Kayaking in Oak Creek Bay on Lake Powell beneath snow-capped Navajo Mountain with water level of reservoir 140 feet below full-pool elevation. At this level, the reservoir has lost nearly 70% of its total water volume. The white 'bathtub ring' of the reservoir can be seen along the slope above the water line. When the reservoir was last full in 1999, the rounded dome in shadow at left was beneath the surface of the water. Glen Canyon National Recreation Area, Utah. Photo Date: April 25, 2005
