For more than 100 years, groups in the western United States have fought over water. During the 1880s, sheep ranchers and cattle ranchers argued over drinking water for their livestock on the high plains. In 1913, the city of Los Angeles began to draw water away from small agricultural communities in Owen Valley, leaving a dusty dry lake bed. In the late 1950s, construction of the Glen Canyon Dam catalyzed the American environmental movement. Today, farmers are fighting fishermen, environmentalists, and Native American tribes over the water in the Upper Klamath River Basin. The Landsat 7 satellite, launched by NASA and operated by the U.S. Geological Survey, documented an extreme drought in the area along the California/Oregon border in the spring of 2001.

Acquired on April 10, 2010, and and March 7, 2009, these natural-color images show changes in a central Australian saltpan, Lake Frome. In 2010, water has seeped into the salt lake, leaving standing water in some areas and muddying much of the ground surface.

Heavy winter and spring snowfall provided much-needed meltwater, but the effects of long-term drought mean the lake is nowhere near its highs from the 1980s and 90s.

Muddy brown water fills Sandusky Bay, just south of Lake Erie in this astronaut photograph. The small city of Sandusky occupies the southeastern shore of the bay. The most striking aspect of this image is the flow of the brown water in and out of the mouth of the bay. Slight movement of lake surface water, driven mainly by wind, causes a small ebb and flow of bay water. Sediment-charged water is derived from agricultural fields along the Sandusky River upstream. Mud plumes in Lake Erie originate from prior pulses of muddy water from the bay. When this image was taken, some clear, lake water (blue-green strip) appeared to be flowing into the bay.

Astronauts aboard the Space Shuttle and Space Station have tracked regional environmental changes spanning decades. Lake Chapala, Mexico’s largest lake, serves as one example of an area experiencing significant changes that have been well documented from space. Over the past twenty years, the lake’s water levels have decreased in conjunction with increasing development from the fast-growing city of Guadalajara.
