The two main rivers that divide the country cire the Niger eind Benue. The Kaduna Sokoto and Ogun rivers similarly drain the land and facilitate agriculture.

The hydrology of Nigeria is dominated by two great river systems, the Niger and Benue, and also the third, the Chad systems. With the exception of a few rivers that empty directly into the Atlantic Ocean, most others flow ultimately into either of the two major systems only a few flow into the Lake Chad in the northeastern part of the country. The Niger and Benue rivers are separated by a primary watershed extending northeast and northwest from the Jos Plateau, which is the main source of their principal tributaries. Northwest of the Plateau lies the elevated, drift covered plains of central Hausa-land, which is drained by numerous streams, all flowing outwards to join the major tributaries.

We know that, about 3000-5000 years ago, the inland delta was finally emptied by capture to the benefit of an west-east flowing river tributary. This river tributary bears the name of the river, having created the inland delta, and, as a questionable feeder of the Senegal basin, has become the upper branch of the present Niger.
