Water Resources Program 2019-2021

Key Project:

Update Wyoming Valley Flood Inundation Mapping


Priority Water Resources Need:

Improve Community Flood Preparedness


Project Location:

Luzerne, Columbia, Montour, Snyder and Northumberland Counties, Pennsylvania


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.


Challenges:
  • Ensuring continuity of flood mapping between four river forecast points
  • Communicating flood risk in levee protected areas
  • Convincing stakeholders to use mapping for flood preparedness

Key Milestones:
  • •  Deploy Maps on AHPS Website
    (September 2018)
  • •  Conduct Community Meetings
    (December 2018)
  • •  Complete Public Outreach
    (March 2019)
