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
- 16 - Widespread inundation of residential areas along the Nashua River is likely. Areas that will be the most impacted include parts of East Pepperell, Hollis and Nashua. Flooding is expected along a stretch of Route 119 in Pepperell. In Groton, potentially affected areas include Fitchs Bridge Road, Long Hill Road, and Route 225. Take action now to protect life and property. Follow the directions of emergency management officials. The standard river gage does not report at this elevation.
- 15 - Flooding is expected in low lying residential areas along portions of the Nashua River. Floodwaters inundate a Pepperell Airport as well as low lying areas on route 119. Know the alternate routes in your location so you avoid areas where flood waters may have damaged or closed area roadways. Follow the directions of local officials and if asked to evacuate do so immediately. The standard river gage can not report much higher than this elevation
- 14 - Flooding is expected in low lying residential areas along portions of the Nashua River. Floodwaters inundate a portion of Route 119 in Pepperell, and also inundate businesses on Route 119 near its junction with Route 111. Know the alternate routes in your location so you avoid areas where flood waters may have damaged or closed area roadways. Follow the directions of local officials and if asked to evacuate do so immediately. The standard river gage can not report much higher than this elevation.
