The aqueduct begins at the
San Joaquin-Sacramento River Delta at the
Banks Pumping Plant, which pumps from the
Clifton Court Forebay. Water is pumped by the Banks Pumping Plant to the
Bethany Reservoir. The reservoir serves as a forebay for the
South Bay Aqueduct via the
South Bay Pumping Plant. From the Bethany Reservoir, the aqueduct flows by gravity approximately 60 mi (97 km) to the
O'Neill Forebay at the
San Luis Reservoir. From the O'Neill Forebay, it flows approximately 16 mi (26 km) to the
Dos Amigos Pumping Plant. After Dos Amigos, the aqueduct flows about 95 mi (153 km) to where the
Coastal Branch splits from the "main line". The split is approximately 16 mi (26 km) south-southeast of
Kettleman City. After the coastal branch, the line continues by gravity another 66 mi (106 km) to the Buena Vista Pumping Plant. From the Buena Vista, it flows approximately 27 mi (43 km) to the Teerink Pumping Plant. After Teerink it flows about 2.5 mi (4.0 km) to the Chrisman Pumping Plant. Chrisman is the last pumping plant before
Edmonston Pumping Plant, which is 13 mi (21 km) from Chrisman. South of the plant the west branch splits off in a southwesterly direction to serve the
Los Angeles Basin. At Edmonston Pumping Plant it is pumped 1,926 ft (587 m) over the
Tehachapi Mountains.
