California has lost more groundwater than held in all its reservoirs

California’s Central Valley has lost roughly 85 cubic kilometers of groundwater storage since 2004 due to intensive pumping during periods of drought. The Central Valley is one of the most productive agricultural regions in the world, growing 40 per cent of the fruit and nuts produced in the US. When surface water is inadequate to irrigate all those crops, farmers pump groundwater from the region’s aquifer. Read More

Helping Nature Store Our Water

For more than a century, we have cultivated our relationship to the community, to one another, and to the land itself. We are stewards of the San Bernardino Valley water basin and the native species of the wash above it.

Water that would otherwise flow to the ocean is diverted and recharged by us for use in the long hot summers and during droughts. We also help manage the Bunker Hill Groundwater Basin with the Cities, Districts, and Agencies in the upper-watershed: in partnership we store and bring ample high-quality water for all uses.

We take a fiscally prudent, pragmatic approach towards fulfilling our mission so that the water supply and the environment it depends upon will be forever protected and available for the community’s use.
