Androscoggin Lake Under Attack of Invasive Milfoil – July 2022

July 15, 2022

Since mid-May, our staff have been working hard on Androscoggin Lake to manage the invasive variable milfoil infestation discovered in the north end of the lake in the fall of 2020. Unfortunately, early this season we found that the infestation had spread beyond the area currently closed to all boat traffic, and plants had regrown in areas where we had removed them last year.

Every week, our staff spend 25-40 hours surveying the infested area and marking each mifloil plant. Once a week, a trained SCUBA diver works with us to carefully remove the plants, including all the roots, by hand. We partner closely with the Maine DEP, ensuring that we are taking every measure possible to fight the infestation.
