This water body supports diverse aquatic life and is a critical freshwater resource for millions. The plant's performance is important for maintaining water quality in the lake and protecting downstream ecosystems.

The plant discharges into the Lake Erie basin, part of the Great Lakes system, which drains into the Atlantic Ocean via the St. Lawrence River. Lake Erie is a vital freshwater resource that supports a wide range of aquatic species and provides drinking water for millions. The watershed includes agricultural and urban areas, making nutrient management a key concern to prevent eutrophication and harmful algal blooms.
