Sullivan Lake is a 42-acre lake in Cass County, 50 feet at its deepest. The DNR last surveyed its fish in 1986. Recorded species include northern pike and largemouth bass.
Survey catches show what DNR nets and electrofishing found on the survey date, not how the fishing is today. Check the current regulations and the Department of Health advice before you keep fish, and confirm access conditions before you tow a boat.
