NASA Data Reveal Major Groundwater Loss in California

December 14, 2009

PASADENA, Calif. – "New space observations reveal that since October 2003, the aquifers for California's primary agricultural region -- the Central Valley -- and its major mountain water source -- the Sierra Nevadas -- have lost nearly enough water combined to fill Lake Mead, America's largest reservoir."

More evidence that the amount of water used for agriculture in California - from groundwater pumping in the Central Valley to diversions from the Delta - is unsustainable for the long term.

Another Cause of Delta Woes - Groundwater Pumping

This opinion piece in the Sacramento Bee points to excessive groundwater pumping in Sacramento County as another cause of the environmental decline in the Delta.
