Eurasian watermilfoil has shown aggressive growth in several areas of the lake this summer. To help keep it under control, an additional treatment is planned for the end of July.

Please see the attached map for the areas scheduled to be treated.

A placard will also be posted in lakeside yards the day before treatment with the specific herbicide being used and all applicable restrictions.

​

Important restrictions:

🏊 Swimming: Avoid swimming in treated areas for 1 day.

💧 Irrigation: Do not use lake water for lawn or landscape irrigation for 5 days after treatment.

 

Thank you for your cooperation as we continue working to protect the health and long-term quality of Upper Straits Lake.
