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.

Due to a gage relocation, the flood stage level has recently changed(9/4/2008). The relocated gage is now on the left bank (upstream side) near the Rising Sun Bridge. The gage was previously 1/2 mile downstream below Mill Dam. Historical data associated with the new gage, such as crests and low water levels, will be listed as they occur. Here are the top four crests associated with the old location...15.49 ft on 06/23/1972...15.43 ft on 09/17/1999...13.89 ft on 08/19/1955...13.83 ft on 09/13/1971. Here are the top four low water records associated with the old location...2.31 ft on 09/13/1995...2.38 ft on 08/19/1963...2.49 ft on 10/31/1963...2.57 ft on 08/31/1965. During winter months, cold and ice may result in inaccurate real-time stream stage and streamflow data. Adjustments or deletions of this data can only be done after detailed analysis.Collaborative Agencies
The National Weather Service prepares its forecasts and other services in collaboration with agencies like the US Geological Survey, US Bureau of Reclamation, US Army Corps of Engineers, Natural Resource Conservation Service, National Park Service, ALERT Users Group, Bureau of Indian Affairs, and many state and local emergency managers across the country.
