Long Pond is a 7 km2 lake within the towns of Lakeville and Freetown, in southeastern Massachusetts. It shares its waters with Assawompset Pond. These lakes provide a source of drinking water to the city of New Bedford, the largest city in southeastern Massachusetts. Long Pond is roughly 1.6 kmwide by 6.4 km miles long, and contains three islands within its boundaries. In 1894 Assawompset Pond was dammed, increasing the water depth of Long Pond (which is connected by a small river) by about 1.5 m.
