Management of Eurasian Watermilfoil in Houghton Lake, Michigan: Workshop Summary
Abstract
Houghton Lake is the largest inland water body in Michigan, and as such, is a major ecological and recreational resource for the region. Results of a survey conducted in October 1999 indicated that over 4,000 ha of the lake had become infested with the exotic submersed plant Eurasian watermilfoil (Myriophyllum spicatum L.). Local concern regarding the problems associated with the Eurasian watermilfoil infestation centered on its future impact on recreational opportunities, fish and wildlife resources, and ecological health of the lake. In 2001, the U.S. Army Engineer District, Detroit, was tasked by Congress to assist the Houghton Lake Improvement Board (HLIB) in the development of a draft plan for managing Eurasian watermilfoil on the lake. Therefore, a workshop was held to review operationally viable techniques for managing Eurasian watermilfoil in Houghton Lake, and discuss environmentally sound options for managing this invasive plant. Management options considered included the use of chemical herbicides currently registered in the state of Michigan; the use of the milfoil weevil, a biocontrol agent; the use of mechanical harvesters; and an integration of these techniques. In addition, impacts to water quality and fish and wildlife resources were considered. The objective of this report is to summarize and present information from the workshop and other sources that will provide guidance for the environmentally sound management of Eurasian watermilfoil in Houghton Lake.
