This design memorandum recommends a plan for the control of Eurasian watermilfoil, a nonnative aquatic plant, in the waters of Washington State. The plan was developed in response to a request from the State of Washington. Milfoil is presently a problem in several lakes, rivers, and reservoirs in eastern Washington and the Puget Sound area in western Washington. It has curtailed recreation activities in these areas and has the potential of decreasing water quality and impacting hydropower production, fish and wildlife, irrigated agriculture, and public health. In 1978, there were approximately 1,500 acres of navigable and nonnavigable waters with milfoil growth throughout the state. It is estimated that 113,000 acres of navigable waters could become infested within the next 15 years. The recommended plan consists of methods of prevention and control outlined in the report.
