Aquatic Control, Inc. will be spray-treating areas of Lake Shafer for Eurasian Milfoil tomorrow, September 4th, starting at 7 a.m. They will have two boats going – one boat will be starting upstream and one boat in the southern treatment zones – both working their way back to the launch at Big Monon Camp. It is recommended to limit boat traffic in the treated areas and to turn off lake-drawn irrigation systems for 3 days.
