Bathtub Ring

As the level of Lake Mead drops, a white band appears on the rocks above the water line. This white band is called a "bathtub ring". The current bathtub ring seen around Lake Mead has been caused by a decade of drought.

However, 2011 was a great water year. Deep snow pack in the Rocky Mountains has led to a rise in the Colorado River, and more water in Lake Mead. So far this year, the lake has risen almost 30 feet.

 

NASA Earth Observatory has a web page about the drought and it's effects on Lake Mead at http://earthobservatory.nasa.gov/Features/LakeMead/

This web page features images from the Landsat satellite that show a comparison of water levels in the lake from different years.
