Updated flood-frequency figures will be developed for the 5 USGS gaging stations along the Delaware River on New Jersey's western boundary. This work will be closely coordinated with the US Army Corps of Engineers, Philadelphia District.

The objectives of this study were to locate and survey in high water marks, determine updated flood frequencies for Delaware River gages in NJ, and publish a report. This is in response to a major flood occurred along the Delaware River on April 3-5, 2005.
