This lake boasts a park with relaxing picnicking areas as well as a shoreline area restored by the City of Bloomington. Native plants provide habitat for pollinators while filtering the pollutants out of water as it flows across the land. It also deters geese from congregating next to the lake.


Water Quality

Penn Lake has high levels of nutrients, including phosphorus, which causes algae growth. The algae limits the recreational uses of the lake to holding stormwater and scenic viewing.

Lower Penn Lake has great bird watching. In the spring, mergansers and loons visit the lake. Whether canoeing in the summer or cross country skiing under a full moon in the winter, you feel like you are far away from the big metropolitan area when you are on this lake. –Lisa McIntire, volunteer lake monitor
