Alarm Bells As Drought Worsens and Californians Come Up Short On Water Conservation
Californians reduced their water use at home by a meager 1.8% statewide in July compared to last year, even after Gov. Gavin NewsomÂ urged residents to conserve 15%Â and drought continues to spread across the state.
Officials today warned water providers south of the Delta who rely on state water allocations â alreadyÂ slashed to 5% this yearÂ â to brace for the possibility of zero supply next year.
The Department of Water Resources also cautioned that next yearâs cuts in supply could expand to growers and others known asÂ settlement contractors, whose claims to the water predate Californiaâs massive systems of reservoirs, aqueducts and canals.
âCalifornians always have hope, and thatâs healthy. But we need to be prudent,âÂ Karla Nemeth, director of the state Department of Water Resources, said in an interview. âWeâre doing more conservative planning than weâve ever done.â
Drought conditions deemed extreme or worse now coverÂ nearly 90% of the state.Â HundredsÂ ofÂ domestic wells are running dry, and levels in major reservoirs haveÂ dropped drasticallyÂ below historic averages â which bodes ill for supplies next year.
âThe challenge is there is no water,â Nemeth said.
âWeâre planning for the worst, but we are hoping for something better,â Nemeth added at todayâs meeting of the State Water Resources Control Board.
Whoâs conserving and whoâs not?
In early July, Newsom urged Californians to voluntarilyÂ cut domestic water useÂ by 15%, but in the absence of a statewide mandate,Â a patchwork of restrictionsÂ has emerged. The result: Californians used about 191.5 billion acre feet of water in their homes, businesses and other industrial or institutional spaces in July, only 1.8% less than a year earlier.
âIâm not here to say 1.8 is a good number,â saidÂ Joaquin Esquivel, chair of the State Water Resources Control Board, at a Monday press briefing. âWeâre going to have to continue to dig in deeper and look forward to seeing what the numbers show then in August.â
When asked when to expect statewide conservation orders, Esquivel said that for now, the board is reflecting on the data. âWe need to continue to see that response and decision-making, and the stateâs here to make sure that if we need to go mandatory, thatâs where weâre going.â
The biggest drops in household water use were alongÂ the hard-hit North Coast, with a nearly 17% reduction in July 2021 compared with July 2020. The Sonoma County city of Healdsburg led the state by cutting its water use by more than half, and Cloverdale, which reduced its use by 37%.Â BothÂ citiesÂ enacted mandatory water use restrictions.
Water use in the South Coast region, which includes Los Angeles, Orange, San Diego and Ventura counties, was roughly even with last summer, down 0.1%. However, about 40% of water suppliers in the area actually used more water.
The biggest increases came in El Segundo, up 31%; the Mission Viejo-Laguna Niguel area, up 15%; and the cities of Downey and Poway and Ventura Countyâs Casitas district, up 14%. The Los Angeles Department of Water and Power and the city of San Diego used about 1% more.
San Francisco Bay Area residents cut their water use by 8.4%. Northern and southern San Joaquin Valley residents reduced use by 0.8% and 1.6%, respectively.
The statewide calculation doesnât include two suppliers â the city of Exeter in Tulare County and the Desert Water Agency in the Coachella Valley â that had unexpectedly high water use. âTheir percent increase was higher than reasonable and my attempts to confirm both 2020 and 2021 numbers received no reply,â said water board data specialist Marielle Pinheiro.
A squeeze south of the Delta
Officials warned that major cuts could come for irrigation districts, cities and other water users south of the Delta relying on supplies fromÂ the State Water Project, which provides water to 27 million Californians and 750,000 acres of farmland.
At this point, Nemeth said thereâs âa slim likelihoodâ of supplies for these water systems, which includes the giant Metropolitan Water District, which provides imported water to 19 million people in Southern California. Worst-case scenario, she said, âweâve asked them to plan for no allocation from the State Water Project.â
Those suppliers,Â including inÂ the Bay Area, Southern California, the Central Coast and the San Joaquin Valley, have seen steep cuts before,Â during the last drought in 2014. But this time is worse: Even a wet year is unlikely to bring relief.
âWeâre starting with record low (reservoir) storage,â Nemeth said. âWe would have to have north of 140% of (average) precipitation to generate average runoff into the reservoirs that would begin filling that hole.â
Jennifer Pierre, general manager of the State Water Contractors, an association of public water agencies, said âa 0% allocation next year would be extremely challenging.â
Even landowners, irrigation districts and others with rights to water that predate state and federal water projects could see their water supplies squeezed next year, Nemeth said. These water users agreed in contracts decades ago to limit their water rights to allow construction of the massive projects, which transferred water south. Their allocations arenât cut to the same extent as more junior contractors, such as the Metropolitan Water District.
âWith hydrology this bad, everythingâs on the table that we could cut them even deeper â even deeper than their contracts allow for,â Nemeth said. âI donât think we get out of next year without a lawsuit.â
State and federal project operators have come under fireÂ from environmental advocatesÂ for supplyingÂ hundreds of thousands of acre feetÂ to these senior contractors, whileÂ failing to meet water qualityÂ andÂ temperature standardsÂ and cutting allocations to more-juniorÂ agricultural contractorsÂ andÂ cities.
Feather River Contractors, for instance, were allocated the lowest levels allowed in their contracts, but still were expected to receive nearly 600,000 acre feet of water, accordingÂ to the Department of Water ResourcesÂ â enough water toÂ supply 1.8 million Southern California householdsÂ for a year. Thatâs about three times more water than long-term State Water Project contractors, including the giant Metropolitan Water District, were provided.
ForÂ endangered Sacramento River winter-run Chinook salmon, âweâve modeled the temperature dependent mortality at about 80% this year, meaning only 20% even survive to make it out of the gravel,âÂ Barry Thom, West Coast regional administrator for NOAA Fisheries, told the water board.
Doug Obegi, a senior attorney with the Natural Resources Defense Council, urged the board on Tuesday to require state and federal water project operators to cut supplies to settlement contractors to protect fish.
If supplies arenât reduced, âyouâre going to have even worse temperature mortality of salmon next year,â Obegi told CalMatters. âYou start with less water, and you have less at the end of the year, youâre going to have a lot more dead fish. Itâs grim.â
Nemeth said she issued the early warning to prepare growers dependent on senior contracts well in advance of making planting decisions.
Last year, early planting by growers âreally limited the amount of decisions we thought we could make without causing real economic damage,â Nemeth said. This year, âWe want to alert them sooner that it could be worse than theyâve experienced before.â
