The town announced this week that it will conduct herbicide treatments at Lake Maspenock to control “nuisance aquatic vegetation” on Tuesday.

During and following treatment, residents are advised not to use the lake for recreation or agricultural purposes for a short period of time. Boating, fishing, swimming and watering of livestock are not advised until Thursday. The town cautions against using the lake for irrigation until June 22.

The Conservation Commission in April approved a limited application of herbicides in the lake this year. SOLitude Lake Management will perform the application, focusing on about 50 acres in the north basin as well as the cove by the boat ramp and the area south of Sandy Beach.

Herbicides recommended for use include Tribune (diquat dibromide), ProcellaCor (florpyrauxifen-benzyl) and flumioxazin. The chemicals are intended to address invasive aquatic plants found in the lake such as Eurasian milfoil, variable milfoil, fanwort, bladderwort and pondweed.
