SACRAMENTO — Full reservoirs and an abundant snowpack have enabled the Central Valley Project to promise full allocations of water to many valley farms, federal officials announced Feb. 28.
Citrus growers in the eastern San Joaquin Valley’s Friant division will get 100 percent of their contracted supplies after most went without federal surface water in 2014 and 2015 and received 75 percent last year.
“We are extremely pleased with that announcement,” said Laura Brown, director of government affairs for the Exeter-based California Citrus Mutual. “We were expecting it with all the rain we’ve had.”
Among others promised their full supplies are customers of the Central San Joaquin Valley Conservation District and Stockton East Water District and urban customers in the Sacramento area and eastern San Francisco Bay area served by water from the American River.
Settlement contractors on the Sacramento and San Joaquin rivers were told in mid-February they would get their full supplies based on the volume of inflow to Shasta Lake, officials said.
The agency will wait until mid-March to determine other allocations, including those for the west side of the San Joaquin Valley, which only received 5 percent last summer despite late-season storms that provided more water elsewhere.
Several factors will determine the remaining allocations, said Ron Milligan, a U.S. Bureau of Reclamation operations manager in Sacramento. They include the state Department of Water Resources’ third manual snowpack survey, which was set for March 1, as well as reservoir levels and hydrologic conditions, he said.
But Milligan and other federal officials acknowledged in a conference call with reporters that the delay is also partly caused by the National Oceanic and Atmospheric Administration’s failure to complete its fisheries’ temperature management plan for Shasta Lake. The plan could require more water to be kept in the lake this summer to provide cold water for federally protected winter-run chinook salmon.
“Growers are making their planting decisions now,” said Ryan Jacobsen, the Fresno County Farm Bureau’s chief executive officer. “Farmers cannot make choices on what might be an allocation … They need real numbers.”
Jacobsen said Westside growers aren’t expecting a full allocation, which he said is “unacceptable” considering that snowpack levels in most areas are more than 150 percent of normal and outflow from the Sacramento-San Joaquin River Delta has totaled more than 24 million acre-feet since October. Hundreds of thousands of acres on the Westside have been fallowed in recent years because of a lack of water.
But Pablo Arroyave, Reclamation’s acting Mid-Pacific regional director, said the lack of an allocation for the Westside now doesn’t mean the area won’t get water. He said the agency will take advantage of the current hydrology to try to get as much water as possible to districts.
A substantial amount of CVP water is already in storage south of the Delta, and federal share of the San Luis Reservoir west of Los Banos, Calif., is expected to be full within the first week of March, officials said.
Given the large snowpack and high river flows this year, much of the water already in storage will be available for delivery to CVP contractors this spring and summer, they said.
For the CVP overall, this was the first year of widespread 100 percent allocations for agriculture since 2006, officials said. The Friant Division’s supply comes as Millerton Lake near Fresno was at 82 percent of capacity and 126 percent of normal as of Feb. 27, prompting dam operators to boost releases to make room for a big anticipated snowmelt.
The full allocation applies to the division’s Class 1 customers, or the most senior landowners, while customers may take Class 2 supplies as long as the ramped-up releases from Millerton Lake continue, the bureau noted in a news release.
The bureau typically announces its initial allocations in mid-February, although it waited until April 1 last year to take into account anticipated storms in March while giving informal reports to water districts, spokesman Shane Hunt said at the time.
The 2016-17 water year has been “extreme” so far, prompting Reclamation to take “an approach to the announcement of CVP water allocations this year that differs from our historic practice,” Arroyave said. In future years, the agency will strive to release initial allocations for all water users in February, he said.
The State Water Project initially allocated 20 percent of contracted supplies in late November and has so far upped its anticipated deliveries to at least 60 percent of requested supplies. The last time the project’s 29 contracting agencies got their full allocations was in 2006.
