A river's course seems like a constant feature in the landscape, but river systems can shift around over time. Rivers can even interact with one another in surprising ways, sometimes causing fish and other aquatic life to be redistributed into new regions. Understanding how river systems change their layout, however, requires a closer look at geologic process. The Savannah River system on the Georgia-South Carolina border is one river that has had a dynamic past, and the fish that live in it prove it. This video talks about how fish that should only live in rivers flowing to the Gulf of Mexico ended up in the Savannah, which flows to the Atlantic Ocean. Diagrams outline the processes through which rivers can interact and exchange species while also leaving notable marks on the surrounding landscape.
