Oti in Depth
Geography
The Oti River is about 520 km (323 mi) long. Its headwaters are in Benin and Burkina Faso, it flows through Benin and Togo and joins the Volta River in Ghana. Tributaries on the left bank in Togo originate from the Togo Mountains to the south. One of its eastern tributaries is the Kara River, the confluence being on the Ghana–Togo border, where another tributary, the Koumongou River, joins from the south. The mouth of the Oti was formerly on the Volta River, but it now flows into Lake Volta reservoir in Ghana.
The river crosses the northern part of Togo in a savannah-clad valley some 40 or 50 km (25 or 31 mi) wide. Along the margins of the river is gallery forest which floods periodically.
Hydrology and Seasonal Flow
The river is highly seasonal, with peak discharge occurring during the rainy season and very low flow during the dry Harmattan period.
This seasonal variability causes periodic flooding of surrounding floodplains, especially in Togo and northern Ghana.
Ecology and Environment
The Oti River basin includes savannah ecosystems, floodplains, and gallery forests that support seasonal agriculture and pastoralism.
Floodplains along the river are used for grazing and cultivation during dry periods when water levels recede.
