El Niño is likely next winter and that could play an important role in the weather in parts of storm-weary California and the West.
But there are some important caveats and stubborn myths about this that also need to be addressed.
Water levels fell so low in key reservoirs during the depth of California’s drought that boat docks sat on dry, cracked land and cars drove into the center of what should have been Folsom Lake.
Those scenes are no more after a series of powerful storms dumped record amounts of rain and snow across California, replenishing reservoirs and bringing an end — mostly — to the state’s three-year drought.
The Bureau of Reclamation March 28, announced an increase in Central Valley Project 2023 water supply allocations. After below average precipitation in February, Reclamation announced a conservative initial water supply allocation for the CVP on Feb. 22. Additional atmospheric river systems have since boosted hydrological conditions and storage volumes, allowing for a more robust water supply allocation.
Since making initial allocations last month, Shasta Reservoir, the cornerstone of the Central Valley Project, has increased from 59% to 81%, and San Luis Reservoir, the largest reservoir south-of-Delta, from 64% to 97%. Record-breaking snowpack conditions currently exist in the Southern Sierra coupled with significant snowpack in the Central Sierra and Northern Sierra/Trinity.
Based on current hydrology and forecasting, Reclamation is announcing the following increases to CVP water supply allocations:
North-of-Delta Contractors
South-of-Delta Contractors
Friant Division Contractors
Friant Dam is currently being operated for flood control purposes; as long as these conditions exist contractors are able to take delivery of all available water from Friant Dam to the maximum extent of their respective contracts.
All other CVP water supply allocations remain the same as noted in the Feb. 22 announcement.
As the water year progresses, changes in hydrology, actions that impact operations, and opportunities to deliver additional water will influence future allocations. Reclamation will continue to monitor hydrology and may adjust basin-specific allocations if conditions warrant an update. Water supply updates and past year’s allocations are posted on Reclamation California-Great Basin Region’s website.
California Gov. Gavin Newsom ended some of the state’s water restrictions on Friday because a winter of relentless rain and snow has replenished the state’s reservoirs and eased fears of a shortage after three years of severe drought.
He also announced local agencies that supply water to 27 million people and many farmers would get much more from state supplies than originally planned. But Newsom did not declare an end to the drought, warning much of the state is still suffering from its lingering effects.
“Are we out of a drought? Mostly — but not completely,” Newsom said Friday from a farm northwest of Sacramento that has flooded its fields to help replenish groundwater.
Newsom said he would stop asking people to voluntarily cut their water use by 15%, a request he first made nearly two years ago while standing at the edge of a nearly dry Lopez Lake in the state’s Central Coast region — a lake that today is so full from recent storms it is almost spilling over. Californians never met Newsom’s call for that level of conservation — as of January the cumulative savings were just 6.2%.
Gov. Gavin Newsom on Friday relaxed drought rules in California amid a winter season filled with atmospheric river storms, flooding and a massive Sierra Nevada snowpack — soaking conditions that followed three dry, grueling years that had been marked by water shortages, extreme wildfires and heat waves.
The snow water equivalent of California’s snowpack is 190% of average for March 3, 2023. After three years of drought, the bountiful winter is good news, but a drier future demands more conservation and innovative solutions for water supply in the Southwestern U.S.
Now that the shock of a series of January storms has worn off, Los Angeles County officials face a herculean chore: Five reservoirs along south-facing San Gabriel Mountain slopes are filled with so much debris and soupy mud that they pose a flood risk to the communities below.
Flowers are blooming in the desert. Flooding and sewage spills have largely receded. Dams continue to collect runoff. But the drought is still far from over.
San Diego recently weathered a monthlong series of storms that also blanketed much of the West with badly needed snow. Still, the possibility of state-mandated water restrictions looms over the region this year, especially if dry conditions return to the Sierra Nevada.
Residents and local officials in San Diego are now taking stock of the situation as the deluges appear to be giving way to sunnier skies. While urban areas are still riddled with potholes and beach closures, rains have revived parched natural landscapes.
Early January was an unusually wild ride of atmospheric rivers. Nine sizable systems produced a train of storms beginning about New Years and lasting for several weeks across almost all of California. After three years of drought, the storms reminded us that California has flood problems similar in magnitude to its drought problems, and that floods and droughts can occur in synchrony.
After the driest three years in the state’s modern history, California suddenly has a different problem on its hands: too much water.
An ongoing series of storms drenching the state has forced officials to take measures unfathomable just a month ago, like releasing excess water from reservoirs and pumping surging river flows into storage.
