Abstract:

The purpose of this supplement to the Environmental Impact Statement EIS, 1979 for the Aquatic Plant Management Program APMP is to review and update both geographic and treatment-related program in the treating of aquatic infestations of Eurasian Watermilfoil Myriophyllum spicatum and advancement of the state of the science of aquatic plant management. The purpose of the APMP is to prevent the spread of watermilfoil and to alleviate negative consequences of thick growth of the plant, such as diminished accessibility and desirability of water bodies for public recreational use, increased public costs for cleaning accumulations of plant material at dams, obstruction of drainage, restriction of natural water flows, reduced navigability, and damages to fishes and wildlife habitats. Methods for decreasing the spread of watermilfoil include mechanical harvesting and handpulling, bottom tillage or rotovation bottom barriers, suction dredging, chemicals such as fluridon or endothall, biological control methods herbivorous fish and insects, pathogenic microorganisms, and competitive plants, and integrated control methods using two or more of the above methods.
