The Sacramento region’s largest water districts have given a resounding answer to the question of whether they could handle three more years of drought: We have plenty of water.

The State Water Resources Control Board last month asked California’s urban water districts to evaluate how much water they would need in the next three years if drought persisted – and whether their supplies would meet that demand. Districts that certify their supplies are adequate will not face mandatory water-use cuts. Those with inadequate supplies must set conservation goals proportional to their anticipated shortfall.
