Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.


Federal pumping plant (5204377363).jpg

The C.W. Bill Jones Pumping Plant (formerly the Tracy Pumping Plant) [1] located 9 miles northwest of Tracy, CA, was constructed between 1947 and 1951, and is a key component of the Central Valley Project. [2] The Delta Cross Channel intercepts Sacramento River water as it travels westwards towards Suisun Bay and diverts it south through a series of man-made channels, the Mokelumne River, and other natural sloughs, marshes and distributaries. From there, the water travels to the C.W. Bill Jones Pumping Plant, which raises water into the Delta-Mendota Canal, which in turn travels 117 miles (188 km) southwards to Mendota Pool on the San Joaquin River, supplying water to other CVP reservoirs about midway. The Tracy Fish Collection Facility exists at the entrance of the pump plant in order to catch fish that would otherwise end up in the Delta-Mendota Canal. [3]

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

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.

Delta Cross Channel

The Delta Cross Channel is a facility in California's Sacramento-San Joaquin Delta that diverts water from the Sacramento River. The facility was built in 1951 in Walnut Grove, California. It diverts water to Snodgrass Slough, from where it flows to the Mokelumne River, then to the San Joaquin River, towards the C.W. Bill Jones Pumping Plant, which is the intake for the Delta-Mendota Canal, part of the Central Valley Project. The distance from the channel to the Jones Pumping Plant is about 50 miles.

Suisun Bay bay on the California coast of the United States

Suisun Bay is a shallow tidal estuary in northern California. It lies at the confluence of the Sacramento and San Joaquin Rivers, forming the entrance to the Sacramento–San Joaquin River Delta, an inverted river delta. Suisun Marsh, the tidal marsh land to the north, is the largest marsh in California. Grizzly Bay forms a northern extension of Suisun Bay. The bay is directly north of Contra Costa County.

The Jones Pumping Plant provides water service to 32 water districts within the western San Joaquin Valley, San Benito and Santa Clara counties. Of the approximate 3,000,000 acre feet (3.7×109 m3) of water distributed, 2,500,000 acre feet (3.1×109 m3) is delivered to farms, 200,000 acre feet (250,000,000 m3) to urban areas, including Tracy and cities with in the Santa Clara Valley Water District, and 300,000 acre feet (370,000,000 m3) for wildlife refuges.

Sacramento–San Joaquin River Delta Inland river delta and estuary in Northern California

The Sacramento–San Joaquin River Delta, or California Delta, is an expansive inland river delta and estuary in Northern California. The Delta is formed at the western edge of the Central Valley by the confluence of the Sacramento and San Joaquin rivers and lies just east of where the rivers enter Suisun Bay. The Delta is recognized for protection by the California Bays and Estuaries Policy. Sacramento–San Joaquin Delta was designated a National Heritage Area on March 12, 2019. The city of Stockton is located on the San Joaquin River on the eastern edge of the delta. The total area of the Delta, including both land and water, is about 1,100 square miles (2,800 km2). Its population is around 500,000 residents.

San Luis Reservoir lake in Merced County, California, United States of America

The San Luis Reservoir is an artificial lake on San Luis Creek in the eastern slopes of the Diablo Range of Merced County, California, approximately 12 mi (19 km) west of Los Banos on State Route 152, which crosses Pacheco Pass and runs along its north shore. It is the fifth largest reservoir in California. The reservoir stores water taken from the San Joaquin-Sacramento River Delta. Water is pumped uphill into the reservoir from the O'Neill Forebay which is fed by the California Aqueduct and is released back into the forebay to continue downstream along the aqueduct as needed for farm irrigation and other uses. Depending on water levels, the reservoir is approximately nine miles long from north to south at its longest point, and five miles (8 km) wide. At the eastern end of the reservoir is the San Luis Dam, or the B.F. Sisk Dam, the fourth largest embankment dam in the United States, which allows for a total capacity of 2,041,000 acre feet (2,518,000 dam3).

The Peripheral Canal was a series of proposals starting in the 1940s to divert water from California's Sacramento River, around the periphery of the San Joaquin-Sacramento River Delta, to uses farther south. The canal would have attempted to resolve a problem with the quality of water pumped south. Pumps create such a powerful suction that the boundary between freshwater to saltwater has shifted inland, negatively affecting the environment. The pumps have increased by 5 to 7 million acre feet the amount of water exported each year to the Central Valley and Southern California. However, the peripheral canal as proposed would have reduced the overall freshwater flow into the Delta and move the freshwater-saltwater interface further inland, causing damage to Delta agriculture and ecosystems.
