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
- 40 - Major flood, widespread flooding of agricultural lands from Geneseo to Scottsville. Some residential and industrial areas threatened.
- 37 - Moderate flood, more widespread flooding of agricultural lands from Geneseo to Scottsville. Residential areas begin to be threatened.
- 33 - Flood stage, river overflows at many areas from Geneseo to Scottsville, but mainly in agricultural lands with little damage to structures.
