Lake Mead's Water Sinks to Lowest Level Since 1930s

Years of unrelenting drought are straining a large reservoir of water between Nevada and Arizona, new satellite images reveal. Images taken July 25 show that Lake Mead’s water level has dropped by about 120 feet (37 meters) from where the water reached 15 years ago, on July 6, 2000. The Landsat 8 satellite, jointly managed by NASA and the U.S. Geological Survey, captured both photos of the sprawling reservoir.
