National Water Model Hydrograph
Official NWS streamflow forecasts are produced by NWS hydrologic forecasters for river gauge locations using hydrologic models which are calibrated to that location. This process considers additional guidance and information, including local expertise and experience, to produce the best forecast possible. The NWM output provides supplemental guidance to NWS forecasters and should not be considered an official NWS river forecast.
Flood Impacts
- 76 - This is the flood of record which was set in January 1937. The entire floodplain is inundated. Much of Highway 52 is flooded, and many low-lying residences and businesses must be evacuated. Nearly all of Augusta, Kentucky is under water, as well as Higginsport, Chilo, Foster and Neville in Ohio, with 10 feet or more of water in areas of these communities.
- 70 - Flooding as deep as 8 to 10 feet occurs in Augusta, Higginsport, Chilo, Foster and Neville. A flood of this magnitude is beyond the FEMA 1 percent flood with the entire floodplain inundated.
- 66 - The Villages of Moscow and Neville are completely flooded. Major backwater flooding into creeks and streams occurs over Clermont, Brown, Bracken and Pendleton Counties. Much of Route 52 is under water, and major inundation of homes and businesses occurs in Chilo, Foster, Neville, Augusta and Higginsport.
