Water Quality Management Through Project Operationby Walter M. Linder, US Army Corps of Engineers, Kansas, City, MO, USA,
Abstract: Harry S. Truman Dam, a multipurpose reservoir project, is located on the Osage River in the headwaters of the Lake of the Ozarks. Construction of this project created the potential to both improve and degrade the water quality in the Lake of the Ozarks. This paper describes the features of the project, the development of a water quality monitoring program, and operational problems that have occurred since closure of the embankment in July 1977. Major fish kills initially occurred in the tailwaters as a result of super-saturation, while minor fish kills have occurred as a result of low dissolved oxygen levels. Low dissolved oxygen levels in the downstream gate wells has also been a problem. Structural modifications and adjustments in project operations have significantly reduced downstream water quality problems without adversely affecting project performance or authorized purposes.
