Flood Frequency Analyses
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.
