Monponsett Pond, also called Monponsett Lake and the Twin Lakes, originally one lake is dissected by route 58 into a system of two ponds, West and East, mostly in Halifax, Massachusetts, with a small portion of West Monponsett Pond extending into Hanson.

Water diversions from Monponsett into Silver lake are not permitted during the summer months from June 1 - September 30.

A paved boat launching ramp to West Monponsett Pond is on this highway north of White Island Road.

White Island in the center of the pond is known to have been the fishing camp of Wamsutta, brother of Chief Metacomet (also known as King Philip).

Route 106 runs close to the southern shore of East Monponsett Pond, and Route 36 abuts the southeast corner of East Monponsett Pond, where there is a paved launching ramp.
