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
- 12 - Maximum Operational Limit of the Gage
- 10 - Water level reaches top of the bridge deck on North Main St. Bridge that crosses the Nansemond River.
- 8.5 - Water enters lower end of Super 8 Hotel parking lot
- 7.5 - Water enters buildings along North Main St north of the gage.
- 7 - Water level exceeds height of bulk head at marina at Constants Wharf
- 6.5 - Water enters North Main St, on the north side of the river, 200 ft north of the tidal gage.
- 5.5 - Shallow flooding is expected in the most vulnerable locations near the waterfront and shoreline resulting in a low threat of property damage. Expect up to one foot of water above ground level in low lying, vulnerable areas. Water begins to flood N Main St near the gage due to water backing up through drains.
