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
- 377 - this is the critical stage for the McLean Bottom Levee. The Highway 23 bridge approach is inundated in Ozark. Numerous roads near the river are impassable. This is an extremely dangerous and life threatening situation.
- 373 - this is the critical stage for the Lower Hartman Bottom Levee. Water covers lanes on the Highway 23 bridge approach in Ozark. Numerous roads near the river are impassable. This is an extremely dangerous and life threatening situation.
- 370 - this is the highest stage experienced since the completion of the navigation system in 1969. Highways 309 and 288 northwest of Paris in Logan County are inundated by backwater up Six Mile Creek. Backwater flooding spreads westward into Franklin County. This will exceed the December 29, 2015 flood when the river crested at 369.07 feet. This is an extremely dangerous and life threatening situation.
