This connection to the Great Lakes system underscores the importance of effective treatment to protect downstream aquatic ecosystems and recreational water quality.
Environmental context
The plant's discharge enters a tributary of the St. Joseph River, which flows through northern Indiana and southern Michigan before reaching Lake Michigan. This watershed supports diverse aquatic life, including fish species such as walleye and smallmouth bass, and provides habitat for migratory waterfowl. Protecting water quality in this basin is critical for maintaining the ecological health of Lake Michigan's nearshore zone.
