Truman Dam / Visitors Center

Harry S. Truman Dam and Reservoir
Construction of the Harry S. Truman Dam and Reservoir began in August 1964 and was completed in October 1979. Managed by the U.S. Army Corps of Engineers, Truman Lake area encompasses 259 square miles of land and water.

The project was initiated for flood control measures and is the largest flood control lake in the state of Missouri. At normal pool the lake covers 56,000 acres, but when the pool is at the top of flood control the number of acres increases to 200,000, spreading into portions of four counties: Benton, Henry, Hickory and St. Clair.

Visitor's Center
Atop of Kaysinger Bluff, with a spectacular view of Truman Lake, the Visitor’s Center offers a wide variety of exhibits. From reproductions of archeological fossils found in the area, to paintings of Mastodons, and a timeline showing the exploration and settlement of the Osage River Valley. The Center’s observation deck gives visitors the opportunity to get a bird’s eye view of the dam and portions of the lake.


Walk beyond the Visitor’s Center to Kaysinger Bluff Nature Trail and take a stroll back in time. Experience the White Oak Cabin, and then travel down the trail to the Hooper House and Farm Complex. Each October this area comes alive during Heritage Days as artisans from the past demonstrate their craft. Visit the Harry S. Truman Dam and Reservoir website.
