Oti River

The Oti River, also known as the Pendjari River, is a West African international river. It begins in Benin, flows through Togo, and eventually joins the Volta River in Ghana.

The Oti River is approximately 520 kilometers (323 miles) long. Its headwaters are in Benin and Burkina Faso, and it flows through Benin, Togo, and Ghana before joining the Volta River. Togo's left bank tributaries flow from the Togo Mountains to the south. The Kara River is one of its eastern tributaries, with its confluence on the Ghana–Togo border, where another tributary, the Koumongou River, joins from the south. The Oti River's mouth was once on the Volta River, but it now flows into Ghana's Lake Volta reservoir.

The river runs through the northern part of Togo in a savannah-clad valley 40 to 50 kilometers (25 to 31 miles) wide. Gallery forest grows along the river's banks and floods on a regular basis. The hot, dry Harmattan wind blows from the north during the dry season, which lasts from about November to April. The river's flow is low at this time of year. Both the Oti and the Koumongou rivers have floodplains that are 10 and 4 kilometers (6.2 and 2.5 miles) wide, respectively. During the wet season, these flood extensively, but during the dry season, they become dry, dusty plains with the occasional pond or lake in a depression. During the dry season, cattle graze on the floodplains. There is also some small-scale crop growing and hunting of game.
