Surplus of water has filled many of the state’s depleted reservoirs
Central California’s San Luis is at 98% full after being at quarter capacity in December.
California’s reservoirs have been in the spotlight after months of precipitation and the end of the drought in much of the state.
A surplus of water has filled several major reservoirs, which had seen perilously low levels.
Among them is the San Luis Reservoir, which sat at just one-quarter of its capacity on Dec. 1. The basin is now 98% full.
The reservoir, California’s fifth-largest, is near Los Banos in Merced County and supplies water to the State Water Project.
After a stunning turnaround, it sits at 114% of its historical average level.
In spring 2022, the reservoir’s water level was well under half of capacity. Over the summer, warmer weather dried out the landscape.
The reservoir continued to lose water through the fall, ultimately settling at around 25% of capacity through November and December.
A year earlier, before meager winter rains, the San Luis Reservoir had dropped to a staggering 10% of capacity in November 2021.
But this year has been a different story.
Atmospheric rivers have delivered incredible amounts of rain and snow, bringing record snowpack in the Sierra Nevada, the resurrection of Lake Oroville and dangerous flooding across the state.
Most of the state’s reservoirs are now at or above their historical average levels.
As of March 28, state reservoirs stood at about 73% capacity, above the 30-year average of 69% for the month of March.
All the water came from a remarkable winter of storms.
It resulted in perhaps the deepest snowpack recorded in more than 70 years, officials said Monday.
The snowpack is so deep that it currently contains roughly 30 million acre-feet of water — or more water than Lake Mead, the nation’s largest reservoir, according to a Times analysis of snow sensor data.
