New Jersey Flooding Events

USGS reports document New Jersey floods from 1896 to the present. Early spring and winter flooding in New Jersey tends to occur as a result of widespread, steady rain of moderate intensity that falls on frozen ground. Snow and ice melt may increase the chance of winter flooding. Summer flooding resulting from thunderstorms typically occurs in small streams and is of local extent. Late summer and fall flooding associated with frontal storms, tropical storms and hurricanes can be widespread, resulting from heavy intense rains across the entire state. New Jersey's major floods are those that are the most severe in terms of magnitude, areal extent, loss of life, and property damage.

NOTE:  Flood peak discharges and estimates of flood recurrence intervals given in older USGS reports and web summaries may have been revised since their original publication. Check on-line peak flow for current discharges.
