Many California farmers expect to receive full deliveries of irrigation water this year from a vast system of canals and reservoirs run by the federal government, while some in the nation’s most productive farming region will receive a fraction as the state recovers from several years of drought, officials said Friday.

Farms and water customers in the state’s northern Sacramento Valley will get their full water supplies from the U.S. Bureau of Reclamation. It’s a big improvement over last year, when those farmers received no water and neighboring cities got one-quarter of their contracted amounts.
