EWM Chemical Treatments to take place between the end of May and early June
As many of you know, the North Woods has experienced a relatively late spring this year. Our ice out date was a full month later than last year and, as a result, much of the spring time activity around the lake has been pushed back.
As in the past several years, the Tomahawk Lake Association will address the Eurasian Water Milfoil (EWM) infestation in the lake, using the two-tiered approach of chemically treating areas of larger EWM infestation and manually removing smaller and new sites of EWM with our innovative Hydraulic Conveyor System. We have mailed a notice concerning our intent to treat to shoreline owners with properties in close proximity to treatment sites. In addition, we wanted to alert the entire TLA member base.
Our chemical treatments are made using a very low dosage of the aquatic herbicide 2,4-D. This herbicide has been used for a number of decades. It has been shown to be a very safe chemical herbicide that dissipates in concentration to virtually nothing within the first 24-48 hours (dependant upon factors such as current and wind action). It should be noted that 2,4-D is not harmful to grass, however property owners are asked to turn off sprinkler systems that draw from the lake during our treatment time to avoid removing the 2,4-D from the lake until it has a chance to work on the EWM.
We are currently monitoring water temperatures weekly to make sure that we schedule the treatments at times when the optimal water temperature has been achieved. Our intent of course is to maximize the treatment effectiveness.
We are anticipating that our chemical application will be made during the last week in May, or possibly in the first week of June, dependant upon water temperatures.
When the final treatment dates have been finalized, we will alert you via email.
If you have any questions, please feel free to call TLA Executive Director, Ned Greedy at (715) 358-7896.
