This watershed supports diverse aquatic life and recreational activities. The plant's operation helps protect downstream water quality in this ecologically sensitive region of the Great Lakes.

The plant discharges into a tributary of the Menominee River, which flows into Green Bay and then Lake Michigan. This watershed is part of the larger Great Lakes ecosystem, which supports diverse fish populations and migratory birds. The area is ecologically sensitive due to its role in maintaining water quality for the bay and lake, making effective wastewater treatment critical for local and regional environmental health.
