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
- 20 - Major Flood Stage. Extensive flooding along the creek with inundation of structures and roads.
- 18 - Moderate Flood Stage. Some inundation of structures and roads near the creek are possible. Water will cover northbound 385 north of Oelrichs at Horsehead Creek and will begin to approach southbound lanes of Highway 385.
- 17 - Water may begin to approach the northbound lane of Highway 385, north of Oelrichs, about 150 feet south of Horsehead Creek. It typically takes 6 to 10 hours for the water to reach this location.
