Weed Watcher Toolkit
Join a Growing Community of Newfound Weed Watchers
Weed Watchers protect Newfound Lake from invasive aquatic plants by surveying Newfound's near-shore area for signs of invasive plant growth. Weed Watching usually takes place once a month from late May through August. It is a great way to better understand the ecosystem of your favorite part of Newfound Lake and adds an interesting layer to any trip out on the water. Learning what to look for is key.

Can’t make it to one of our scheduled trainings but have a group of potential Weed Watchers? We will come to you and train your friends, family, or neighbors on what to look for right from your dock! This is a great way to get school groups, camps, and Homeowner Associations involved in protecting Newfound Lake.
