Thunderstorms over Lake Powell, Arizona

Most photos of Lake Powell highlight the reservoir, created by the construction of Glen Canyon Dam, and its fluctuating water levels. But this photo’s focus is on the sky above the lake—not to mention that flash of lightning—which is as much a part of the amazing scenery here as the rugged sandstone landscape of the region.

Lake Powell is a reservoir on the Colorado River, straddling the border between Utah and Arizona. It is a major vacation spot that around two million people visit every year. It is the second largest man-made reservoir by maximum water capacity in the United States behind Lake Mead, storing 24,322,069 acre feet of water when full. However, due to high water withdrawals for human and agricultural consumption, and because of subsequent droughts in the area, Lake Powell is currently larger than Lake Mead in terms of volume of water currently held, depth and surface area.
Depth: 558 feet (170 m)
Length: 186 miles (299.34 km)
Surface area: 254.06 sq miles (658 km²)
Surface elevation: 3,652 feet (1,113 m)
Mean depth: 131 feet (40 m)
Catchment area: 108,335 sq miles (280,586 km²)
