Water Districts Gain Access to New Supply

Millions of Southern Californians who were required to dramatically reduce their water use last year will have increased access to water in the future under two projects recently announced by the Metropolitan Water District.

Metropolitan—the nation’s largest water wholesaler and sole water provider to the local Las Virgenes and Calleguas municipal water districts—approved a $9.8-million contract for the Sepulveda Feeder Pump Stations Project that will bring additional water from the Colorado River, as well as water stored at Diamond Valley Lake in Riverside County, to the two local districts.

‘Nature Gave Us a Lifeline’: Southern California Refills Largest Reservoir After Wet Winter

Following a series of winter storms that eased drought conditions across the state, Southern Californians celebrated a sight nobody has seen for several punishing years: water rushing into Diamond Valley Lake.

The massive reservoir — the largest in Southern California — was considerably drained during the state’s driest three years on record, with nearly half of the lake’s supply used to bolster minuscule allocations from state water providers.

Here’s How Low California’s Reservoirs Are and What to Expect in the Future

Here’s a look at the status of California’s reservoirs during another drought:

There has not been much good news about California’s water supply lately, but there could be some relief on the way. The North-of-Delta Offstream Storage project, often referred to as the planned Sites Reservoir, was authorized by Congress in 2003. The long delayed project got a financial boost in March when the federal government signaled its intent to loan the project nearly $2.2 billion — about half of the cost to design, plan and build it.

Diamond Valley Lake Acts as Water Safety Net for SoCal

An area in Hemet offers a spot for people to get a little relief from triple-digit heat by cruising in their boats around a giant body of water.

However, Diamond Valley Lake also plays an important role when it comes to Southern California’s water supply. It is especially vital because Gov. Gavin Newsom has asked Californians to cut their water usage by 15% as the state drought continues to intensify.

This Giant ‘Inland Ocean’ is Southern California’s Last Defense Against Drought

Mechanical engineer Brent Yamasaki set out amid the recent blistering heat wave to take stock of the giant dams, pumps and pipes that support Diamond Valley Lake in Riverside County, the largest storehouse of water in Southern California.

The reservoir, which he helped build 25 years ago, is 4½ miles long and 2 miles wide and holds back nearly 800,000 acre-feet of water — so much that it would take 20,000 years to fill it with a garden hose.

SoCal Sees Turnaround in Water Supply as Reservoirs Reach Historic Levels After Years of Drought

Just five years ago, the boat launch at Diamond Valley Lake barely met the water’s edge. Today, the same area is under water thanks to recent rain and snow.

It’s a turnaround that has the Metropolitan Water District of Southern California cautiously optimistic.
