A massive fish kill was reported on the Chattahoochee River, west of Atlanta, with environmental organization Chattahoochee Riverkeeper estimating thousands of dead fish along a 20-mile stretch. Executive director Jason Ulseth discovered the fish during a patrol, noting the presence of spotted bass, catfish, and other species, some weighing up to 30 pounds. This die-off occurred after a thunderstorm dumped three inches of rain per hour, leading to flash flooding and overwhelming the river, which was already low due to drought. Investigations by Chattahoochee Riverkeeper and the City of Atlanta's Department of Watershed Management are ongoing, with initial findings suggesting that both drought conditions and stormwater contamination contributed to the incident. An unidentified black substance was found along the river banks, and evidence of sewage contamination, including condoms and wet wipes, was also reported. The situation has raised concerns about the long-term effects of urban runoff and sewage discharge into the river.
