Harry S. Truman Dam is located in west central Missouri on the Osage River and in the headwaters of the well known Lake of the Ozarks, which is one of the most highly developed recreational lakes in the entire Midwest. Construction and operation of the Harry S. Truman project has created the potential for directly affecting the water quality of the Lake of the Ozarks. This paper describes the features of the Harry S. Truman project, the development of a water quality monitoring program for the project, and operating experience since closure of the embankment in July 1977. Major fish kills have occurred as a result of supersaturation downstream of Harry S. Truman Dam. Brief periods of depressed dissolved oxygen levels in the tailwater area have also occurred. In both cases structural modifications and adjustments in project operations have provided solutions that will significantly reduce downstream water quality problems.
