California’s management of water is not working for anyone. Environmental advocates argue that state and federal regulators have set water-quality and flow standards that do not adequately protect fish and wildlife, and have not enforced these requirements when they are most needed. Farm and urban interests claim that these regulations have been ineffective and cause unnecessary economic harm. These water users may incur additional cutbacks in their water supplies if regulators conclude that more water is needed to support struggling fish populations, making planning for producers difficult.
