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
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.



Past Projects
The Nine Mile Creek Watershed District has not conducted any major water quality improvement projects on Penn Lake. The District has helped fund several best management projects near Penn Lake including: raingardens, shoreline buffers, habitat restorations, and more. These projects help reduce runoff that enters Penn Lake. The District also provides education on pollution and runoff prevention.
