Stream Flow

 

There are instruments that collect environmental data throughout the Chesapeake Bay Watershed.  For many, you can look on the internet and see what conditions are like right now - in real-time.

This page links to websites with information on stream flow.  

Why are people interested in stream flow?  Well, one thing people want to know is if streams are flooding -- because flooding is dangerous.  A quick click on Current River Forecasts will let you see if any of the big streams in the Chesapeake Bay watershed are flooding now.  Click on any dot and you can learn how high that stream is and all about the site.

Another thing people want to know about streams is how much water is flowing in them.  Why?  Well, some people like to go canoeing.  They want to know if there is enough water in the stream for them to canoe, or too much for it to be safe.  Other people, including scientists, need the information to help them understand conditions in the watershed.

Whatever the reason, it is easy to get stream flow information for thousands of streams, including one near you.  The U.S. Geological Service maintains river gauge stations all over America, including hundreds in the Chesapeake Bay watershed.   Click on your state's link:  Delaware, Maryland, New York, Pennsylvania, Virginia, West Virginia, and D.C.   The link will take you to a state map with colored dots for every stream flow site.   Try to find your county, and then find the stream flow site closest to your school.  Click on the dot to see how much water is flowing in your stream right now. 

The table below has direct links for stream flow data at selected major (and a few minor) rivers and streams in the Chesapeake Bay watershed.  Are any of these sites near your school?
