With the ever-changing climate and increasingly dry summers, California faces water challenges, despite this year’s bountiful snowpack. At the February meeting of the California Water Commission, Heather Cooley, Director of Research at the Pacific Institute, explained how increasing water efficiency, water reuse, and stormwater capture is essential to building and enhancing California’s water resilience.
Soggy, snow-capped California faces the likelihood of yet another month of wet weather, but what remains uncertain is whether this late winter precipitation will augment weeks of record-setting snowpack, or cause it to vanish should warmer rains arrive.
Last week, a frigid storm transformed portions of the state into a white landscape while toppling trees, prompting power outages, spurring water rescues and leaving some residents trapped by heavy snow.
California Gov. Gavin Newsom signed an executive order on Monday to safeguard his state’s water supplies from the effects of extreme weather.
The order will help expand California’s capacity to capture storm runoff during wet years by accelerating groundwater recharge projects, according to the governor’s office.
When it comes to the view of desalination as a tool to drought-proof local water systems in California, 2022 has been a roller-coaster year. In May, the California Coastal Commission, a 12-member appointed board responsible for overseeing the state’s 1,100 miles of coastline, rejected on environmental grounds a $1.4 billion desalination facility proposed for Huntington Beach.
The Sierra snowpack vital to supplying water for California’s residents, businesses, and farms is off to a strong start. Recent storms bringing rain to the Valley and other parts of the state are also dumping snow on the Sierra Nevada. According to the state Department of Water Resources, the northern Sierra snowpack is 155% of normal through Monday. Meanwhile, the central Sierra and southern Sierra snowpacks are 166% and 216% of normal, respectively.
The winter storm that dropped rain across the Bay Area dumped snow on the Sierras and ski resorts across Tahoe. Heavy snow and slick roads also made for dangerous driving conditions but the precipitation is a boon for California’s water supply. Building on gains during a storm in early November, this latest storm brought statewide snowpack up to 106% of normal for December 1, according to the California Department of Water Resources.
For at least a decade, off and on, state water managers and local water agencies have pursued the holy grail of a master agreement to improve the environmental health of the Sacramento-San Joaquin Delta by increasing its water flows.
With California butting up against 840 miles of ocean, desalination seems an obvious solution to the state’s water woes. However, the cost, energy demands and environmental impacts have made the technology largely unworkable. Three years of drought may be changing the calculus.
Balancing the state’s groundwater supplies for a sustainable future may not be easy due to severe drought and ongoing economic challenges facing farmers. “We’ve got the lowest prices and highest production costs and the least-reliable water supply that we’ve had since I’ve been farming,” said Bill Diedrich of Firebaugh, who farms row crops and permanent crops on the west side in Madera and Fresno counties. “We’ve had one or the other but not all three at the same time.”
The third attempt could be the charm for repairing California’s main waterworks, the Sacramento-San Joaquin River Delta.
On paper at least, the latest plan by a governor to upgrade the delta into a more reliable state water supply seems to make much more sense than what his predecessors promoted.
Gov. Gavin Newsom’s single-tunnel proposal is smaller and more respectful of the bucolic estuary’s small farms, waterfowl habitat, unique recreational boating and historic tiny communities. So, it’s potentially less controversial.
