| 17.0 | Record flooding expands with a few feet of water covering Georgia Highway 90 and the level reaches the top of the bridge. The bridge will be closed and the USGS gage house will be under water. | | 15.0 | Major flooding begins with several inches of water covering Georgia Highway 90 near the stream gage on Georgia Highway 90. The bridge forms an obstacle and acts like a dam causing some backwater and erosion eddies to the sides of the bridge. The bridge will be closed. The water reaches the bottom of the USGS gage house and automated stage readings are unlikely. This level would exceed the record set during Tropical Storm Alberto in 1995. | | 14.0 | Moderate flooding expands into the woodland areas upstream and downstream from the stream gage on Georgia Highway 90. The bridge begins to form an obstacle and act like a dam causing some backwater and erosion eddies to the sides of the bridge. The bridge will likely be closed. This level is near the record set during Tropical Storm Alberto in 1995. | | 13.0 | Moderate flooding expands into the woodland areas upstream and downstream from the stream gage on Georgia Highway 90. The bridge begins to form an obstacle and act like a dam causing some backwater and erosion eddies to the sides of the bridge. The bridge may become closed. | | 12.0 | Moderate flooding begins. Widespread flooding expands into the woodlands upstream and downstream of the stream gage on Georgia Highway 90. Creek access roads will be flooded and the water level reaches the bottom of the bridge. The bridge may become closed. | | 11.0 | Minor flooding expands into the woodland areas upstream and downstream from the stream gage on Georgia Highway 90. Larger portions of creek access roads will flood. | | 10.0 | Flood stage is reached. Minor flooding of woodlands occurs upstream and downstream from the stream gage on Georgia Highway 90. Portions of creek access roads and low lying areas will begin to flood. | | 8.0 | Bankfull conditions are reached upstream and downstream from the stream gage on Georgia Highway 90. |
