Belleau Lake is a 187 acre lake in a 5.82 square mile watershed in Wakefield, NH. It is an artificial lake formed by the damming of the Little Ossipee River headwater. It flows over a dam through Woodman Lake and into Balch Lake. Invasive milfoil is found in this lake, and there are considerable efforts in place to manage this aquatic plant.
