The earthen dam that makes up Mallet Pond is about 30 feet high. You wouldn't know it unless you look at it from a top the dam.
Mallet Pond State Forest is 2,567 acres of state land north of Burnt Rossman State Forest, outside of Fultonham. There are several informal campsites along the lakes that are popular during the summer months. Mallet Pond is most commonly fished for its trout. Special regulations apply. Some decent sized trout have been taken from this small pond. The pond is stocked annually with approximately 250 brown trout and 250 rainbow trout from 8-10" in length. Parking area at gated road off Rosseman Fly Road. Roughly a 0.3 mile walk from parking area to pond.
