Wet December for nation's streams


  • Anonymous


Much of the nation experienced a very wet December, with 60% of the key index gaging stations in parts of 23 states reporting flows within the highest 25% of record, and record high December flows were set on key index stations in at least 14 states, according to the U.S. Geological Survey.

As a further indication of the wet December conditions, USGS hydrologists said that the combined flow of the nation's ‘Big Five’ rivers (Mississippi, St. Lawrence, Columbia, Ohio, and Missouri), which was boosted by runoff from rain-swollen streams, ended the year on a wet note, averaging 1203 billion gallons a day (bgd) during December, almost twice the average for the month and the seventh straight month that flows have been above average.
