The Niger river has a peculiar flow. Having its source only 250 kilometres from the Atlantic Ocean in Guinea, the river flows northeastwards through Mali. It then makes a turn to the southeast and flows through Niger, Benin, and Nigeria into the Gulf of Guinea. This image shows - in green - the Inner Niger Delta, which is a bifurcation of the Niger and one of its tributaries, the Bani river. The triangular shape in the upper part of the image is Lac Fabuigine.
