NOTE: Forecasts are issued as needed during times of high water, but are not routinely available.
Automated gauge readings are now available, courtesy of the USGS.
River forecasts for this location take into account past precipitation and the precipitation amounts expected approximately 48 hours into the future from the forecast issuance time.
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

A home off of Blacks Bluff Road will be flooded one to two feet deep. The water level will be two feet deep in the USGS gage house with a loss of data transmission.
