- • COUNCIL MEETING � JAN 0 9 2006 �lTY OF ORO�I� Lake Minnetonka Conservation District (LMCD) Proposed 2006 Milfoil Demonstration Project Outline December, 2005 OBJECTIVES • Demonstrate effectiveness of herbicides to control Eurasian Watermilfoil (Milfoil) infestations in Lake Minnetonka. • Evaluate/compare how effective herbicides are when they are used to treat large areas. • This is a demonstration project, not a research project. • Determine the feasibility of using herbicide treatments to supplement the LMCD's harvesting program. • Determine the level of public support for future large-scale herbicide treatments to manage Milfoil. • Keep the focus on all �nvasive species, not just Milfoil. ORGANIZATIONAL RESPONSIBILITIES • LMCD: Lead organization: planning, contracting, communications, and financing. • LMA: Supporting organization: technical support, communications, and financing. • MN DNR: Supporting organization: technical lead, possible grant funtling, and possible post demo evaluations. • Army Corps of Engineers: Supporting organization; technical support and possible post demo evaluations. PROJECT HIGHLIGHTS • Areas selected for herbicide treatment have hatl historical heavy growth of Milfoil. • These areas will be treated with herbicides that have demonstrated season long management control, with minimal sitle effects, • The areas to be treated will be in excess of 150 feet from the shore, with homeowners encouraged to apply for a MN DNR permit within 150 feet from the shore for private treatments. • The LMCD will be the single point of contact with the media for this project. Possible media contacts include local cable stations, local newspapers, the 14 LMCD member cities, etc. THREE AREAS TO BE TREATED (See attached schematic sheets for further details) Site#1- Phelps Bay • A 6.3 acre site is proposed to be chemically treated in the northwest end of Phelps Bay. • The herbicide triclopyr is proposed, with a treatment date of mid to late May. • No mechanical harvesting by the LMCD is planned for this site in 2006. Site#2- Carrnans Bay • A 13.2 acre site is proposed to be chemically treated in the north end of Carmans Bay, • A combination of 2,4-D antl endothall herbicides are proposed, with a treatment tlate of late April or early May. • A 2,0 acre site is proposed for control purposes in 2006, with no herbicide treatment plannetl for this area. • No mechanical harvesting by the LMCD is planned for either site in 2006. Site#3- Grays Bay • A 11,3 acre site is proposed to be chemically treated in the east side of Grays Bay. • The herbicide 2,4-D is proposed, with a treatment tlate of mid to late May. • No mechanical harvesting by the LMCD is planned for this site in 2006,
