Wallace Lake is a freshwater lake in Caddo Parish, in northwestern Louisiana, United States. The lake is much wider than it is tall. However, the actual area of the lake varies drastically annually. It can be from 1,200 to 3,600 ha. The lake has a dam that runs water out to form Wallace Bayou, which combines with Bayou Pierre (Louisiana).
