MEMPHREMAGOG, Lake, a body of water, about 35 m. long from N. to S. and from 2 to 5 m. wide, situated partly in Vermont and partly in Quebec, Canada. It discharges through Magog river into the St. Francis, and thence into the St. Lawrence. The surrounding scenery is picturesque. Along the W. shore are several mountains, prominent among which are Owl's Head, Elephantis, and the Sugar Loaf; the E. shore presents a pleasing contrast. The lake is studded with islands, and abounds in fine fish. Near its head is the village of Newport, and at its outlet Magog, between which a steamer plies in summer, accommodating the numerous visitors.
