Lake Ballinger is a 103-acre lake with a 3-acre island, jointly owned by the Cities of Mountlake Terrace and Edmonds. The Lake Ballinger Park, 2-acre park, is located on the east shore of the lake and south of the Lake Ballinger Golf Course, and offers one of the only access points to the lake. Year-round fishing is available. Amenities include a boat launch for non-gas powered boats, a fishing pier, beach access, picnic tables, barbecue grills, and restroom facilities.

Before 1888, the lake was called Lake McAleer and the island was homesteaded by Ira and Julia Bartholomew. The lake was subsequently sold to Judge R.A. Ballinger, a one-time Seattle Mayor, who renamed the lake for his father, R.H. Ballinger, who was an officer in the Civil War.
