Low Water in Lake Meade DLESE Reviewed Collection
This lithograph shows images from NASA?s Landsat 7 Enhanced Thematic Mapper Plus instrument of the Boulder, Virgin, and Gregg basins that comprise the southern portion of Lake Meade. About 96% of the water in Lake Mead is from melted snow that falls in Colorado, Utah, New Mexico, and Wyoming. During the period from May 2000 to April 2003 severe drought occurred in the western states, and Colorado River runoff was far below normal. Noticeable differences in water levels can be seen in these images. The top image shows the area on May 3, 2000; the bottom image is from April 19, 2003. Noticeable differences in water levels can be seen.
