WASHINGTON — The El Niño storms drenching California won’t suffice to solve the state’s drought and won’t permanently save the Central Valley’s vulnerable salmon, federal scientists are cautioning.
In an apolitical assessment that comes amid a highly political time, National Oceanic and Atmospheric Administration experts stress that this year’s El Niño bounty is both useful and limited. It might well be followed, moreover, by a swing back to a different kind of weather complication called La Niña.
Not all water demands are going to be met, 100 percent, by the recovery we’re seeing relative to the last four years,” NOAA research meteorologist Martin Hoerling said Wednesday in a news briefing. “There are systemic issues with water supply that go beyond precipitation in any given year.”
California is in its fourth year of drought (http://ca.gov/drought). After a wet December 2014, there was little rain in January 2015. February rains partially filled some reservoirs, including Shasta Lake, which rose from 40 percent to 60 percent of capacity, but the entire state was declared a drought emergency area.
Agriculture, which uses about 80 percent of the state's developed or storable water that can be delivered via dams and canals, fallowed 400,000 or about five percent of crop land in 2014, but over 500,000 acres are expected to be fallowed in 2015. The U.S. Bureau of Reclamation said that most of its Central Valley Project farm water customers would receive no federal water in 2015, while the State Water Project said it would provide 20 percent of contracted water to its farmer customers.
By one estimate, the state's 860,000 acres of almonds each year require three times more water than the city of Los Angeles.
