NOTE: Forecasts are issued as needed during times of high water, but are not routinely available.

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

In Trion...most of the Mount Vernon Mills buildings...homes on First and Second Streets near the levee...homes and apartments on Park Avenue and Dalton and Cooper Streets are flooded with 5 to 8 feet of water. The water level will top the Dixie Highway bridge. Transportation in and out of the Summerville area will be difficult.
- 23 - Record flooding occurs in sections of Summerville due to tributaries backing up from the high flow on the river. The water level hits the Rome Boulevard bridge and affects The Summerville Times property. In Trion...portions of the Mount Vernon Mills buildings including the personnel office...yards and homes on First and Second Streets near the levee...and athletic fields and other structures off Dalton and Cooper Streets are flooded with 3 to 6 feet of water. The water floods portions of Dixie Highway.
- 22 - Major flooding expands into sections of Summerville due to tributaries backing up from near record high flow on the river. The water reaches the bottom of the Rome Boulevard bridge and affects The Summerville Times property. In Trion...the parking lot and portions of the Mount Vernon Mills buildings including the personnel office...yards and homes on First and Second Streets near the levee...and athletic fields and other structures off Dalton and Cooper Streets are flooded with 2 to 5 feet of water.
