CLWA completes treatment of invasive Eurasian Watermilfoil

The CLWA began its long-delayed treatment of EWM in Crystal Lake on June 29 under the terms of the authorization provided by the Michigan Department of Environment, Great Lakes, and Energy in Aquatic Nuisance Control Permit No. ANC9805924. Despite unfavorable weather, almost all of the 7-plus acres of infestation were treated, including the most heavy growth on the east end of the lake. A second treatment took place on July 27, completing the program for this year. The second treatment area was only 6.5 acres, as apparently some of the smaller patches that had been identified and treated in June were already gone. The thicker infestations appeared to be in a weakened state. A month after the second treatment, effects were visible, consisting of significant mortality at the DNR launch site, everywhere on the east end, and at the Lobb Road secondary launch. The interspersed pond weed and water celery remained healthy. Further inspection will occur in another month. If you have questions, see FAQs about Eurasian watermilfoil.
