From the Sacramento Bee:

California water agencies, after suffering three years of drought, are now enjoying an unusual benefit: a tide of cheap water declared "surplus" after a bountiful winter.

State and federal agencies made the water available this year, under special contract terms, for the first time since 2006. The aim is to find a productive use, in cities and on crops, for the weather anomaly that brought more water than state dams can hold.

The water is refilling reservoirs and aquifers all over the state, and putting thousands of acres of farmland back into production.

At times, there literally has been no place to put all the water nature brought to California this year. The surplus sales aim to find new places for that abundance. By dropping the price, state and federal water managers hope an urban water agency might decide to fill its local reservoirs, or that a farm irrigator will be tempted to temporarily flood some land to recharge groundwater.
