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.
