Federal forecasts reveal that water flows into Lake Powell are expected to be only 76 percent of the seasonal norm this year, a drop from the 81 percent prediction made earlier this month.

A WaterWatch map from the U.S. Geological Survey (USGS) shows countless rivers have already reached flood stage, with some of those rivers being measured 1,000 percent of their normal level or more.

Severe drought on Lake Superior’s western shores brought the big lake’s water level down in August, dropping below the normal seasonal average for the first time in more than seven years.
