Abstract : Procedures for evaluating alternative aquatic plant mechanical control techniques have been described and demonstrated. The demonstration involved predicting the mechanical control system that was most cost-effective in harvesting submerged aquatic plants in Buffalo Lake, Wisconsin. To maintain the treatment areas, i.e. the 276 acres of parallel boat trails and connecting trails, at below nuisance level plants densities would required harvesting 165 acres at an overall density of 5.9 tons/acre in early summer, or harvesting 213 acres at an average density of 7.9 tons/acre by late summer. Total simulated system times required for the Aquamarine H8-650 and the H-400 harvesters working alone with a T-650 transporter to perform the control operation are provided.
