Endangered since 1993, the plankton-eating silver minnow is blamed by farmers, lawmakers and water officials up and down the Golden State for locking down billions of gallons of water that otherwise would go to them.

Farmers and downstate cities — already suffering the effects of the drought — claim that water was allocated to them, and withholding it for a fish with no commercial purpose is bad policy.
