The ongoing drought in the western United States is evident in the water levels of Shasta Lake, a large reservoir in northern California that counts on rainfall for replenishment. Low water levels can lead to hazardous conditions for local recreation. Many more people are affected by how this limited water resource is allocated for ecological, urban, and agricultural needs downstream.

The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on Terra acquired these simulated true-color images of Shasta Lake. The top image shows the lake on September 14, 2005, and the bottom image was acquired on September 2, 2014. Read more
