When enemies are in face-to-face combat, they’re often blind to an obvious path to potential compromise.That’s certainly true of water warriors, who have been battling over California’s most valuable and limited resource since statehood.

Agriculture just won a major battle over environmentalists in Congress because of an alliance between House Majority Leader Kevin McCarthy (R-Bakersfield) and Sen. Dianne Feinstein (D-Calif.). But still raging in the Sacramento-San Joaquin River Delta is a decades-long struggle that will affect 25 million Californians and 3 million acres of farmland.
