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
- 386.5 - This is the approximate level during the April 1993 record snowmelt flood.
- 386.3 - This is approximately the lake level during the June 1972 Hurricane Agnes major flood.
- 385 - Significant flooding occurs around the lake. This level is approximately the same as the April 1916 and March 1936 floods. Wind waves will cause unusual land erosion and damage docks.
