State Water Project
In a normal year California receives about 200 million acre-feet of water from precipitation (snow and rain fall) and imports from Colorado, Oregon and Mexico. One acre-foot is the amount of water it takes to cover a football field one foot deep.
In order to supply water to the growing populations of Southern California, engineers needed to develop adequate and reliable systems capable of moving water along the 700+ mile journey from Northern to Southern California. The system, formally known as the State Water Project includes:
- 33 Dams
- 34 Storage Facilities, Reservoirs and Lakes
- 25 Pumping and Hydro-Electric Generation Plants
- 701 Miles of Aqueducts
For the Santa Clarita Valley, the State Water Project water ends its journey in Castaic Lake where it is stored until it is used to provide clean drinking water.
