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
- 5 - Observations made on September 14, 2014 suggest that Lake Stage at this level and above will result in water overflowing Power Creek Road. Rainfall events that cause rises of Eyak Lake to this level and above can likely occur in the Sheridan River and Salmon Creek basins located at miles 14 and 23, respectively, on the Copper River Highway with water overflowing these sections of the highway.
