WORCESTER – The City of Worcester advises residents to discontinue using water from Lake Quinsigamond for irrigation of plant and lawns or watering livestock on Wednesday, Aug. 23. Boating between the narrows at King’s Point and Gauch Park are also discouraged on the same day.
The city’s advisory is due to the contracting for the application of the herbicide florpyrauxifen-benzyl (trade name ProcellaCOR) to the lake on Wednesday.
The water will be open for all uses again on Thursday, Aug. 24.
According to the city, herbicide treatments are a safe and effective method to control the growth of the invasive aquatic plants, Eurasian Milfoil, and Variable Leaf Milfoil. The application of herbicides is a common practice to reduce invasive weed density and poses no risk to humans and animals after application is complete, though water use for irrigation is discouraged. This application has been approved by the Conservation Commissions of Worcester, Shrewsbury, and Grafton.
