Massive Fish Kill Reported on Chattahoochee River Following Atlanta Storm
A significant fish die-off has been reported along a 20-mile stretch of the Chattahoochee River west of Atlanta, Georgia, following a severe thunderstorm on May 20, 2026. According to Chattahoochee Riverkeeper, thousands of fish, including species like spotted bass, catfish, and carp, were found dead. The storm brought intense rainfall, with rates of up to three inches per hour, leading to flash flooding and the discharge of stormwater and untreated sewage into the river. Environmental experts suggest that the combination of prolonged drought, high water temperatures, and urban runoff created conditions that were lethal to aquatic life. Investigations by the City of Atlanta’s Department of Watershed Management and Chattahoochee Riverkeeper are ongoing to determine the exact causes of the incident.
