The parade of atmospheric rivers that pounded California for three weeks finally faded on Monday, enabling the state to begin lengthy repairs to roads and levees as the White House announced President Biden planned to survey the damage.
Despite several weeks of torrential rain and flooding, California is still facing a severe multi-year drought. That has many people thinking about how to better capture winter floodwaters to last through the dry season.
An innovative approach at two California reservoirs could help boost the state’s water supply, potentially marking a larger shift from decades-old water management approaches to a system that can quickly adapt to precipitation in a changing climate.
It’s been a wild couple of weeks of weather in Northern California. But there is a rather bright silver lining to this train of storms: our surface water supply is getting a big boost.
Even with a sixth atmospheric river in two weeks dumping rain on California, water regulators said reservoirs are not likely to completely refill this year. As of Sunday, the state’s 17 reservoirs were at 78% of average, the Department of Water Resources announced Monday.
“We’re still below average,” said Jon Yarbrough, assistant deputy director for the State Water Project, the California agency that collects water from Northern California rivers and redistributes it to major cities. “We still have a lot of room in our reservoirs to take in the in-flows that we’re seeing on the horizon here.”
While many areas of California are coping with the destructive impact of relentless rainfall, the news is nothing but good when it comes to the state’s snowpack. As of Monday, California’s snow water equivalent was 199% of normal for the date (January 9), according to the California Department of Water Resources.
Lake Mead will need more than just rainfall to replenish itself, an expert has told Newsweek.
Spread between Nevada and Arizona—Lake Mead, the largest man-made reservoir in the U.S.—is best known for its rapidly declining water levels due to the ongoing megadrought gripping the western states. The lake is integral to surrounding communities, as it is also formed by the Hoover Dam on the Colorado River—which generates electricity for thousands of people. If the water levels continue to decline, the consequences could be catastrophic.
As climate change continues to shrink the Colorado River’s largest reservoirs, a group of four states that use its water are set to lay out plans to reboot a conservation program. The Upper Colorado River Commission – comprised of Colorado, Utah, Wyoming and New Mexico – plans to announce details of an extended “System Conservation Pilot Program” through which water users could be paid to cut back on their use.
The soon-to-be-launched program aims to use a pool of $125 million from the Inflation Reduction Act for payouts to “mitigate the impacts of long-term drought and depleted storage,” according to presentation slides obtained by KUNC.
Chula Vista, Calif. – In order to secure additional water sources for our customers, Sweetwater Authority initiated a controlled transfer of water between its two reservoirs on November 15, 2022. Water that leaves Loveland Reservoir is transferred through the Sweetwater River channel and captured at Sweetwater Reservoir where it can be treated and distributed to Authority customers at a lower cost than importing water. Drought conditions and lack of rainfall in the region have created a need to transfer this water to Sweetwater Reservoir.
The Marin Water District has a new plan to deal with California’s worsening drought.
As of Oct. 24, Marin reservoirs have more water than normal, but the county said they’re not waiting for things to get worse.
Marin’s seven reservoirs hold 80,000 acre feet of water, the new plan would kick in when levels fall below 70,000 acre feet. The prior conservation plan didn’t go into effect until levels fell to 50,000.
While many environmentalists oppose the construction and expansion of dams, the Biden Administration believes in the value of above-ground water storage.
The Department of Interior on Monday announced $210 million in funding for water storage and conveyance projects in the western United States.
