NOTE: Forecasts are issued routinely year-round.
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
- 33 - A large portion of Bound Brook is protected by the flood reduction project. Pump station operations become critical, at this stage, for the continued protection of the borough.
- 30 - Main Street is protected by flap valves/sluice gates. This level triggers the gate closures to protect Main Street.
- 28 - Backyard and low areas are protected by levees and the flood wall. Without the levees or if there is a breach in the levees, minor flooding will occur.
