The Kayave River (French: Rivière Kayave) is a river in Burundi, a right tributary of the Akanyaru River.
The Kayave River rises in the northwest of Kayanza Province, not far from the head of the Ruvubu River, fed by streams from the Kibira National Park. It flows east to the border with Ngozi Province, and runs along the border for some distance before turning north and running through Ngozi Province to its mouth on the Akanyaru River.[3]
Tributaries
The Kayave River forms where the Ngute meets the larger Nyakimonyi and flows east, receiving the Nyabikenke, Jembegeti, Kironge from the right (south), the Nyarusasa from the left (north) and the Nkingu from the right. It turns to the north, and receives the Gitabo and Rushahuriro from the right (east), the Nkamwa and Kirimwe from the left (west) and the Rwintaro from the right just before entering the Kanyaru.[4]
