Substantial rainfall in Northern and Central California during the last few weeks will enable the U.S. Bureau of Reclamation to increase water deliveries to Central Valley farmers to 80% of normal and fully meet its contracts with most municipal customers, federal officials said. “Thank God for the rain,” said Jason Peltier, head of the Central Valley Water Assn. “We’re out of what was really a crisis situation. . . .” However, the officials said some areas--including San Francisco, the Santa Clara Valley and the eastern side of the San Joaquin Valley--still aren’t guaranteed full deliveries because the rains skipped portions of the Sierra watershed that supply them.
