Farmers in California’s Central Valley are in for another brutal summer of drought.
The federal government announced initial 2022 water allocations Wednesday for customers of the Central Valley Project, and the figures were dismal: Most irrigation districts in the Sacramento and San Joaquin valleys can expect to receive no deliveries from the project’s vast network of reservoirs and canals.
Water made California.
The statement is often made about what is arguably the largest and most complex water transfer systems ever created by mankind — the California State Water Project — and its kissing cousin the federal Central Valley Project.
Storing water in reservoirs is important for maintaining freshwater ecosystem health and protecting native species. Stored water also is essential for adapting to the changing climate, especially warming and drought intensification. Yet, reservoir operators often treat environmental objectives as a constraint, rather than as a priority akin to water deliveries for cities and farms. Reservoir management becomes especially challenging during severe droughts when surface water supplies are scarce, and urban and agricultural demands conflict with water supplies needed to maintain healthy waterways and wetlands. In times of drought, most freshwater ecosystems suffer.
Farmers on the western edge of the parched San Joaquin Valley have little or no ground water resources this year. The South San Joaquin Irrigation District and Oakdale Irrigation District have legal rights to 200,000 acre feet of water sitting behind New Melones Reservoir beyond this year’s needs of the farms and urban customers they serve. The two districts want to help the farmers who will face a difficult choice: Let tens of thousands of acres of productive orchards die and leave cropland fallow or else accelerate groundwater pumping to exacerbate dropping aquifers the State of California has identified as a pressing issue.
As much as 100,000 acre-feet of water — enough to meet the annual demand of more than 40,000 Tuolumne County residents for at least five years — that’s currently stored in New Melones Reservoir could soon be sent south to aid drought-stricken farmers under an agreement between the Oakdale and South San Joaquin irrigation districts.
On Wednesday, the districts announced their respective boards had approved the proposal that would benefit agricultural contractors on the west side of the San Joaquin Valley who’ve been cut off from their typical annual water supplies through the federal Central Valley Project due to the drought conditions.
A bill aimed at improving the Valley’s two largest canal systems from continued subsidence-driven damage advanced through one house of the California State Legislature on Friday.
Senate Bill 559, a top priority for legislators on both side of the aisle in the San Joaquin Valley and led by Sen. Melissa Hurtado (D–Sanger), seeks to dedicate $785 million in spending for improvements to four sets of waterways, spearheaded by two canals servicing the Central Valley Project: the Delta-Mendota Canal and the Friant-Kern Canal.
Urban water agencies are planning to impose mandatory conservation orders after federal water managers slashed deliveries this week amid a rapidly deepening drought.
The Bureau of Reclamation cut water deliveries from the Central Valley Project by about half. That has prompted the Santa Clara Valley Water District, which serves 2 million residents in the Silicon Valley region, to consider a potential conservation order at its board meeting next month. And the Contra Costa Water District, which serves 500,000 residents in the East Bay, is now planning to vote on one in July.
California’s water supply got cut again Wednesday, with the federal government reducing allocations to cities and farms as the drought intensified.
The U.S. Bureau of Reclamation announced that municipal water agencies that rely on the Central Valley Project will have this year’s allocations slashed from 55% down to 25% — a level not seen since the drought of 2015.
That could put additional pressure on the municipalities around greater Sacramento that depend on supplies from Folsom Lake, whose water levels have sunk dramatically this spring. The reservoir is at 46% of its usual capacity for late May.
It’s not yet Memorial Day weekend, but the Bureau of Reclamation is taking drastic measures because of the California drought. On Wednesday, the Bureau announced that farmers north and south of the Sacramento-San Joaquin River Delta would receive no water from the Central Valley Project. Municipal, Industrial Water Deliveries Cut 30%. In addition, municipal and industrial water-service contractors north and south of the Delta will see their allocations cut from 55% of their historic use to 25%.
With very little water to spare this drought year, water districts struggling with limited or no supplies look to their counterparts in other districts to negotiate water transfers to add whatever flexibility they can.
Districts on the west side of the Central Valley, both north and south of the Sacramento-San Joaquin Delta, face the prospect of receiving no water from the Central Valley Project.
“Water transfers are absolutely critical to preventing a disaster on the west side of the Sacramento Valley this year. Other than groundwater, it’s the only water many of our folks have,” said Jeffrey Sutton, general manager of the Tehama-Colusa Canal Authority; the TCCA, a joint powers authority, serves 17 water districts in Tehama, Glenn, Colusa and Yolo counties.
