Researchers from Colorado State University focused on areas they call “late snow zones” – regions in the Western mountains where snow doesn’t typically melt until May or later.
They found that between 1984 and 2020, wildfire activity increased in 70% of these zones throughout the West. The mountain ranges studied included the Sierra Nevada, Cascades, Basin and Range, and Northern and Southern Rockies.
California cities and farms should brace for little or no water from the state’s big reservoirs in the coming year, a prospect that signals more water restrictions for households and more fallowed fields in the farm belt.
The warning was delivered Monday by state and federal water officials who said they are preparing for the possibility of a fourth year of drought. Both are considering, at least initially, reduced allocations for the many water agencies that contract for reservoir supplies from California’s sprawling water projects.
In the spring of 1905, the Colorado River, bursting with seasonal rain, topped an irrigation canal and flooded the site of a dried lake bed in Southern California. The flooding, which continued for two years before engineers sealed up the busted channel, created an unexpected gem in the middle of the arid California landscape: the Salton Sea. In the decades that followed, vacationers, water skiers, and speed boat enthusiasts flocked to the body of water. The Beach Boys and the Marx Brothers docked their boats at the North Shore Beach and Yacht Club, which opened in 1959. At the time, it seemed like the Salton Sea, and the vibrant communities that had sprung up around it, would be there for centuries to come.
The day before the state’s “water year” ended, Silicon Valley leaders gathered on Google’s campus in Mountain View and urged residents to continue conserving water as California’s drought drags on.
“It’s the third straight year of a bad and worsening drought,” said Wade Crowfoot, secretary of the California Natural Resources Agency, on Thursday. “Our scientists and climatologists predict that as we move into the winter, we can expect another, fourth dry year.”
This summer, officials of the U.S. Interior Department gave seven states in the American West an ultimatum – either come up with a voluntary agreement to curtail their use of water from the Colorado River, or the federal government will impose mandatory restrictions. Lake Mead, the reservoir created by the Hoover Dam on the Colorado, is now at just 25% of its capacity.
Nearing the end of the water year on Sept. 30, California farmers and water officials are eager to turn the page to begin the next opportunity for the state to accrue snowpack and precipitation.
However, with a La Niña atmospheric phenomenon in the Pacific Ocean, which generally signals drier, warmer conditions, water officials say they are preparing for a fourth dry year next year.
Downtown-based water infrastructure company Cadiz Inc. last month encountered yet another legal setback in its 25-year effort to convey water from its desert aquifer to a regional water aqueduct when a federal judge revoked a permit to use an old natural gas pipeline.
But far from putting its project on hold, Cadiz in subsequent days announced it would begin digging three new wells atop its aquifer and that it had completed an engineering study on converting the natural gas pipeline to carry water.
Governor Gavin Newsom signed a new law on Wednesday to make it cheaper for Californians to replace their traditional grass lawns with more sustainable, drought-resistant plants. The focus behind this new law is to help Californians save water, and a big way they can do that is by opting for these more sustainable plants and landscaping.
With California’s water supply shrinking and the drought dragging on, Bay Area water agencies are getting serious about persuading their customers to use water responsibly.
NASA satellite photos show how drastically the water levels in Lake Powell and Lake Mead have receded in just the past few years. They demonstrate the severity of long-term drought and the challenges Arizona will face to conserve and enhance its precious water supply.
