Outside of its 344-mile valley, not many people know about the Flint River, even Georgians. Yet it's upper half is one of the longest free-flowing rivers in the US (saved from a dam by Jimmy Carter and friends in the 70s). And the Lower Flint is one of the nation's most biodiverse regions, with the highest species density of amphibians and reptiles north of Mexico.
It's also extremely threatened, identified by American Rivers as one of the top ten most endangered rivers in the US. Overused in the headwaters by the southern exurbs of Atlanta and by agriculture in the lower valley, the Flint shrinks into itself during increasingly severe droughts. Georgia legislators have been pushing for costly and unproven engineering projects to retain water in the basin, but many folks believe that more simple, affordable and sustainable solutions exist, such as new agricultural tools that increase efficiency and better allocation and return of water in the upper municipalities.
