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
- 32.5 - This is a serious flood episode. Follow the direction of your local emergency management officals. If asked to evacuate, do so immediately. All flood protection measures must be rushed to completion in flood prone areas. Flooding is likely from below the Holyoke Dam through Chicopee and West Springfield.
- 29 - Flooding will continue to spead across low lying areas from Holyoke south through Agawam. Inundation of areas which are outside of local levee protection is likely.
- 28 - Flooding will affect low lying areas along the river which fall outside of levees and flood protection walls.
