Nation's water picture better but southeast still dry

The flow of the nation's ‘Big Five’ rivers, representing stream runoff from about half of the conterminous United States, increased during November and was 13% above normal for the month, according to the U.S. Geological Survey. USGS scientists said flow of these rivers—the Mississippi, St. Lawrence, Ohio, Columbia, and Missouri—increased from 483 billion gallons per day (bgd) during October, a rate which was 2% above normal for the month, to 553 bgd during November. Because of the large area draining into the Big Five, their combined flow provides a quick, useful check on the pulse of the nation's water resources. The Big Five flow has been above average for the last 6 months
