Use restrictions recommended for Lake St Catherine following milfoil treatment

first_imgThe application of the chemical herbicide triclopyr is scheduled for Lake St. Catherine on Monday, June 17 to control the aquatic invasive plant Eurasian Watermilfoil, Myriophyllum spicatum, in selectively chosen dense beds around the lakeshore. Local residents and recreational users have been informed of this planned herbicide application, authorized by the Department of Environmental Conservation’s Aquatic Nuisance Control Program. As a precautionary measure, under advice from the Vermont Department of Health, the public is strongly encouraged to avoid unnecessary exposure. Please follow the voluntary use restrictions for Lily Pond, Lake St. Catherine, Little Lake and the outlet stream to North Road: ·         No use of the water for any purpose during the day  of treatment and the following day (June 17 & 18)·         No use of the water for drinking, or for food and drink preparation until further notice·         No use of the water for recreation (swimming, boating, fishing) until the third day after treatment (June 19)·         Domestic uses, other than for drinking, or for food or drink preparation, may resume the third day after treatment (June 19)·         No use of water for irrigation until October 15 or until further notice Triclopyr is a highly effective broadleaf herbicide that is used to control Eurasian Watermilfoil. It is most effective when applied in the late spring while Eurasian Watermilfoil is growing. Eurasian Watermilfoil threatens the natural lake environment by severely reducing native plant diversity, which adversely affects aquatic habitat. Commonly found in shallow bays and along the shoreline, dense mats of Eurasian milfoil often render other recreational activity such as boating and swimming impossible. The displacement of native aquatic plants has been reported in lakes throughout Vermont where Eurasian Watermilfoil has become widespread and dense. Native plants are not significantly affected by this herbicide. The use of herbicide is an integral part of a lake-wide management plan, which includes manual and mechanical techniques, to control this invasive plant. Contact the Lake St. Catherine Association at 518-505-2195 or visit its webpage at www.lakestcatherine.org(link is external) for updates or further information. Visit Vermont’s Aquatic Nuisance Control Program webpage at: http://www.anr.state.vt.us/dec/waterq/permits/htm/pm_anc.htm(link is external) for more information about Eurasian Watermilfoil and other aquatic invasives in Vermont.last_img
