the locations of the stations may be beneficial in the use of 

the flood-inundation maps.

Base from Oklahoma State Plane North Projection, North American Datum, 1983.

Aerial photography from U.S. Department of Agriculture (2013).

Highways from Oklahoma Department of Transportation (2014).

Incorporated areas, railroads, and roads from U.S. Census Bureau (2014).

Topographic contours at 10-foot intervals from City of Oklahoma City (2004),

 City of Norman (2007), Intermap Technologies (2014), and U.S. Geological Survey (2014).

Unmodeled inundataion areas (hachured) are assumed to be inundated below the modeled

 flood elevation at the place where they join the modeled inundation area. Actual areas inundated

 will depend on the particular failure mechanism and preexisting flood conditions and may differ

 from the areas shown on the maps. For this reason, isolated inundation areas (those

 disconnected from the main inundation area) were included on the inundation maps.
