The river separates different groups of the Budu people of Wamba Territory, who speak different dialects on the western Ibambi side of the river and on the eastern Wamba side, although they consider themselves one people.

[3] Its southern tributaries include the Uala, Afande, Mambo and Ngaue rivers.

The partly rocky banks, over thirty feet high, stood back to form flat margins fifty to sixty feet wide which were flooded at high water.

[5] In the colonial era a car ferry operated across the river, although not always during high or low water.

It consisted of a number of dugout canoes lashed together sideways and covered with a wooden platform, and was pulled across the river by a cable.
