Florida’s Apalachicola River begins near the state line, but the water that flows downstream and into the Apalachicola Bay also comes from two other sources: Georgia’s Flint River and the Chattahoochee River which forms the border between Georgia and Alabama. These three rivers join to make one complex system meant to be shared but litigated by its users for decades. One could argue no one knows the system – its needs and challenges – better than those charged with protecting each portion. Krysta Brown explores the Apalachicola, Chattahoochee and Flint River System – from beginning to end – with the people known as the Riverkeepers.
