In California, the snowpack is at some of the highest levels in recorded history.
The state’s snowpack accumulates in the Sierra Nevada—a mountain range that stretches for 400 miles from Northern California southward to the Great Basin. The snowpack, which melts into the state’s reservoirs, provides about a third of California’s total water supply.
Following a series of winter storms that eased drought conditions across the state, Southern Californians celebrated a sight nobody has seen for several punishing years: water rushing into Diamond Valley Lake.
The massive reservoir — the largest in Southern California — was considerably drained during the state’s driest three years on record, with nearly half of the lake’s supply used to bolster minuscule allocations from state water providers.
Camp Pendleton leaders on Monday sent a public notice to thousands of service members and civilians who live and work on the base’s north end alerting them that recent testing revealed their drinking water contained a higher-than-desired level of PFAS, a potentially carcinogenic chemical that has been found in much of Southern California’s groundwater supply.
PFAS, or per- and polyfluorinated substances, can be found in cleaning products, water-resistant fabrics, grease-resistant paper and non-stick cookware, as well as in products such as shampoo, dental floss and nail polish.
As the rain year continues to look promising, rice farmers are happy to expect most if not all of their water allocations will be delivered.
This week the Department of Water Resources announced a 75% water allocation to the irrigation districts served by the State Water Project.
The U.S. Environmental Protection Agency has awarded a $170 million low-interest loan to reduce financing costs for environmental upgrades that enhance the Claude “Bud” Lewis Carlsbad Desalination Plant. U.S. Rep. Mike Levin, who represents coastal communities including Carlsbad, helped secure the funds that will save ratepayers up to $54 million compared to alternate financing strategies.
“As we continue to confront increasingly frequent and intense droughts, today’s announcement is an exciting step in our efforts to provide sustainable, reliable water supplies for San Diego County,” said Rep. Mike Levin. “This low-interest federal loan will not only allow the Carlsbad Desalination Plant to improve its efficiency and environmental practices but will also save local water ratepayers tens of millions of dollars. I will never stop fighting to improve our region’s water security at the most affordable price for ratepayers.”
Floods and droughts are not opposites and can occur simultaneously. This occurs often in California and is especially well-illustrated this year.
Floods, droughts, and water scarcity are different. Floods are too much water at a place and time, and we would often pay to reduce the water present at that location and moment. Droughts and water scarcity represent too little water at a place and time, meaning we would often pay to increase its availability. We highlight these differences because people tend to view such conditions through an unrealistic zero-sum lens. This essay uses this year’s experience to examine how floods, drought, and water scarcity differ, can occur in the same year, and how droughts might end, but leave legacies.
This California drought is largely over. Even though there is another month left in California’s wet season, the 2020-2022 California drought is largely over. Precipitation in all major basins of California exceeds averages for the entire water year. Snowpacks are well above April 1 averages (usually about the maximum for the year). Most reservoirs have more than average volumes stored for this time of year, and many are in flood operations. Only a few very large reservoirs (relative to their average inflows) remain below historical averages (such as Trinity at 50% and New Melones at 90% of their averages).
Gov. Gavin Newsom came close but couldn’t quite bring himself to say it: The drought’s over.
It’s disappointing when a governor won’t acknowledge what ordinary citizens already know because they can see things for themselves.
Another drought will emerge soon enough. It always does. That’s the California pattern — climate change or not.
Spring is arriving sooner and warming up faster than ever before, new research shows. And that means more than just early wildflower blooms across Arizona.
A longer, warmer spring can stress water supplies in the West. The longer spring season may also produce ripple effects on agriculture as water demand will likely increase, and growing seasons may shift.
At an appearance at a groundwater recharge project in Yolo County, Newsom announced the end of state regulations he put in place last March that required cities and water agencies to impose water restrictions such as limits on the number of days a week residents could water lawns and landscaping. The decision now will be up to each local area in the coming weeks and months about whether to drop those restrictions.
After years of extreme drought and dismal snowpack, California has had a remarkably wet winter and is now veering into record-setting territory for snowfall.
As of Friday, the snowpack in the southern Sierra Nevada was at 286% of normal — the highest figure ever, easily eclipsing the region’s benchmark of 263% set in 1969.
