Kayaking (lower left) in Reflection Canyon beneath the towering 140-foot tall 'bathtub ring' of Lake Powell. At this level, the reservoir has lost nearly 70% of its total water volume. The height of the ring reveals just how much was has been lost since the reservoir was last full in 1999. Beginning in 2000, five successive years of Western drought had drastically reduced the inflow to the reservoir and the water volume by the time this image was captured in April 2005.
