Nguera
Nguera lies near the Lualaba, the upper course of the Congo, northwest of Nyangwe. Between Kibombo and Kindu, rapids interrupt the river's navigable stretches; below them, the Lualaba broadens as the Elila and Ulindi bring water from the eastern highlands. Wagenya fishing communities along this part of the river controlled traffic on the Lualaba, using their knowledge of its waters to move people and goods.
