Paradox of Plenty: Why California Can Be Wet and Still Short on Water

For much of California’s agricultural history, a wet winter brought relief. Reservoirs filled, rivers ran high, and growers assumed surface water deliveries would follow. Today, that assumption no longer holds. Even in years marked by heavy storms and strong reservoir storage, California water allocation anxiety persists.

The disconnect reflects a fundamental shift in water management. California’s system is now governed as much by regulation, environmental constraints, groundwater limits and operational rules as by precipitation totals. In short, flood years no longer guarantee reliable water.
