After several consecutive years of below-normal precipitation, the U.S. state of California is prepar-
ing for its most severe drought emergency in decades. The current drought is due in part to decreased
rainfall along with reduced winter snowpack in the Sierra Nevada mountain range. In 2013, Califor-
nia received less precipitation than any other year since it became a state in 1850. Water conserva-
tion efforts are already in place for many locations. For 2014, there is potential for major agricultural
impacts, and the wildfire danger is expected to be unusually high.
These three images show a portion of California’s Central Valley (left side of the images) and the
neighboring Sierra Nevada mountains as viewed by Landsat in February 2011, 2013, and 2014.
The decrease of winter snow cover can be seen in this progression of images. The reduction of
available water supplies in the Central Valley is also indicated by the changing outlines of Folsom
Lake, Camanche Reservoir, and other lakes and reservoirs in the images.
The Landsat archive contains 40 years of data, which allows users to see changes as they are oc-
curing throughout the Earth’s landscape. To view the image, visit
