It has a smaller tributary river, the Oti, which enters Ghana from Togo in the east. The Volta River has been dammed at Akosombo for the purpose of generating hydroelectricity. The reservoir named Lake Volta stretches from Akosombo in the south to the northern part of the country, thus being one of the largest man-made reservoirs in the world.
