Why is there a swimming warning for Cazenovia Lake next week?

Eurasian watermilfoil

Starting next Tuesday, June 10, the Town of Cazenovia will spray an aquatic herbicide on Cazenovia Lake. The pesticide application is set to begin Tuesday and may extend through Saturday June 14.

The application of the pesticide is designed to control the aquatic plant species, Eurasian watermilfoil. The pesticide to be used is called triclopyr which is sold under the brand name Renovate. Milfoil forms very dense mats of vegetation on the surface of the water. These mats interfere with recreational activities such as swimming, fishing, water skiing, and boating.

The Town announced it will spread the pesticide on the nearshore area, focusing on areas along the eastern and western shorelines. The warning label on the pesticide includes the recommendation that there be no swimming for three hours after the treatment. Click here to read the notice issued to neighbors in Cazenovia.
