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 represent unobstructed flow conditions and may be
unrepresentative when ice jams and/or debris are in place.
Extended rating: Rating Curve Extension - 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.
