During 1967, field studies on the Holston River and in the laboratory produced evidence that excessive aquatic plant growths are not soley related to the presence of large amounts of nutrients in water. Factors contributing to growth were the amount of nutrients in sediments, water depth, and turbidity. Water depth and turbidity influence the amount of light which penetrates the water and is available for the growth of rooted plants.
