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
- 1530.2 - The emergency dike would be topped.
- 1523.2 - Coulees and farmland will begin to flood. Several homes in the immediate vicinity have historically been affected above 22 feet.
