NOTE: Forecasts are issued as needed during times of high water, but are not routinely available.
River forecasts for this location take into account past precipitation and the precipitation amounts expected approximately 24 hours into the future from the forecast issuance time.
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

- 24 - Highway 175 just north of Mapleton as well as the airport experience much more widespread flooding.
- 22 - Water affects Highway 175 near the airport just northwest of town.
- 21 - Water begins to flow over the airstrip ramp at the city airport. Farmland, low lying roads, and the airport are generally the only areas affected.
