What will California’s water picture look like in the next 12 months? The predictions are literally all over the map. After a measurement of the snowpack in the Sierra Nevada on Tuesday, Jan. 2 found only 7.5 inches of snow — 30 percent of the average depth — the state Department of Water Resources (DWR) put out a statement saying residents should prepare for “flood or dry conditions in the months ahead.”
The last time Lake Oroville neared capacity was four years ago, and very quickly it plunged into drought territory and has seen low water levels until this winter. And now that billion-dollar, renovated spillway is back in use as the reservoir is back at 99% of its capacity.
The Feather River is getting a fair amount of extra water flow these days as Lake Oroville has been releasing water over the last week. Oroville is California’s second-largest reservoir, with a capacity of over 3.5 million acre-feet of water, and also just about at capacity is the state’s largest reservoir, Lake Shasta, which has a capacity of 4.5 million acre-feet and is at 98%.
A cold low pressure system spinning off the coast of California sent bands of rain and snow across the state Wednesday, making travel difficult and adding to an epic mountain snowpack.
Forecasters said the storm was not as strong as the systems that pounded the state all winter, but that chains were required for vehicles on highways through the Sierra Nevada. A section of U.S. 395 on the eastern side of the range was closed due to snowfall.
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.
As wet weather has continued to impact California, some reservoirs across the state are being managed with scheduled releases of water to prevent flooding, according to the California Department of Water Resources.
After 14 atmospheric rivers hit back-to-back this winter, reservoirs began filling quickly. Though most of the major reservoirs aren’t full yet, several are significantly higher than they have been historically. This is especially true in Central California at the Don Pedro, Camanche and Oroville reservoirs, KTLA sister station KRON reports.
The California Department of Water Resources announced Monday that it slowed outflows from Lake Oroville from 35,000 cubic feet per second to 27,500 cfs.
According to a press release issued Monday by DWR, the reduction began at 6 p.m. Monday.
California’s water authorities will spend $15 million in three crucial water management zones within the drought-ravaged southern Central Valley.
The hub of agricultural production in the Golden State, the Central Valley has also faced the most dire impacts from another historic drought, as thousands of wells went dry last year and many communities faced a total lack of safe drinking water.
As California braced for yet another round of winter storms Wednesday, state water officials announced that they were again boosting supplies for water agencies that serve 27 million residents.
The Department of Water Resources said it now expects to deliver 35% of requested water supplies — up from the 30% announced last month — via the State Water Project.
The powerful storms that clobbered California for weeks in December and January dropped trillions of gallons of water, flooding many communities and farms. But throughout the state, the rains have done little to nourish the underground supplies that are critical sources of California’s drinking water.
Thousands of people in the San Joaquin Valley have seen their wells go dry after years of prolonged drought and overpumping of aquifers. And a two-week deluge — or even a wet winter — will not bring them relief.
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.
