South Twin Lake having about 3,200 acres (13 km2) is wholly within Penobscot County, Maine. It is about 6 miles (10 km) west of Millinocket, Maine and is part of the Pemadumcook Chain of Lakes. The lake is centered at 45°37.25′N 68°51′W / 45.62083°N 68.850°W and has spillway elevation 492 feet (150 m) above sea level. It is part of the watershed of the West Branch of the Penobscot River.
There is a State-sponsored boat access ramp in Partridge Cove off Maine State Route 11 at 45°35′57″N 68°49′15″W / 45.59920°N 68.82070°W. Parallel to the east side of the lake is Route 11 and the tracks of the Montreal, Maine and Atlantic Railway. The north south extent of the lake is about 1.8 miles (3 km) at the east end due to the extent of Partridge Cove at the southeast corner of the lake and the same at the west end due to Lincoln Cove at the northwest end. The average width of the lake appears to be 1.25 miles (2 km) roughly north to south and about 4 miles (6 km) long in a WNW direction. A gravel-surfaced road called Turkey Tail services the south side camps and connects to Route 11 at Partridge Cove. The lake has several rocks which are navigation hazards and in the spring of the year, one should be on the lookout for drifting logs.
