Overlooking the Iowa River, this 28-acre preserve is an upland timber donated to the state by Paul Hursch. The Iowa County Conservation Board manages the area for hiking, birding and other nature study activities. To find the Burr Oak area, drive north of Marengo on V66, east on F-15, 1.5 miles. Access is just east of the driveway. It overlooks a 97-acre lake, known for excellent catfish, crappie, bluegill and bass fishing.
Anglers enjoy the new boat ramp, docks and fish cleaning station.
A beach and swimming area, hiking trails, and seven shelters surround the lake.
