On Wednesday California will likely revise its drought rules, ending a year of local conservation quotas handed down by the state.

The water board will abandon its formula — decried by some local agencies as a “one-size-fits-all” model — which required each water district to curb water use by a certain state-mandated percentage and instead, let districts determine how much they should save.

It won't be a free-for-all. Under the staff proposal being considered today by the State Water Resources Control Board, local suppliers would need to apply hypothetical “stress tests.” Their savings targets would then be based on anticipated water shortfalls over the next three years — assuming the next three mimic the last three in terms of water demand and drought conditions.

“We're making a shift that recognizes the supply conditions have improved,” said the water board's Max Gomberg. “We're setting up something that is going to be in place, really, for the future.”

The state water board says it's partially reacting to more than 150 disgruntled letters it received. But however maligned, the emergency system of state-imposed quotas largely worked.

Over Governor Jerry Brown's declared nine-month drought emergency, from June 2015 to February 2016, urban consumers saved 1.19 million acre-feet of water, compared to 2013. That's enough to supply nearly 6 million people for a year, and fell just short of the governor's 25 percent goal.

Among the state's 411 largest water districts, 199 or just under half, met or exceeded their cumulative goals.

Standouts included Cambria Community Services District, Menlo Park, Dublin San Ramon Services, Soquel Creek Water District and Santa Barbara — each saved 20 percent more water than state water officials required.
