Lake Margrethe was treated for Eurasian milfoil and other invasive plants on Thursday, August
13th by the Professional Lake Management Company of Howard City, Michigan. Our lake has not been fully treated since 2016 and milfoil growth has spread dramatically in the last 4 years. This year’s treatment included a GPS survey to identify and locate as many milfoil beds as possible. Professional Lake Management located 51 acres which required treatment this year. The total bill for the 2020 invasive treatment was $35,433.63 and that bill is divided between the Lake Margrethe Special Assessment District (SAD), the Lake Margrethe Foundation, and the Michigan Department of Military and Veterans Affairs. Each of those sponsors will pay $11,811.21 to the Charter Township of Grayling, the supporting agency of the Lake Margrethe SAD. The treatment area of 51 acres, which included the Harbor Beach canal, is the largest area we have ever treated. Unfortunately, we will never totally eliminate Eurasian
milfoil and Lake Margrethe will require continuing treatments to control the growth and spread of this invasive plant. It is impossible to know what Lake Margrethe would look like now if we had failed to begin treatments in 2003.
