A 160-acre tract was acquired by the state in 1947 and became known as the Wolf Lake State Recreation Area. Other acquisitions have now increased the area to 580 acres, of which 419 acres are water. The Lake Wolf Lake is a natural lake, but many areas were dredged in years past. It is separated into five different sections by dikes left following the dredging project. The maximum depth is about 20 feet.
