The plant discharges into tributaries of the Tennessee River system, which flows into the Ohio River and then the Mississippi River before reaching the Gulf of Mexico. This watershed supports diverse aquatic life and is an important migratory corridor for fish and birds. The plant's operations help maintain water quality in local streams that feed into this extensive river network.
