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.

- 14 - The river may begin to threaten "The Flat" area at this level and the ballfield will begin to experience some flooding.
- 12 - The river begins to overflow the left bank downstream from the foot bridge where the gage is located.
