A Look at How Far Away Some of Southern California’s Water Needs to Travel

Southern California relies on most of its water coming from a long way away. Here’s a look at several of the aqueducts that keep our taps flowing year-round. California receives 75% of its rain and snow in the watersheds north of Sacramento. However, 80% of water demand comes from the southern two-thirds of the state.

About 25% of the water used in Southern California comes from the Colorado River. Another 30% originates in the northern Sierra. The remaining 45% comes from a mix of what are considered local supplies, which include Los Angeles’ Eastern Sierra deliveries as well as recycling, desalination and groundwater supplies.

Proposal to Place Solar Panels Over LA Aqueduct Advances

O’Farrell is the chair of the council’s Energy, Climate Change, Environmental Justice, and River committee.

Los Angeles May Store Water Under an Owens Valley Lake Drained to Fill its Faucets

The Los Angeles Department of Water and Power has launched studies of ambitious plans to store water in the lake’s underground aquifer so that it could be pumped up in summer months and drought years to create pools of water to limit the dust sweeping across the vast lakebed’s salt flats.
