Irrigation Water Causing California Drought?

California’s two main river basins and the aquifers beneath its agricultural heartland have lost nearly enough water since 2003 to fill Lake Mead, America’s largest reservoir, new satellite data has shown. California’s 500-mile-long Central Valley is home to one-sixth of all irrigated U.S. cropland. Central Valley farms have increasingly tapped into aquifers during the past few years.
