A new set of satellite images released by NASA shows the dramatic loss of water storage in the Central Valley due to California's long term drought. According to research by NASA's Gravity Recovery and Climate Experiment Team, the Sacramento and San Joaquin River basins together lost 12 million acre feet a year between 2011 and 2014, largely due to agricultural groundwater pumping. The findings were published in a recent edition of Science Magazine.
