The 2,430-acre area lies in Bridgewater and Northwest townships in the northwest corner of Williams County.

Williams County Road R provides access to the area from OH-576. The area can also be reached by Williams County Road 7 from US-20.

Lake La Su An Wildlife Area is on the Wabash end moraine deposited during the Wisconsin glaciation. Originally, the area was a beech-maple hardwood forest containing beech, white ash, white oak, red oak, and sugar maple. This combination of hardwood species still dominates the area. There are also several lowland areas that are poorly drained, forming wooded wetlands. Index of Ohio’s trees from the Division of Forestry.

The wildlife area is moderately to gently sloping with natural drainage to the West Branch of the St. Joseph River which cuts through the middle of the area. Approximately two-thirds of the wildlife area is in woods and brushland. The other one-third is divided between cropland and meadow. The water areas include 14 lakes and ponds ranging from 1/4 acre to 82 acres, over 30 wooded wetlands, and restored wetlands from two to 18 acres.

The purchase of land for this wildlife area began in 1981. Additional land is being acquired as funds become available. Land posted with yellow wildlife area signs is part of Lake La Su An Wildlife Area.

Wildlife management activities include the development and management of grain crops and grassland. Trees and shrubs have been planted along field borders and in odd areas to provide permanent cover for upland wildlife. Woods have been protected and improved and most former crop fields have been returned to meadows to prevent soil erosion on the steeper slopes.

Prior to the Division of Wildlife acquisition, an unexploited fishery had resulted in high-quality largemouth bass and bluegill populations in many of the lakes and ponds. To maintain the quality under public fishing pressure, special management techniques and regulations are being used.
