California Water Project California has several major rivers, canals, and aqueducts.

Water facts!! Landscaping accounts for about half the water Californians use at home. Showers account for another 18%, while toilets use about 20%.

Water facts!! An acre-foot of water is about 326,000 gallons, or enough water to supply two typical families for a year. It takes 3.3 acre-feet of water to grow enough food for an average family for a year.

Water facts!! About 75% of California’s available water occurs north of Sacramento, while about 80% of the demand occurs in the southern two-thirds of the state.

Water Projects Two of the most important projects are the federal Central Valley Project (CVP) and the State Water Project (SWP).

Water Projects The CVP and SWP bring water from Northern California through the Sacramento-San Joaquin River Delta for delivery to users in the San Joaquin Valley, parts of the San Francisco Bay Area and Southern California

Where does the water come from? Local Water Projects Los Angeles Aqueduct Colorado River Aqueduct HetchHetchy Aqueduct Mokelumne Aqueduct

Where does the water come from? State Water Projects Feather River Basin California Aqueduct System of Canals Resevoirs Pumping Plants and Pipelines

Where does the water come from? Federal Water Projects All American Canal Coachella Canal Central Valley Project

History of the SWP Its main purpose is to store water and distribute it to 29 urban and agricultural water suppliers Of the contracted water supply, 70 percent goes to urban users and 30 percent goes to agricultural users.

History continued The Project includes: 32 storage facilities reservoirs and lakes 17 pumping plants 3 pumping-generating plants 5 hydroelectric power plants 660 miles of open canals and pipelines. The Project provides supplemental water to approximately 20 million Californians and about 660,000 acres of irrigated farmland.

Water Needs Agriculture- 80% of CA water 2/3 surface water 1/3 ground water

Water Needs Houses and Business- 50% Landscaping 38% Bathroom 12% Other

Water Needs Industry- Major use is cooling of equipment Manufacturing of beverages and paper Production of steam to generate electricity

Water Needs Recreation and Wildlife Rivers are the largest use Fisheries Wetlands
