Smelt Pond is a 44-acre (180,000 m2) pond in Kingston, Massachusetts. The pond is located west of the Kingston Collection and north of U.S. Route 44. Camp Nekon, a 193-acre (0.78 km2) former Girl Scout camp which closed in 1975 and has since become a recreation area, surrounds the pond. The water quality is impaired due to non-native aquatic plants and non-native fish in the pond.
