Lake Togo is about 15 km (9.3 mi) long, 6 km (3.7 mi) wide and 64 km² in area. It receives water from the Sio River in the southwest and various other smaller streams to the west and east and the Haho River enters from the north. The lake is separated from the sea by a sandbar a kilometre or so wide. Water exits to the east through a canal-like extension where it receives water from the nearby, smaller Lake Vogan, and continues into the lagoonal system along the coast.[3]
A main road traverses the coast to the south of the lake and local roads circle the lake, connecting the small villages. The area is not heavily populated and there is little tourism. The economy depends on extensive agriculture and fishing, with seine nets being used and fish sold in local towns. Coconuts are grown between the lake and the coast, and there are plantations of coconut and oil palms on the flood plains to the north of the lake.[3]
