The Susquehanna Flood Forecast and Warning System provides flood stage forecast maps for flood prone communities in the basin. Flood stage forecast maps relate extent and depth of expected inundation relative to a forecasted flood crest at a local National Weather Service river forecast point. To display the maps in a web based format, SRBC developed the Susquehanna Inundation Map Viewer (SIMV) in cooperation with their system partners. In addition to the maps displayed on SIMV, SRBC maintains a library of "legacy" flood stage forecast maps that are based on historical data. To inquire about the status of mapping in your community please contact SRBC at email@example.com.
Flood Damage Reduction and Forecast Maps
Structural flood protection, including levees and reservoirs, exists in many communities in the basin. The map presented here displays communities in the basin with structural protection and the location of National Weather Service flood forecast points.
The United States Army Corps of Engineers (USACE) operates and maintains a number of reservoirs in the basin for the purpose of flood damage reduction. Reservoir release information is transmitted to the National Weather Service and incorporated into forecast modeling. Provided here is a link to relevant data about these reservoirs .
AHPS Data (NOAA)
NOAA maintains the Advanced Hydrologic Prediction Service (AHPS) for the purpose of disseminating forecasts and critical hydrologic information. The data provided at this link will allow the user to view river forecast information at a specific flood location .
SRBC Map and Data Atlas
SRBC maintains an online map and data atlas to provide residents of the basin and interested others with relevant information regarding the Susquehanna watershed.
FEMA Map Service Center
FEMA provides regulatory floodplain mapping based on the Base Flood Elevation (BFE). A property that is located within an inundated area as determined by the BFE is subject to local floodplain management requirements and the possible need to purchase flood insurance as required by the National Flood Insurance Program.
