Project Lead:

Project Description:

Susquehanna River flooding The Wyoming Valley in northeastern Pennsylvania has a long history of flooding. The Pennsylvania Silver Jackets, an interagency team focused on reducing flood risk, has developed flood inundation mapping for priority stream reaches in the region. The maps will show an expected area and depth of flooding based on observed and forecasted river stages for the Susquehanna River at Wilkes-Barre, Bloomsburg, Danville, and Sunbury stream gages. The maps will be available on the National Oceanic Atmospheric Administration Advanced Hydrologic Prediction System (AHPS) website and serve as a valuable flood preparedness tool for emergency managers and the public. SRBC, in collaboration with the National Weather Service, will be facilitating dissemination and promotion of the new flood inundation mapping products.
