The Mississippi River supports diverse aquatic life and is an important recreational waterway in the region.

The plant discharges into the Mississippi River, which flows into the Ottawa River and then the St. Lawrence River, draining into the Atlantic Ocean. The Mississippi River watershed supports fish species such as brook trout and smallmouth bass, and the river is used for recreation. The plant's location inland, over 50 km from the coast, reduces direct marine impact, but its effluent contributes to the overall water quality of the river system.
