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
- 26 - Estimated historical record flood stage. According to Tennessee Valley Authority historical research, the river reached similar levels in April of 1791. Note, however, that this record cannot be directly compared to more rigorous and accurate streamgauge measurements taken during the USGS period of record. Regardless, catastrophic flooding of the Swannanoa River Valley is ongoing with ruinous flooding impacting most structures within the flood plain.
- 21 - Major Flooding continues. Devastating flooding of the Swannanoa River Valley is likely. Biltmore Village and surrounding areas in the Swannanoa River Valley are experiencing the worst flooding since measurements began in 1920.
- 19 - Major Flooding continues. Significant flooding around Biltmore Village continues including Brook St., Lodge St., Swan St., Angle St., and Boston Way. Floodwater levels are similar to those which occurred during Hurricane Frances in early September 2004.
