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.

- 151 - Flooding of river access roads and low lying areas near the river.
- 150 - Low lying areas in the floodplain will flood extensively. Several river access roads will flood.
