Low Water in Lake Mead (2003)
Thumbnail Image:
File:
Description:
About 96% of the water in Lake Mead is from melted snow that falls in Colorado, Utah, New Mexico, and Wyoming. The past two years have brought severe drought to the western states, and Colorado River runoff has been far below normal during this period. The effect is a drop in lake levels that is visible from NASA satellites. One of NASA’s Earth Science Enterprise research focus areas is the global water and energy cycle governing the precipitation, evaporation, storage and runoff of water. The Earth Science Enterprise Applications Program facilitates the practical use of this knowledge by national and regional decision makers for better management of fresh water resources.
