Land and waterway managers labored hard over the course of a century to control California’s unruly rivers by building dams and levees to slow and contain their water. Now, farmers, environmentalists and agencies are undoing some of that work as part of an accelerating campaign to restore the state’s major floodplains.
The Biden administration took action Thursday to restore federal protections for hundreds of thousands of small streams, wetlands and other waterways, undoing a Trump-era rule that was considered one of that administration’s hallmark environmental rollbacks.
Californians are still lagging behind Gov. Gavin Newsom’s drought-emergency plea to use less water. Urban residents reduced water consumption by just 3.9% in September, compared with a year earlier, according to data released Tuesday by the State Water Resources Control Board. The August figure was a slightly better 5.1%.
Guidelines for how cities and local agencies should adapt roads, railways and water systems to accommodate rising seas were unanimously approved Wednesday by the state Coastal Commission.
The 230-page document sets a controversial benchmark by urging communities to prepare for the Pacific Ocean to rise 10 feet by 2100, a projection so far beyond current calculations that climate scientists haven’t yet determined the probability of it occurring.
With a severe drought and an increased reliance on groundwater basins, Calif.’s Department of Water Resources released the final version of its California’s Groundwater – Update 2020 report. The report, also known as Bulletin 118, contains critical information about the condition and use of the state’s groundwater, which is especially important as California faces the real-time impacts of climate change and drought.
“Groundwater plays a central role in sustaining our state’s ecosystems, businesses, agriculture and people, with some Californians relying solely on groundwater for drinking water,” said DWR Director Karla Nemeth. “The updated California’s Groundwater provides key information for the state and locals to better understand and manage groundwater as we adapt to variations in climate and navigate a historic drought.”
California is experiencing a devastating water crisis, by some accounts the worst in the last 1,200 years. Drought is hammering the two primary water delivery systems on which millions of Californians rely — the Colorado River and the Sierra Nevada Mountains.
Most of the state — and especially the south San Joaquin Valley and Kern County — is suffering badly. Extensive planning, and solid investments funded by large coffers, have enabled large portions of Southern California to get through 2021 without rationing. But the experience here in the Central Valley is far different. Thousands of acres fallowed. Jobs lost and hours cut. Multiple cities with water restrictions. Wells running dry. These disparate outcomes are highlighting the current inequalities in drought preparedness and a broken system. There is also the sobering reality that Southern Californians may too be thirsty again soon.
Water utilities are just the latest industry to experience high-profile cyber incidents.
Earlier this year, a hacker breached a California water treatment plant and removed programs used to clean water. In another incident that made national headlines, a hacker gained remote access to a Florida treatment plant and increased the amount of lye in the treatment process – a change that a plant employee fortunately noticed and quickly corrected.
Going back to a time when water utilities were less connected is not an option. COVID-19 demanded connected operations so employees could work remotely.
October storms helped this winter’s rainy season get off to a good start across Northern California. But they weren’t enough to erase the two very dry previous years: 80% of California remains in an extreme drought, according to the U.S. Drought Monitor, a weekly federal report.
Reservoir levels are very low and groundwater tables are depleted because the past two years had the least rainfall in Northern California of any two-year period since 1976-77.
Two and a half years after signing a deal aimed at averting a damaging crisis along the Colorado River, water officials from California, Arizona and Nevada are discussing plans to take even less water from the shrinking river and leave it in Lake Mead in an effort to prevent the reservoir from falling to dangerously low levels.
Representatives of water agencies from the three states said they are firming up the details of a deal that would leave an additional 500,000 acre-feet of water in the reservoir next year, and the same amount again in 2023 — about double the quantity of water used annually by Las Vegas and the rest of southern Nevada.
State water regulators urged Californians to do more to save water after the latest monthly data showed conservation lagging in September, with statewide water use in cities and towns decreasing 3.9% compared with the same month a year ago.
The reduction in water use was smaller than in August, when Californians used 5% less.
