Description
Althea Lake is a 43-acre warm water lake that drains into Mascuppic Lake to the north and lies one mile east of Rt. 113 and the Merrimac River in Tyngsborough. Althea Lake has an average depth of 5 feet, a maximum depth of 16 feet and aquatic vegetation is common often encompassing most of the shallows forming a ring around the pond. Large portions of the shoreline are marshland which limits development to a small portion of the southern shore.
