Visible amidst the red and pink hues of the surrounding landscape are the dark waters of Lake Powell, a reservoir on the Colorado River, straddling the border between Utah and Arizona. It is the second largest man-made reservoir in maximum water capacity in the United States behind Lake Mead, storing 24,322,000 acre feet (3.0001×1010 m3) of water when full. Lake Powell was created by the flooding of Glen Canyon by the controversial Glen Canyon Dam.

Two large reservoirs can be observed in this image of western USA: Lake Mead, by the left edge, and Lake Powell, created by the Glen Canyon Dam, by the right edge. Both are important sources of water in this arid region. Lake Mead straddles the Arizona-Nevada border, and Lake Powell is on the Arizona-Utah border. Aqueducts carry water from the system to Las Vegas, Los Angeles, San Diego, and other communities in the Southwest.

There is, however, a 50 percent chance that Lake Mead, which was created by the Hoover Dam and the Colorado River, will go dry by 2021 because of escalating human demand and climate change, according to a study by Tim Barnett and David Pierce of the Scripps Institution of Oceanography of the University of California at San Diego.

By 2017, there is a 50 percent chance that the reservoir could drop so low that Hoover Dam could no longer produce hydroelectric power. Water conservation and mitigation technologies and policies thus need to be implemented now, the study stated.

The disappearance of the manmade lake would create a tidal wave of ill effects for the southwestern U.S. The lake provides water for large cities like Los Angeles and Las Vegas, as well as for several agricultural interests. The power also keeps on the lights in that region of the country.

Lake Powell is a huge reservoir on the Colorado River, straddling the border between Utah and Arizona. It is the second largest man-made reservoir in the United States behind Lake Mead, storing 24,322,000 acre feet (3.0001×1010 m3) of water when full.

Lake Powell was created by the flooding of Glen Canyon by the controversial Glen Canyon Dam. Glen Canyon was carved by differential erosion from the Colorado River over an estimated 5 million years. The Colorado Plateau, through which the canyon cuts, arose some 11 million years ago. Within that plateau lie layers of rock from over 300 million years ago to the relatively recent volcanic activity.

Glen Canyon is a canyon that is located in southeastern and south central Utah and northwestern Arizona within the Vermilion Cliffs area. It was carved by the Colorado River.

Here parts of the canyon appear almost black in color due to the waters of Lake Powell, a reservoir created in the canyon by the Glen Canyon Dam.
