This year’s drought is on the verge of going from bad to worse for thousands of farmers in the Central Valley. Tuesday, the State Water Resources Control Board approved emergency curtailment regulations. The move impacts 5,700 of the 6,600 water rights holders in the Sacramento-San Joaquin Delta watershed. Assemblyman Adam Gray (D-Merced) says Tuesday’s decision by the board is the wrong approach. He had petitioned the board to vote against the emergency measures.
