A report by the State Water Resources Control Board recommends that new water rights permits be tailored to California’s increasingly volatile hydrology and be adaptable enough to ensure water exists to meet an applicant’s demand. And it warns that the increasingly whiplash nature of California’s changing climate could require existing rights holders to curtail diversions more often and in more watersheds — or open opportunities to grab more water in climate-induced floods.

Does California need to revamp the way in which water is dedicated to the environment to better protect fish and the ecosystem at large? In the hypersensitive world of California water, where differences over who gets what can result in epic legislative and legal battles, the idea sparks a combination of fear, uncertainty and promise.

Saying that the way California manages water for the environment “isn’t working for anyone,” the Public Policy Institute of California (PPIC) shook things up late last year by proposing a redesigned regulatory system featuring what they described as water ecosystem plans and water budgets with allocations set aside for the environment.
