What this means

Low water at South River at Flakes Mill Road near Atlanta: the gauge reads 2.01 ft, below normal for late October.

That puts it 0.24 ft below the median of 2.25 ft for late October, based on 14 years of readings. It is 10.99 ft below the flood stage of 13.00 ft. A year ago it stood at 2.01 ft as well.

The level has held steady over the past 24 hours. Without real rain upstream, that is unlikely to change quickly.

Fall is often low-water season on rivers, and it usually takes a few days of steady rain to change that. The sensor also reports a water temperature of 58 °F.

What happens at each level

25.00 ft: Major flooding begins with widespread inundation along the river. The Flakes Mill Road bridge forms an obstacle and acts like a dam causing some backwater and erosion eddies to the sides of the bridge. The service road leading to the Snapfinger Advanced Wastewater Treatment Facility will be under water. The west and south sides of the property will be completely flooded with water spilling into the holding areas of the Inflow Channel. Some homes on Roundtable and English Valley Drives will begin to flood.
23.00 ft: Significant flooding expands further from the river. The Flakes Mill Road bridge begins to form an obstacle and act like a dam causing some backwater and erosion eddies to the sides of the bridge. The flood waters will cut off large portions of the service road leading to the Snapfinger Advanced Wastewater Treatment Facility. Parking lots and large portions of the west and south sides of the property will be completely flooded. Backyards of Roundtable and English Valley Drives will also be flooded.
21.00 ft: Significant flooding expands into the woodlands upstream and downstream from the gage on Flakes Mill Road. The water level reaches the bottom of the bridge and county officials may close it. The flood waters will cut off portions of the service road leading to the Snapfinger Advanced Wastewater Treatment Facility. The parking lots south of the administration building on the property will be under two feet of water. Flooding in backyards of homes on Roundtable and English Valley Drives continues to deepen.
19.00 ft: Moderate flooding begins. Significant flooding expands further into the woodlands along the river upstream and downstream from the gage on Flakes Mill Road. The Chapel Park west of the gage will be completely flooded. The flood waters will cover low portions of the service road leading to the Snapfinger Advanced Wastewater Treatment Facility...and affect the parking lots south of the administration building on the property. Flooding begins in backyards of homes on Roundtable and English Valley Drives.
17.00 ft: Minor flooding expands further into the woodlands along the river upstream and downstream from the gage on Flakes Mill Road. Large portions of the Chapel Park west of the gage will be under 4 to 5 feet of water. The flood waters will approach low portions of the service road leading to the Snapfinger Advanced Wastewater Treatment Facility.
15.00 ft: Minor flooding continues to expand further into the woodlands along the river upstream and downstream from the gage on Flakes Mill Road. Large portions of the Chapel Park west of the gage will be under 2 to 3 feet of water.
13.00 ft: Flood stage is reached. Minor flooding will occur in the woodlands and natural flood plain of the river upstream and downstream from the gage on Flakes Mill Road. Portions of the Chapel Park just west of the gage will begin to flood.
