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
- 9 - The town of Lowman will experience record flooding with significant property damage.
- 8.5 - Houses on both sides of the river in the lower section Lowman will flood. Sandbagging will be needed to prevent major damage. Portions of North Shore Drive, Ospree Drive and River Front Road will be flooded.
