The Delta–Mendota Canal ends at Mendota Pool, on the San Joaquin River near the city of Mendota, 30 mi (48 km) west of Fresno. Occasionally, water from O'Neill Forebay is released into the canal. The water is pumped from the canal into O'Neill Forebay, and then is pumped into San Luis Reservoir by the Gianelli Pumping-Generating Plant. The plant is named to honor a pioneer in water management for the San Joaquin Valley, and was president of the San Luis and Delta-Mendota Water Association for two decades. With the use of two 15 foot diameter pipes, six 22,500-horsepower motors, roughly 8,500 Acre-feet (AF) of water from the Delta can be transported southward daily, after being lifted nearly 200 feet. Water is extracted from the southern portion of the San Joaquin Delta, and pumped to contractors in the San Joaquin Valley, San Benito and Santa Clara counties to meet urban and agricultural demands. The pumping station is 60 miles (96 km) to the southeast from the City of San Francisco, in the rural community of Byron, California, near the city of Tracy. Bill Jones Pumping Plant, formerly known as the Tracy Pumping Plant (TPP). This flow reversal confuses migratory fish, and brings saline water.Īn important feature of the Central Valley Project, with regards to directing water southward through the Delta–Mendota Canal is the C.W. During relatively dry years and a high exportation rate, flow of the San Joaquin River has been reversed. The pumping plants in the Delta Division have serious impacts on the flow of the Delta and San Joaquin River Basin. General work shifts consisted of 3 daily shifts, twenty-one hours a day, 6 days a week. : 15 Other contractors were the Columbia Pumping Plant, Mowry Pumping Plant, United Concrete Pipe Corporation, Western Contracting Corporation, A.

The Delta–Mendota Canal is also a key feature to the Delta Division Project which is managed by the Bureau of Reclamation, to minimize salt intrusion from the San Francisco Bay. The United States Bureau of Reclamation and the San Luis Delta Mendota Water Authority are responsible for maintaining the water quality that is discharged at the south end of the canal. With the use of the Tracy Pumping Plant, water from the Sacramento River would be diverted into the Delta–Mendota Canal. The Delta–Mendota Canal was approved for the exchange of water rights in the downstream portion of the San Joaquin River. The Friant-Kern Canal east of Fresno was built to distribute water through the eastern parts of the Central Valley, however, altered the natural flows of the San Joaquin River between the Friant Dam and confluence of the Merced River. In 1937 the Central Valley Project was approved by Congress to deliver freshwater throughout the San Joaquin Valley. ![]() Bureau of Reclamation in 1931 due to the Great Depression. ![]() The canal travels through six California counties: Alameda, San Joaquin, Stanislaus, Merced, and Fresno counties.Īfter years of drought, the state of California highlighted the importance of a large-scale water project, thus creating the California State Water Plan, but eventually being taken over by the U.S. The canal runs southward along the western edge of the San Joaquin Valley, parallel to the California Aqueduct, and diverges to the east after passing the San Luis Reservoir, receiving more water and eventually emptying into the San Joaquin River near the city of Mendota. Water is lifted 197 ft (60 m) from the Sacramento-San Joaquin Delta at the Clifton Court Forebay. Bill Jones Pumping Plant (formerly the Tracy Pumping Plant). It carries freshwater to replace San Joaquin River water which is diverted into the Madera Canal and Friant-Kern Canal at Friant Dam. Bureau of Reclamation as part of the Central Valley Project. The canal was designed and completed in 1951 by the U.S. The Delta–Mendota Canal is a 117-mile-long (188 km) aqueduct in central California, United States. Delta Mendota Canal, in blue, runs northwest to southeast, in the central part of the map.
