The Cumberland River flows through Tennessee and Kentucky before joining the Ohio River, which then feeds into the Mississippi River. This river system supports diverse aquatic life, including several species of freshwater mussels and fish. The plant's operations help maintain water quality in these downstream environments, which are important for recreation and ecological health.
