Lake Improvement Board
Formed in July 2005, the Eight Point Lake Improvement Board is chartered by Clare County and Garfield Township to oversee lake water quality and treatment needs to counteract the spread of aquatic invasive plants. The Board members are determined by Michigan law and include the Clare County Drain Commissioner, County Commissioner, 2 representatives from Garfield Township, and one lake riparian. The Board is responsible for determining tax special assessments on properties having dedicated lake access to pay for the costs associated with treating the lake. The Board hires consultants and treatment contractors as needed to perform surveys and to treat the lake. Currently, the L.I.B. is focused on treating Eurasian Watermilfoil in the lake.

Lake Treatment for Eurasian Watermilfoil
Each year, the initial treatment for Eurasian Watermilfoil takes place during the latter part of June, following a plant growth survey to determine the planned treatment map (once the water temperature is sufficient). Notices are posted at all waterfront cottages. Lake treatment maps are available on thepage.
2012 treatment included 10,000 weevils stocked at 2 sites
For a number of years beginning in the late 1980s, the Eight Point Lake Property Owners Corporation initiated a limited water quality testing program in conjunction with the Central Michigan Marine Biology Department. In 2008 that program was resurrected and expanded by the Eight Point Lake Improvement Board. The Board hires a Marine Consultant to collect and test water samples from 5 locations on the lake each spring. The samples are processed through nearly a dozen tests to measure such things as clarity, alkalinity, and nitrate and phosphorus levels.
Results thus far indicate the overall water quality of Eight Point Lake is excellent, far exceeding the accepted norms for Michigan inland lakes. There have been no indications of pollutants or major problems.
There has, however, been a steady increase in the levels of nitrates and phosphorus in the lake to increase, which is generally associated with increased levels of decaying plant life in the lake and the runoff of fertilizers used on plants and lawns. Property owners are urged to avoid raking leaves or other yard debris into the lake and to avoid the use of granular commercial fertilizers anywhere near the lake.

EIGHT POINT LAKE 2014 LAKE IMPROVEMENT BOARD REPORT
The LIB (Lake Improvement Board) was created in 2005 to assess property owners for overall lake management and the treatment of invasive weeds because the Property Owners' Association was no longer able to generate enough voluntary donations to deal with the management and treatment of the lake.
All the chemical treatments have been done with professionally applied, DNR- approved herbicides. In 2012 a new program was launched which entailed the use of native water weevils to eat up the milfoil. The goal was to evolve to an environment where colonies of these tiny and totally natural weevils would keep the Eurasian Milfoil in check so we don’t have to use several tons of herbicides each year.
In 2014 we were forced to discontinue the weevil stocking program because extensive spring underwater surveys by divers were unable to find any breeding colonies of the weevils. It appears that two very cold winters in a row and the fact that Eight Point is largely surrounded by seawalls, which makes it very difficult for the weevils to leave the water and burrow into the soil, have wiped out the thousands of weevils planted over the past 2 years.
The disappointing results with the weevil program left us with no choice but to return to the use of herbicides to treat the Eurasian Milfoil. Just under 40 acres were treated during the months of June and August, which is consistent with our annual average of 41 acres. A map of those locations is posted on the Association website.
