Water Quality | To study and monitor water quality and level and to observe and report problems of pollution, soil and bank erosion, etc.

Weed Management | In conjunction with the Township, organize and administer the effort to locate and control noxious exotic weed infestations. Maintain awareness of and advise Board of management alternatives. Organize and oversee control activities.


The Lake Management-Treatment Committee and our key lake management partners met on April 12, 2021. The purpose of the meeting was to analyze the drone mapping pictures following the 2020 applications, evaluate the success of the two treatments and plan for the 2021 season. Zero Gravity (the drone company) presented us with data to help plan for 2021. Clear Water Lake Management (our product applicator) was also at the meeting to help us interpret the information and do planning for 2021. In 2020, approximately 12 acres were treated. This represents only 0.4% of the total surface area of Long, Ruth, and Mickey lakes combined.

Our plan is to continue to treat the aquatic invasive species Eurasian Watermilfoil twice each year to improve the quality of the lakes for boating, etc. using advanced technology to precisely target the treatment to where it is needed. The 2021 plan is to treat approximately the same total area as in 2020 (e.g. 12 acres), There are some areas that were treated in 2020 that will not require treatment this year. Many of the areas that contained the aquatic invasive species Eurasian Watermilfoil (EWM) are growing native plants now that the Eurasian Watermilfoil is gone. There are some areas that were treated successfully in past years, but now the Eurasian Watermilfoil has returned that will require treatment in 2021. These are among the areas that will be treated on Tuesday, June 22, 2021, and Tuesday, July 20, 2021. The rain date will be the next day, if necessary.

The activities of the Lake Management Committee on all three lakes are totally funded by the Long Lake Association and our local partners. Your membership dues are an important part of our funding to control the levels of Eurasian Watermilfoil to protect our lake from this very aggressive aquatic invasive species. If you wish to provide further financial support for this program, the Long Lake Foundation has created the “LLF Invasive Species Defense Fund” to further study and remediate both aquatic and terrestrial invasive species in and around Long, Mickey, and Ruth Lakes. Your tax-deductible donation under the 501c3 designation of the IRS code to this critical fund will ensure the effective management and the health of our lakes far into the future. Please visit the LLF website at to learn about the Long Lake Foundation and to donate online or mail a check to “Long Lake Foundation” to

P. O. Box 31; Interlochen, MI 49643 and put “LLF Invasive Species Defense Fund” in the memo area.


It is the policy of the Long Lake Association to continue utilizing an integrated pest management program in order to minimize the impact of invasive species on the ecological health and recreational enjoyment of the lakes.  We will continue to closely monitor all conditions with the understanding that with most invasive species of plants and animals, complete eradication is unlikely.


The treatment map identifies the Eurasian Watermilfoil treatment areas plan for 2019.  The treatment includes herbicide (Navigate Pellets or Navitrol Liquid) on Long, Mickey and Ruth Lakes, totaling approximately 10 acres. Our goal remains to be environmentally responsible while monitoring and controlling invasive species in our lakes.  For more information on our lake management program or to provide feedback, please contact Brent Schnell or Dave Baker.


​On Long Lake we occasionally see mounds of foam and suspect detergent discharge from homeowners.  Actually it is naturally occurring Bio-foam and not detergent.  When algae, plant, and fish material break down organic compounds are released.  Some of these are surfactants which change the surface tension (attraction between water molecules) of the water and allow wind and waves to introduce air producing Bio-foam.  This foam is long lasting unlike detergent foam and often has a brown tinge due to the tannins in the water.
