About Penn Lake
Penn Lake is a shallow located in Bloomington. Penn Lake‘s water quality is poor, with average phosphorus levels higher than state standards for shallow lakes. The Minnesota Pollution Control Agency has designated Penn Lake as impaired under a total daily maximum load threshold. In simple terms, this means the lake is unhealthy. Nine Mile Creek Watershed District and the City of Bloomington are working together to develop a plan to improve water quality conditions in the lake.
