The crystal-clear waters, surrounded by sandy beaches and towering aloft a red-red-walled canyon, reminiscent of the alien landscapes - all this is Lake Powell, an artificially created body of water on the Colorado River. It lies in the two US states, beginning in northern Arizona and extending to southern Utah, including a large part of the lake. The total area is 658 square kilometers (the maximum length - 299 km, maximum width - 40 km), the volume of water during high water is 30 cubic kilometers. These dimensions make it the second largest after Lake Mead reservoir in the United States. The average depth of the lake is about 40 meters, and in the deepest areas can reach 170 meters.
