The San Diego County Water Authority approved a resolution Thursday declaring an end to the drought in San Diego County. The vote came after an unexpectedly rainy January that has already boosted the Sierra Nevada snowpack to springtime levels. The resolution also called upon Gov. Jerry Brown to declare an end the statewide drought emergency and cancel conservation regulations affecting San Diego. The approval was 25-0 with 8 abstentions. Several board members wanted more time to study the resolution, but authority staff said time was of the essence because the state Water Resources Control Board meets early in February.
