WORCESTER - Treatment of Coes Pond for an invasive aquatic plant will take place on Friday, June 18.
The Worcester Department of Public Works and Parks [DPW] advises residents to stay out of the water, discontinue boating and fishing, and keep pets out of the water during the day on Friday.
DPW also recommends discontinuing use of water from Coes Pond for irrigation of plants or lawns or for watering livestock for five days after the day of treatment, until Thursday, June 24.
DPW contracted for treatment of Coes Pond with the herbicides imazamox and diquat dibromide, known as Clearcast and Reward.
DPW says the treatment is a safe and effective method to control the growth of the invasive aquatic plants Trapa natans (Water Chestnut) and Myriophyllum spicatum (Eurasian milfoil). It is a common practice to reduce invasive weed density that poses no risk to humans or animals after application is complete, though water use for irrigation is discouraged.
The application is coordinated with the Tatnuck Brook Watershed Association and has been approved by the Worcester Conservation Commission.
