama County, California, United States, southeast of the city of Red Bluff. Until 2013, the dam provided irrigation water for two canals that serve 150,000 acres (61,000 ha) of farmland on the west side of the Sacramento Valley. The dam and canals are part of the Sacramento Canals Unit of the Central Valley Project, operated by the U.S. Bureau of Reclamation. In 2013, the dam was decommissioned and the river allowed to flow freely through the site in order to protect migrating fish. A pumping plant constructed a short distance upstream now supplies water to the canal system.

Auburn-Folsom South Unit

The Auburn-Folsom South Unit is a project associated with the Central Valley Project in California and is one of three units located on the American River in Northern California, the United States Bureau of Reclamation is in charge of the Central Valley Project, including this project. The initial budget for this unit was 1.5 billion dollars. This unit includes a number of dams located on the American River, and work to divert and manage water in the area. The associated features of the Auburn-Folsom South Unit include the Folsom South Canal which was designed to change the direction of water flow at the Nimbus Dam along the American River near Sacramento in Northern California, Auburn Dam which was proposed to be built in the city of Auburn, California, the Sugar Pine Dam located in Placer County, and the County Line Dam and associated features of which construction was never initiated. The South Unit was approved by law in 1965, although actual construction of the projects did not begin until 1967. Some of the projects initially proposed to be a part of the unit were never halted once construction began, or were never started at all.
