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
- 16 - Widespread flooding commences with the 100 year flood being affected at a stage height of 15.8 feet.
- 13.5 - Water begins to flow over the bridge at the gage site.
- 11 - Flooding will be occurring in the town of Surprise. This level is similar to the flood experienced in 2008.
- 10 - Water reaches the bottom of the bridge near the gage. The resulting backwater will eventually close Miller Street, also known as County Road D going south of town.
- 7 - County road 24 1/2 will begin to flood downstream of Surprise. In addition, the city park near the gage site begins to flood.
