California Calls for More Water for Fish in Key River Hub

State water regulators say California should leave more water in the state’s main river delta to save crashing populations of native fish.

The recommendations Wednesday in a long-awaited report from the State Water Resources Control Board could lead to cuts in the amounts that cities and farms can take from the Sacramento and San Joaquin rivers delta.

Wednesday’s draft recommendations also could complicate Gov. Jerry Brown’s proposal for building $15.7 billion in giant water tunnels to carry water from the Sacramento River.

The delta provides at least some of the water used by two-thirds of Californians. The new state report says current management of the delta has caused the decline of almost all native species there.

The new findings are expected to be a starting point for regulatory changes.
