Appendix – Delaware River Flood Crests

sample delaware gauging station readoutThe Delaware River, like most others, is measured in depth at United States Geological Service (USGS) gauging stations, generally located at or very near major bridge crossings along its length. Because these depths and the banks that surround them differ, so do flood stages at each station, although some are similar. Another factor affecting actual flood crests at any point along the river is the elevation of surrounding land: where banks are higher, flooding will be less severe.
