This watershed supports diverse aquatic life and provides water resources for communities downstream.

The plant's discharge enters local waterways within the Cumberland River basin, which flows into the Ohio River and eventually the Mississippi River. This watershed supports a variety of fish and wildlife species, including several species of freshwater mussels and game fish. The area is part of the Interior Plateau ecoregion, characterized by rolling hills and agricultural land use.
