For a second consecutive yr, Californians can have a good time the rejuvenation of the state’s reservoirs.
Lake Shasta, the state’s largest reservoir, is full once more after reaching perilously low ranges within the drought-stricken years from 2019 via 2022.
The satellite tv for pc photographs beneath, from the NASA, present the lake in April 2022, at left — when it was at 40% capability — after which a bit of over two weeks in the past, when the lake was a lavish 96% full.
On Could 7, the lake was at 114% of its historic common stage. The so-called bathtub ring that clearly outlined the lake in 2022 — so stark it was seen from area — had disappeared by 2024.

On that day, the lake’s bathtub ring was gone, with water overlaying the helps on the Pit River Bridge in addition to beforehand barren earth close to the marina.
A sequence of winter storms that introduced precipitation all through the state in late 2023 and early 2024 helped refill the reservoirs, which began off extra full than traditional because of the epic moist season of 2022-2023.
Officers even launched extra water from the reservoir in February to organize for extra storm water, one thing they’d not performed in almost 5 years.
Lake Oroville, the state’s second-biggest reservoir, crammed up as properly. Knowledge from the Division of Water Assets confirmed it was 100% full on Could 20.
It too noticed water releases however nonetheless reached 128% of its historic capability in early Could.
In all, 16 of the 17 greatest reservoirs in California had been above their historic ranges on Could 21.
Even with this excellent news throughout the state, groundwater remained a priority.
Within the 2023-24 water yr, the state added 4.1 million acre-feet — nearly the amount of Lake Shasta — to its depleted groundwater inventory by sending extra water from rivers into open areas the place it might percolate downward.
Nonetheless, consultants say the state has a protracted method to go and can want extra moist climate and improved groundwater recharge methods to fill a niche of 40 million acre-feet that collected over the past 20 years.
“The spectacular recharge numbers in 2023 are the results of laborious work by the native companies mixed with devoted efforts from the state,” mentioned Paul Gosselin, a deputy director on the Division of Water Assets, in a information launch.
“However,” he mentioned, “we should do extra to be ready to seize and retailer water when the moist years come.”
