The Ankobra River is situated in southwest Ghana. Starting north east of Wiawso, it flows about 190 kilometres (120 mi) south to the Gulf of Guinea, and enters the ocean about 60 km to the west of the city of Takoradi.[1] Near its mouth are the remains of Fort Elize Carthago, a Dutch trading post abandoned in 1711.

The Ankobra River is fed by the Nini River. Small ships can navigate 80 kilometres (40 nmi; 50 mi) inland, whilst the upper reaches contain rapids. Several hydro electric schemes have been proposed for the upper reaches.[1]

In 2003, mercury and arsenic were reported in the gold mining area of the Ankobra River Basin.[2][3]
