January storms propelled California from a state of water scarcity to one of water optimism.
The drought outlook in much of the state has improved thanks to continued and steady precipitation, and with more than two months left in the wet season, snowfall in the Central Sierra mountains of California has already reached 100% of the average for an entire year.
The failure of California and six other Western states to meet a Jan. 31 deadline for deciding how to divvy up the dwindling water supplied by the Colorado River clears the way for one of the biggest fights over natural resources in U.S. history — and already the Golden State is being cast as the villain in some national coverage for being the sole holdout to a deal agreed to by Arizona, Nevada, Colorado, Wyoming, New Mexico and Utah. Due to a regional “megadrought” now in its third decade and the accelerating climate emergency, the Biden administration last year called for creation of a plan that cuts annual water use by at least 15 percent.
When devastating floods swept California last month, the community of Grayson – a town of 1,300 people tucked between almond orchards and dairy farms where the San Joaquin and Tuolumne rivers converge – survived without major damage.
In the minds of some townspeople and experts, that was thanks partly to the 2,100 acres (850 hectares) of former farmland just across the San Joaquin that have been largely restored to a natural floodplain.
Snowpack has been running well above average this winter across the Colorado River watershed. It’s a rare bright spot after 23 years of grinding megadrought brought the driest conditions in 1,200 years to the basin that supplies 40 million people in Arizona, California, Colorado, Nevada, New Mexico, Utah, Wyoming, and Mexico.
Should the generous rains and mountain snows continue into spring, they could help head off a deeper water crisis, including perhaps an unprecedented loss of hydropower generation from severely depleted Lake Powell and Lake Mead.
After a key deadline passed this week without an agreement on how to address the Colorado River’s crisis, California is now sharply at odds with six other states over how to take less water from the shrinking river.
Now that California has rejected a plan offered by the rest of the region, the state has entered a political tug-of-war with high stakes. So why has the state that uses the most Colorado River water decided to go it alone?
The atmospheric rivers that pummeled California are a far cry from what a series of extreme storms could potentially bring, climate scientist Daniel Swain said at a legislative hearing on Wednesday that explored the impacts of the recent storm sequence.
“We’re nowhere near the kinds of events that we think are possible in a warming climate,” said Swain, a researcher at UCLA and The Nature Conservancy.
California may celebrate having double the expected snowpack after a string of atmospheric river storms, but state water experts warn that more needs to come to offset years of record-breaking drought.
At the season’s second monthly snowpack survey conducted Wednesday at Phillips Station — at the intersection of Highway 50 and Sierra-at-Tahoe Road — the California Department of Water Resources measured current snow depths and water content.
If you thought San Diego County was off to a particularly wet start to the new year, you’re absolutely right. The National Weather Service said with January, the region experienced its wettest month since February 2005.
Winter storms brought measurable rain to the county last month, bringing a rain total of 5.14 inches, according to the agency. The average January rainfall in San Diego is 1.98 inches, to give you a better idea of how wet conditions have been.
The mountain snowpack that supplies a significant amount of California’s water got an incredible boost from recent powerful storms and is outpacing the state’s wettest season on record, state water officials said Wednesday.
But its too soon to know if the winter will be a drought-buster, they said.
The Department of Water Resources said Wednesday the snowpack in the Sierra Nevada has reached 205% of normal thanks to a series of storms, though dry weather between now and April could still threaten water supplies.
The snowpack received a significant boost from one of the wettest three-week periods on record in California, following the driest three-year period on record.
