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
- 18.5 - This would roughly equal the FEMA 500 year or 0.2 percent flood event. Significant flooding of homes on Plumtree and Edgecliff Drives in Mount Air occurs east of Route 315, with the Powell Waste Water Treatment Plant in southern Delaware County also flooded. Substantial flooding occurs along Rivers Edge Drive and Mount Air Place. Flooding would occur on The Ohio State campus, from along and north of Herrick Drive to Woody Hayes Drive, in areas west of Tuttle Park Place.
- 18 - Widespread flooding occurs in sections of Worthington near the river, with homes flooded along Edgecliff and Plumtree Drives in Mount Air. Some flooding begins at the Powell Waste Water Treatment Plant.
- 17 - This is above the FEMA 1 percent flood. Homes flood along Rosslyn and Kanawha Avenues and Tucker Drive in Worthington, with severe flooding along Edgecliff and Plumtree Drives in Mount Air, and along Olentangy River Road in Powell. Much of Olentangy Park and the bike trail are flooded. Flooding extends onto the back of properties along Masefield Street. The OhioHealth Primary Care facility also floods, with water also approaching the Powell Waste Water Treatment Plant. Whetstone High School may also flood.
