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.
In Cantua, a small town deep within California’s farming heartland, the heat had always been a part of life. “We can do nothing against it,” said Julia Mendoza, who’s lived in this town for 27 years. But lately, she says, the searing temperatures are almost unlivable.
By midday on Thursday, the first day of a protracted, extreme heatwave in California’s Central Valley, the country roads were sizzling with heat. A young volunteer with a local environmental justice non-profit who had come to check in on the neighborhood collapsed on the sidewalk, her face bright red and damp. Construction crews working nearby quickly swept her into an air-conditioned car and handed her a cold bottle of water.
Lawmakers in Congress on Friday introduced a bill that would pump tens of billions of dollars into fixing and upgrading the country’s dams.
The Twenty-First Century Dams Act, introduced by Democratic U.S. Rep. Annie Kuster of New Hampshire, proposes to spend nearly $26 billion to make the repairs that would enhance safety and increase the power generation capacity of the country’s 90,000 dams. It also calls for removing any dams that have outlived their usefulness.
The drought-tolerant landscaping at Christine Laframboise’s El Cajon home has been a work in progress since 2015, when she, her husband and their son painstakingly pulled out two layers of grass and sod — 1,070 square feet of lawn.
This past week, her front garden took top honors in the Otay Water District’s WaterSmart Landscape Contest.
The annual contest is held by many water agencies in San Diego County to encourage and recognize residents who exemplify outdoor water-use efficiency. Agencies judge lawns in their service areas, looking at “before” and “after” photos from entrants, then awarding top picks.
A California water myth which becomes especially pernicious in droughts is that California is “running out of water” (Hanak et al. 2009). Viewing California’s supply and demand pressures in terms of fixed water requirements perpetuates this myth and invariably places undue attention on building additional supply infrastructure. Instead, managing water as a scarce resource suggests a balanced portfolio of water trading, investments in conveyance, smart groundwater replenishment, and demand management. With such a balanced portfolio, 1) California’s water supply situation is not broadly dire, and 2) California’s vast and interconnected water infrastructure and groundwater resources can minimize most problems from the state’s highly variable climate.
In the face of rapidly worsening drought conditions this week, Gov. Gavin Newsom urged all Californians to voluntarily cut their water usage by 15% — but what exactly does that mean for the average California household?
The governor made his plea Thursday as he extended a regional state of drought emergency to 50 counties, comprising about 42% of the state’s population. For many, the talk of water reductions reminded them of the shriveled lawns, attenuated showers and water-bucket toilet flushing of the last devastating drought.
It also prompted some to wonder just how much more water Californians can conserve, since they continue to use substantially less water than they did before the 2012-2016 drought.
Although Southern California is not included in the state’s drought-emergency proclamation, Gov. Gavin Newsom Thursday urged residents across the state to voluntarily cut their water use by 15% amid worsening conditions across the West Coast.
He also called on businesses to slash their water use. According to the governor’s office, a 15% cut in water use would save 850,000 acre-feet of water — enough to supply more than 1.7 million households for a year.
Newsom said residents have responded to drought conditions before, and he was confident they would take steps again to ease their water use.
California Gov. Gavin Newsom asked people and businesses Thursday to voluntarily cut how much water they use by 15% amid a drought. Newsom’s request is not an order. But it demonstrates the growing challenges of a drought that will only worsen throughout the summer and fall and is tied to recent heat waves.
Sandra L. Kerl, general manager of the San Diego County Water Authority, issued the following statement following the governor’s announcement:
“While the San Diego region is thankfully drought-safe this summer due to sound planning and decades-long ratepayer investments in new water supplies and storage and adoption of water conservation as a way of life, we must also be part of the statewide movement now underway to address water supply challenges created by drought and climate change in other parts of California.
“The Water Authority strongly supports the governor’s call for the public to voluntarily cutback water use by 15% in order to allow local, regional and state water agencies to plan and take the steps necessary under these changed conditions to maximize the availability of limited water supplies going forward, through the investment of state funding and implementation of other provisions of the Governor’s Proclamation of a State Emergency and Executive Order N-10-21 calling for water conservation.
“The Water Authority will be working closely with our member agencies and with the Metropolitan Water District of Southern California over the next several days, weeks and months, to design and implement strategies to maximize water supply development in collaboration with Governor Newsom and state agencies, in order to protect California.”

The Colorado River is tapped out.
Another dry year has left the waterway that supplies 40 million people in the Southwest parched. A prolonged 21-year warming and drying trend is pushing the nation’s two largest reservoirs to record lows. For the first time this summer, the federal government will declare a shortage.
Climate change is exacerbating the current drought. Warming temperatures are upending how the water cycle functions in the Southwest. The 1,450-mile long river acts as a drinking water supply, a hydroelectric power generator, and an irrigator of crop fields across seven Western states and two in Mexico. Scientists say the only way forward is to rein in demands on the river’s water to match its decline.
The possible return of La Niña threatens to give the drought-ravaged U.S. West another winter without much rain or snow.
The U.S. Climate Prediction Center issued a watch for La Niña on Thursday, saying there’s a 66% chance the phenomenon will return for a second straight year some time in the November-January period. La Niña occurs when the equatorial Pacific Ocean cools, triggering an atmospheric chain reaction that can cause droughts across the western U.S. and roil weather systems globally.
