Harry S Truman Reservoir, commonly known as Truman Lake, is Missouri's largest reservoir with over 55,600 acres of water and approximately 950 miles of shoreline. Located in west-central Missouri, this sprawling body of water was formed in 1979 by the U.S. Army Corps of Engineers and is fed by four major rivers: the Grand, Sac, Pomme de Terre, and Osage. The lake is characterized by numerous stumps and trees that were left standing when the reservoir was created, providing excellent fish habitat throughout the water body. Truman Lake is known for its fertile waters, particularly in the upper western end where rivers drain cropland, resulting in higher phosphorous content and greater algae growth that supports a robust food chain. The reservoir offers exceptional fishing opportunities for multiple species and is widely regarded as one of the best catfish lakes in Missouri.
