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
- 61.33 - the river reaches record stage. Considerable land floods, but no structures except the gage house are known to be threatened. Some cattle may be forced to higher ground.
- 59 - the river reaches bankfull and minor flood stage. The river at this stage is very dangerous, as overland flooding begins. John's Marina, a raft unloading shelter, floods. Otherwise, no other known structures are expected to flood, or damage is expected to occur.
