Mono River

Along the southern portion of the river towards its mouth, it forms the international boundary between Togo and Benin.

Most of the river's basin on the upper tableland is cultivated for maize, yams, rice, cotton and cassava.

Studies have reported economic benefits from the dam, including tourism and fishing in the lake behind it.

Below this, the river becomes slow-moving and flows over a swampy floodplain, and there is a large area of contiguous wetland in both Togo and Benin.

This area has a rich growth of reeds, sedges and grasses, and manatees, crocodiles and hippopotamus occur in the river.
