This region is ecologically sensitive, supporting diverse aquatic life and wetlands that provide important habitat and flood control.

The plant discharges into the Vermilion River watershed, which flows through southern Louisiana and empties into the Atchafalaya Basin, a vast swamp and river system that drains into the Gulf of Mexico. This area supports diverse aquatic ecosystems, including fish, crustaceans, and migratory birds. The wetlands and bayous in the region are ecologically sensitive and play a crucial role in water filtration and flood mitigation.
