RIVER FLOW & WATER DATA

The U.S. Geological Service maintains river gauge stations all over the country.  In the table below you will find direct links to some stations on major rivers of the Chesapeake Bay watershed.   Links to many more stations are available for all 50 states, including:

Delaware

Maryland

New York

Pennsylvania

Virginia

West Virginia, &

D.C. 

These links provide graphic and tabular stream flow data at stations throughout each state, for as much as 60 days of current data.  Use the blue box part way down the page to set search dates.  With a few clicks of the mouse, you can see data from before the 60 day period too.  Archived data for previous years is available by following the “Summary of all available data” link just below the blue box.  Try exploring floods that you remember.
