This 55,600-plus acre lake offers 958 miles of coast line and has created a diverse wildlife area rich in the history of Osage Indians, explorers, fur trappers, traders and settlers. Harry S Truman State Park, located on the peninsula that juts into the lake, opened in 1983.

Clear waters, dramatic bluffs and vibrant summer and fall colors make Harry S Truman State Park an ideal place to vacation. The park offers a marina, ample fishing and boating opportunities and water that are ideal for every kind of swimmer. Hiking trails, picnic areas and campsites that dot the park’s open oak woodlands, natural grasslands and lakeside areas let visitors enjoy the abundance of wildlife and recreation opportunities at this park.

Truman Lake is a great location for fishing, even in the winter, as power from Truman Dam helps heat the water. Truman Lake is nationally known for its excellent crappie and bass fishing. The reservoir is fed by four rivers and several small streams, creating a broad diversity for fishing.

More than 8,800 acres of timber were left standing in the lake to improve aquatic habitat. The lake often hosts major fishing tournaments.
