Description

Variable milfoil is our primary concern at Lake Massasecum.  These growths cannot be removed unless they are located and marked. Please learn to recognize this plant by looking at available pictures, going on the internet, etc. Massasecum is the only lake in NH which can boast of having Sclerolepis (pictured below) in its native aquatic plant community. Bladderwort and Waterweed (pictured below) are also very common. Sclerolepis makes up the bulk of the floating “seaweed” throughout the lake and can be confused with milfoil by inexperienced observers. Once clearly identified, milfoil can easily be distinguished from the “good” plants pictured below. If you see what you believe to be milfoil please notify a Lake Host at the boat ramp, campground staff or Dave Gaudes at the email address provided above.is a submerged aquatic plant that has densely packed whorled leaves. It is usually found along the shorelines of lakes and ponds. Variable milfoil can grow in depths of up to 10-12 feet, forming dense mats near the surface of the water. The plant produces a spike-like flower that grows above the water’s surface from mid to late summer.
