The National Weather Service (NWS) in corporation with the US Army Corp of Engineers (USACE), the United States Geological Survey (USGS), and the City of Frankfort have developed a series of maps showing what sections of Frankfort can expect flooding at various stages. The maps run from 27 feet (4 feet below flood stage) up to 52 feet (3.5 feet above the record crest of 1978). For each foot within this range, maps show the area extent of flooding and the estimated depth. Other map backgrounds are available as well: the areas protected by levees, the locations of the levees, the floodway boundary, the 1% (100 year) floodplain, and the .2% (500 year) floodplain. Also, the areas inundation for minor, moderate, and major flooding are displayed.
You can find the maps at the NWS Advanced Hydrologic Prediction Services (AHPS) website for Frankfort here. A PDF that explains how to use the flood inundation map website is here. A YouTube video demonstrating the website can be found here.
