Flood Impacts & Photos Collapse

49 Major flooding continues. Highway 19 Bridge flooded and will need to be closed.
47 Major flooding begins. Highway 19 starts to flood and will need to be closed.
45.7 The record crest was 45.7 feet on July 6...1994. This was a 100 year peak crest. This event was caused by Tropical Storm Alberto which dropped 13 to 15 inches in the headwaters of the Flint River. The Culloden was washed away by the flood wave which resulted.
25 Moderate flooding begins. Access Road to boat ramp and parking lot to boat ramp flood. In addition...flooding of most of the land at the bend of the river upstream develops.
24 Minor flooding expands further into the woodlands and fields along the river upstream and downstream from the gage on U.S. Highway 19. The flood waters will be up to 6 feet deep over the top of the boat ramp and cover a portion of the access road by the bridge on the Taylor County side of the river.
22 Minor flooding expands into the woodlands and fields along the river upstream and downstream from the gage on U.S. Highway 19. The flood waters will be up to 4 feet deep over the top of the boat ramp and cover a portion of the access road by the bridge on the Taylor County side of the river.
20 Minor flooding continues along the river in the woodlands and fields upstream and downstream from the gage on U.S. Highway 19. The flood waters will cover the boat ramp up to two feet deep and cover a portion of the access road by the bridge on the Taylor County side of the river.
18 Flood Stage is reached. Minor flooding begins along the river in the woodlands and low lying areas of fields upstream and downstream from the gage on U.S. Highway 19. The water level will reach the top of a boat ramp by the bridge on the Taylor County side of the river.
Low Water Impacts Collapse
If you notice any errors in the below information, please contact our Webmaster
300 cfs Minimum flow for the stretch from Sprewell Bluff State Park to Po Biddy Road. Some uncertainty to the minimum flow needed.
500 cfs Paddled from Georgia Highway 18 to Georgia Highway 36. Scraped the bottom often. Guidebook says minimum flow for paddling is 300 cfs, but this paddler disagrees and asserts that a much higher flow is needed.

Additional Information Collapse
This site was formerly known as Culloden 13SW. The EMA Directors for Upson and Taylor counties requested the name change due to past confusion on the gage location.

Low water threshold is the 7Q10 value determined by the USGS and published in the Scientific Investigations Report 2017–5001.
