Flooding in the Delaware River Basin

The Delaware River Basin's flood of record is August 1955. It was one of the primary reasons that led to the creation of the DRBC in 1961.

For the next 50 years or so, the Delaware River Basin experienced some flood events, but nothing like that seen in 1955. That is, until 2004-2006, when the Basin experienced three major mainstem flooding events in roughly two years (September 2004, April 2005 and June 2006).

Different Types of Flooding

  • Flash Flooding: from intense storms, causing street flooding or tributaries to rise quickly

  • Tidal Flooding: in the Delaware River Estuary

  • River Flooding: causes the mainstem Delaware River and tributaries to overflow their banks

During Times of Flooding

it is important to track real-time conditions and flood forecasts to know which areas in the basin may be flooded and when rivers and streams are expected to flood and how much.
