NOTE: Forecasts are issued as needed during times of high water, but are not routinely available.
The current flows in cubic feet per second, are approximate and may be affected by debris, aquatic growth, and seasonal ice in the river.
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 - Lowland flooding will continue. Nearby roads in the area will become impassable.
- 17 - Water will overflow the top of the county bridge, and could possibly wash out the bridge. Water will also overflow both banks into agricultural fields and low lying areas.
