ABOUT PENN LAKE
Penn Lake, just east of Highway 35W in Bloomington, is a shallow lake with opportunities for bird watching, picnicking, and canoeing.
Water quality of Penn Lake is poor, with average phosphorous levels higher than state standards for shallow lakes. Phosphorous is the nutrient that fuels algae and plant growth and can lead to unwanted algae blooms in a lake. Penn Lake’s water quality limits activities on the lake, but there is a picnic area perfect for watching wildlife and canoeing is allowed, along with fishing.
