At the July 8 Heritage Commission meeting, the board began deliberating on a proposal for milfoil treatment that could have significant implications for our lake and its residents.
The proposal involves treating 39 acres of the lake, which represents an increase in treated acreage and higher chemical application rates compared to previous years. Furthermore, the current plan does not include the use of a weighting agent, a component that was utilized during the 2015 treatment process.
Because of these changes, the board has not yet reached a decision. Commissioner Dennis Bothamley voiced the need for much more information and additional discussions with all involved parties before the commission moves forward. This caution is critical, as the decision directly affects lake users, property owners, and the local environment.
