A Hidden River Flows Under the World’s Busiest Airport

ATLANTA USA – Many people know that Aventure’s hometown airport is the world’s busiest. Lesser known is that Hartsfield-Jackson Atlanta International Airport sits above the headwaters of one of Georgia’s major waterways. The Flint River begins as small streams near Atlanta’s airport and flows south through Georgia for about 344 miles.

As Hartsfield-Jackson celebrates its centennial this year, the airport continues to balance its growth with protecting the river at its source. Long-running efforts in conservation and stormwater management have helped safeguard this important waterway despite the airport’s immense activity above it.

The Flint River supports wildlife, agriculture, and communities across southwest Georgia, making its quiet beginnings under the world’s busiest airport all the more remarkable. The two share a long history on the south side of Atlanta, one shaping global aviation, the other sustaining the region’s natural landscape.

For 100 years, the Flint River has been a part of Atlanta’s airport. It’s a reminder of the enduring connection between Atlanta’s natural environment and its role as a global aviation hub.
