Flood Frequency Information

This section of the MARFC website is devoted to flood frequency analysis information for the MARFC forecasting area. It contains information on how many times floods have happened in a specific month, percentages of flood occurrence for each month, probability, and average height above flood stage.

The main function of this project is to give the user historical flood statistics for all of The Middle Atlantic River Forecast Center (MARFC) forecast points. MARFC has received numerous requests from our customers in regards to historical flood information. This project answers these requests for the much needed information.

Flood information is available in an Access database. Please email us if you are interested in receiving a copy.


What's New - 11/5/2014

As of 11/5/2014 ... the "Top Five Low Stages" have been updated with the latest low stage information. However a couple of points could change during the next couple of days.

The Potomac River at Edwards Ferry near Poolesville, MD is a new forecast point and has been added to our flood information. However no floods have occurred there so far.

We would like to thank The Pennsylvania State University meteorology students for writing up weather summaries for some of our floods in the 1960s and 70s.

All other flood information is up to date.
