River Level
The U.S. Geological Survey (USGS) operates and maintains this real time stream gaging station located on the Chattahoochee River at U.S. 41 is funded in cooperation with the U.S. Army Corps of Engineers, Mobile District, and Georgia Power Company. The USGS Atlanta Field Office is responsible for the management of this station. For additional information about water temperature, discharge and turbidity at this location visit the USGS website at https://waterdata.usgs.gov/ga/nwis/uv?site_no=02335990.
Daily fluctuations in the chart are due to water releases from Morgan Falls Dam.
Above is a view of Paces Mill during the Flood of 2009. To the left is the boat ramp with a view of the river in the distant sunny area. Behind the trash receptacles is the picnic area. The equipment in the fee station was a total loss. This is not the time to be on the water!

Flood Levels As the river level increases at a gaging station the risk for potential loss of life and property increases. Below are definitions for the different flood stages and the damage that can be expected.
Major Flood Stage - Expect extensive inundation of structures and roads. Significant evacuations of people and/or transfer of property to higher elevations becomes necessary.
Moderate Flood Stage - Expect some inundation of structures and roads near stream. Some evacuations of people and/or transfer of property to higher elevations becomes necessary.
Flood Stage - Expect minimal or no property damage, but possibly some public threat.
Action Stage - Flooding becomes a concern. River/stream is approaching or is forecast to approach the gage height - flood stage - where flooding is defined to begin. Flood stage is an established gage height for a given location at which a rise in water surface level begins to create a hazard to lives, property, or commerce.
