Graphical representation of flood inundation for NWS flood categories are based on steady state hydraulic modeling of water surface elevations for incremented discharges. Map shows approximate inundation areas for given water surface elevations and should not be used for navigation or permitting or other legal purposes, but strictly as a planning reference tool.

Site-specific information:
These maps were provided to the NWS courtesy of the USGS.  The technical details for these maps can be found in this USGS Report.  The maps were prepared in cooperation with the Rhode Island Emergency Management Agency and the U.S. Army Corps of Engineers.  Map files were adapted by the NWS to be viewable in AHPS.

Extended rating:
The Rating Curve Extension is calculated by using either a linear, logarithmic, or hydraulic technique to extend the rating curve above the currently established relationship between stage and flow.
