A 2025 project restored Perch Lake’s natural flow, improving water quality and fish habitat in the St. Louis River Estuary.
Perch Lake’s rehabilitation project, completed in late 2025, has improved water quality and habitat in the St. Louis River Estuary by restoring natural flow, reducing sediment buildup, and supporting native fish and wildlife.
The effort, led by the U.S. Army Corps of Engineers and local partners, involved removing barriers, regrading stream banks, and planting native vegetation.
Early monitoring shows increased fish populations and clearer water downstream, marking a key step in broader estuary recovery.
