This historic flood map represents modeled maximum flood extents from a high-resolution inundation model for Washington, D.C., and surrounding areas during the 1936 Potomac River Flood. River discharge measurements recorded by the United States Geological Survey (USGS) were used to drive the hydrodynamic model from the Little Falls, MD. Verified water level measurements from the National Oceanic and Atmospheric Administration (NOAA) gauge at Washington DC were used to verify timing and flood heights in 1936. Finally, visual spatial comparison between a historic flood impact area map in the Capitol Mall area prior to the implementation of levees in Washington, D.C. was made using the 2008 National Capital Planning Commission (NCPC) report.
