Grafton Pond is located within the Society for the Protection of New Hampshire Forests' Grafton Pond Reservation and is an active common loon nesting site. There is a cement dam with a spillway for the pond leading into Bicknell Brook. It is a local favorite for swimming, fishing and boating, although only electric engines are allowed on the pond. No camping or campfires are allowed around the pond or on any of the islands, and it is a "carry in, carry out" area.

The lake is classified as a warmwater fishery, with observed species including smallmouth bass, chain pickerel, yellow perch, sunfish, and brown bullhead,^[1] as well as largemouth bass.
