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
- 21 - A catastrophic and massive flood will affect homes along the river upstream and downstream from the gage off Old Dial Road. The water level will be four feet deep over the Shallowford Bridge. Rapid flowing flood waters will cause extremely dangerous erosion conditions to the banks and may washout the bridge and damage homes. Flood waters will be 1 to 6 feet in some homes along the river. Portions of Upper Shallowford Road...Shallowford Bridge Road...Old Dial Road and Aska Road will be flooded.
- 19 - Major flooding continues with widespread inundation flooding affecting the woodlands and homes along the river upstream and downstream from the gage off Old Dial Road. The water level will be two feet deep over the Shallowford Bridge. Rapid flowing flood waters will cause extremely dangerous erosion conditions to the banks and may washout the bridge. Flood waters will be 1 to 4 feet in some homes along the river. Portions of Upper Shallowford Road and Shallowford Bridge Road will begin to flood.
- 17 - Major flooding begins. Widespread inundation flooding affects the woodlands and homes along the river upstream and downstream from the gage off Old Dial Road. The water level will be topping the Shallowford Bridge. Rapid flowing flood waters will cause extremely dangerous erosion conditions to the banks and may washout the bridge. Flood waters will be 1 to 2 feet in some homes along the river.
