The lake was formed by the construction of the Salamonie Dam, completed in 1966 to mitigate flooding in the Wabash River Valley.
The reservoir covers land that was once the site of the town of Monument City, which was intentionally flooded during the project's creation.
The site hosts an 'Interpretive Center' that features a reconstructed mammoth skeleton found in the region.
The property is part of a larger complex known as the Triple Reservoirs, alongside Mississinewa Lake and J. Edward Roush Lake.
Salamonie Lake is a 2,855-acre reservoir created by the U.S. Army Corps of Engineers for flood control in the Wabash River basin. The property is managed by the Indiana Department of Natural Resources as part of the Upper Wabash Interpretive Services. Visitors can access over 13,000 acres of surrounding state forest lands for hiking, horseback riding, and hunting. The lake serves as a significant regional hub for boating, fishing, and water sports, featuring multiple boat launch ramps. The onsite interpretive center offers educational exhibits regarding the natural history and archaeology of the Salamonie Valley. Winter activities include snowmobiling and cross-country skiing when conditions permit. The area contains extensive camping facilities, including sites with full electrical hookups.
