Southern California Groundwater

  • Released Thursday, October 17, 2013

This animation depicts variations in surface elevation resulting from the discharge and recharge of groundwater basins in Southern California. These seasonal fluctuations, which range between -5 and +5 centimeters (-2 to +2 inches), result from the pumping of groundwater during the dry season (Summer/Fall) and recharge of the basins during the wet season (Winter/Spring). Reductions in elevation, resulting from extraction of groundwater, are shown in orange, while increases in elevation, resulting from the recharge of the basins, are shown in blue.
