How Water Gets From the Sierra Nevada Mountains to the Rest of California
•
Strong storms and cold temperatures are the right ingredients for a deep snowpack in the Sierra Nevada Mountains, which provides water for about 23 million Californians from the Bay Area to Southern California. So how does all that water actually travel hundreds of miles through the Bay Area and Central Valley to Southern California?

Before we get to the California Aqueduct, here's where California's water lifeline starts -- a snow-covered Sierra Nevada mountain peak. This view is to the northwest from the Phillips Station meadow where the California Department of Water Resources conducted its third snow survey of the winter 2017 season. Photo taken March 1, 2017.

Here's a look at conditions in the Sierra Nevada, Thursday, March 30, 2017, near Echo Summit, Calif. The location is where the California Department of Water Resources holds its manual snow survey at nearby Phillips Station. In late March 2017, the water content was at 183 percent of normal.

The snowpack is so important, California water resources managers keep a close eye on it.

When the mountain snow melts, it runs downhill in rivers and stream, eventually ending up in the State Water Project. This view is looking north from the California Aqueduct Vista Point, an exit off the southbound 5 Freeway near Exit 423/Stuhr Road in Stanislaus County west of the Sierra Nevada range. Photo taken March 4, 2013.

Separate from the California Aqueduct network is the the Los Angeles Aqueduct, built and maintained by the the LADWP. Unlike most of the water collected from the Sierras, the LA Aqueduct receives its water from runoff on the eastern side of the mountains. Here, it is seen with snowcapped Sierra Nevada Mountains in the background, carrying watter to major urban areas of southern California on May 9, 2008 near Lone Pine.
