Loon Lake is located in Iosco County, 2 miles north of Hale off of M-65. Loon Lake covers approximately 417 surface acres, with a maximum depth of 128 feet, making it the 9th deepest lake in the State of Michigan. Shallow water areas comprise only 17% of the lake’s total acreage, so sound management of this critical habitat is essential for warm-water fish species and water quality. The lake outlets to Smith Creek which flows to the East Branch of the AuGres River. There is an intermittent creek, Maggie Creek, coming into the lake. The East Branch of the AuGres becomes Whitney Drain and discharges to Saginaw Bay of Lake Huron north of Point Lookout. The lake drops off very steeply. The bottom in the shoals is mostly sand, gravel, marl and fibrous peat; in the depths it is pulpy peat. The lake supported a historic population of Cisco, making it a water body of exceptional interest with the Michigan DNR. Loon Lake is an All-Sports, Multi-Use lake, meaning that fishermen, pleasure boaters, recreational watercraft sports, and swimming are all welcomed and encouraged to enjoy the lake responsibly.
