Susquehanna Inundation Maps

The Susquehanna River Basin Commission (SRBC) maintains inundation maps for a number of National Weather Service (NWS) river forecast points across the basin. These maps display expected area of flood inundation that will occur at a specific river stage above flood stage. The maps are available for viewing online, as available, and by request. Available online inundation map libraries can be accessed through the United States Geological Survey and the National Weather Service map viewers (see direct links below). Additional libraries (see “SRBC Map Library” below) can be accessed by sending an email to inundationmaps@srbc.net with the property address and preferred format (.jpg, .pdf, .shp) included in the message. SRBC will respond to your request via email.
