City officials say drought left the river low and warm, limiting its ability to absorb the stormwater heat and nutrients, while Chattahoochee Riverkeeper and the City of Atlanta are investigating the role of stormwater and potential sewage discharges. Preliminary data suggests the tunnel system operated within permits, but tests are ongoing as investigators look into contributing factors and water quality impacts.

This is the first overflow this year, with improvements from the Big Pipe project significantly reducing the frequency of overflows compared to before its completion in 2011.
