UNCERTAINTIES AND LIMITATIONS FOR USE OF FLOOD-INUNDATION MAPS

Although the flood-inundation maps represent the boundaries of inundated areas with a distinct 

line, some uncertainty is associated with these maps. The flood boundaries shown were estimated 

based on water stages (water-surface elevations) and streamflows at selected USGS streamgages. 

Water-surface elevations along the stream reaches were estimated by steady-state hydraulic 

modeling, assuming unobstructed flow, and using streamflows and hydrologic conditions 

anticipated at the USGS streamgage(s). The hydraulic model reflects the land-cover characteristics 

and any bridge, dam, levee, or other hydraulic structures existing as of November 2012. Unique 

meteorological factors (timing and distribution of precipitation) may cause actual streamflows 

along the modeled reach to vary from those assumed during a flood, which may lead to deviations 

in the water-surface elevations and inundation boundaries shown. Additional areas may be 

flooded due to unanticipated conditions such as: changes in the streambed elevation or roughness, 

backwater into major tributaries along a main stem river, or backwater from localized debris or ice 

jams. The accuracy of the floodwater extent portrayed on these maps will vary with the accuracy of 

the digital elevation model used to simulate the land surface. Additional uncertainties and 

limitations pertinent to this study are described in the document accompanying this set of flood 

inundation map sheets.

If this series of flood-inundation maps will be used in conjunction with National Weather Service 

(NWS) river forecasts, the user should be aware of additional uncertainties that may be inherent or 

factored into NWS forecast procedures. The NWS uses forecast models to estimate the quantity 

and timing of water flowing through selected stream reaches in the United States. These forecast 

models (1) estimate the amount of runoff generated by precipitation and snowmelt, (2) simulate the 

movement of floodwater as it proceeds downstream, and (3) predict the flow and stage 

(water-surface elevation) for the stream at a given location (AHPS forecast point) throughout the 

forecast period (every 6 hours and 3 to 5 days out in many locations). For more information on 

AHPS forecasts, please see: http://water.weather.gov/ahps/pcpn_and_river_forecasting.pdf.

DISCLAIMER

Inundated areas shown should not be used for navigation, regulatory, permitting, or other legal 

purposes. The USGS provides these maps “as-is” for a quick references, emergency planning tool 

but assumes no legal liability or responsibility resulting from the use of this information.
