Learn about changes in water availability in California from 2013 to 2017 with this gallery of maps, satellite images, and photographs. The maps, based on data from the National Drought Mitigation Center, use colors to convey reductions in the availability of freshwater as a result of drought conditions in the state. The maps consider freshwater, including surface water (e.g., rivers, lakes, and reservoirs), aquifers, and soil moisture. The NASA satellite images of changing snowpack levels on the Sierra Nevada and the photographs of Folsom Lake water levels provide observational evidence of drought conditions in the state.
