Wayland Town Crier 5/8/09: Natick residents appeal herbicide use at Lake Cochituate. A group of 180 residents appealed the Conservation Commission’s vote to let the state Department of Conservation and Recreation use herbicides in the Lake Cochituate’s Middle Pond to control invasive Eurasian milfoil. The appeal claims the application made by DCR and approved by the commission in April violates the state Wetlands Protection Act and does not contain enough detail about the planned work.
