As severe drought grips parts of the western United States, a below average flow of water is expected to enter Lake Powell and Lake Mead, the two biggest reservoirs of the Colorado River Basin. Lake Powell is currently at 45 percent of capacity and is at risk of seeing its surface elevation fall below 1,075 feet above sea level by September, which would be the lowest level on record.

Utah and U.S. government officials will launch a study this month to determine the extent of mining pollution in Lake Powell on the Utah-Arizona border.
The Deseret News reports this week that heavy metals washed into Lake Powell over the decades by flash flooding will be dug up from the river deltas to assess metal concentrations.
The study will provide information about how mining affects the lake and the fish that live in it. Researchers will test for levels of arsenic, cadmium, copper, mercury and lead.
The lake is a key part of a water system that provides drinking water to 40 million people in the Southwest.
