Stop Invasive Aquatic Plants

Protecting Great and Long Ponds since 1908 — and still just as dedicated in 2025.

Invasive aquatic plants like Variable Leaf Milfoil threaten Maine’s waters. They choke out native species, disrupt ecosystems, and impact recreation. The Belgrade Lakes Association has been on the invasive frontlines since 2012 — and we need your help to continue the fight.
