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
- 18.73 - Record stage and flow---19,400 cfs (9/5/1965).
- 17.5 - Access to Weeping Rock Campground is very limited due to high water. One half of Slate Creek Campground may be under water. High water may obstruct passage of bridge on west end of Lincoln County Road 311. High water may also restrict safe passage to water pumping staion on sw side of bridge.
- 16.5 - Flood stage. River begins to overflow into Weeping Rock Campground (immediately below dam) and into Slate Creek Campground (3-3.5 mile downstream). USBR personnel will evacuate campgrounds in event of a flood emergency.
