ABSTRACT
Lake Taneycomo, located in the Missouri Ozark Hills only a few miles from the Arkansas state line, was formed in 1913 by Powersite Dam. Local interests first brought the aquatic plant problem in Lake Taneycomo to the attention of the Corps of Engineers in 1966, primarily to determine if the Corps could provide assistance in controlling the infestation. Four methods of controlling excessive aquatic vegetation were evaluated. They were chemical herbicide treatments, light restriction, dredging, and bottom sealing. A winter drawdown is probably the best potential method of controlling aquatic plant growth in Lake Taneycomo. Not all aquatic weeds would be eradicated by the drawndown, and significant adverse effect on the fish population is anticipated. The white amur is one of the most promising herbivorous fish for the control of rooted aquatic vegetation. Soluble phosphorus levels were measured since phosphorus usually is considered the first limiting major plant nutrient.
