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
- 17 - Flooding never seen before occurs with widespread inundation of the woodlands and pastures upstream and downstream from the gage on Lenora Road.

County officials will have the road closed. The water level will reach the bottom of the USGS gage house which may cause data transmission problems.

Several outbuildings upstream and on the left bank from the bridge will be flooded with around 5 feet of water. The water will be around one foot deep over the single lane wood and steel bridge and portions of the road. County officials will have the road closed.
