Course
The Rwaba River forms in the northwest of Makamba Province to the north of Murinda and flows south, then southwest to enter Lake Tanganyika just north of Nyanza Lac.[1] The Rwaba River drains the sedimentary plain of Nyanza-Lac, which is about 16 kilometres (9.9 mi) wide and backed by high ground.[2] Open forests on the steep slopes around the plain form a natural water catchment system, and prevent sedimentation of the river and damage from landslides.[3] The river is fed by springs on the slopes or at the foot of the slopes.[4]
