The Kanyosha River rises in central Bujumbura Rural Province and flows west past Buhonga to enter the south of Bujumbura Mairie Province, where it flows through the Commune of Muha and Commune of Kanyosha to its mouth on Lake Tanganyika.

However, given lack of funding and the risk of floods, the agency soon allowed the cooperatives that did manual dredging to resume work.

The cooperatives would pay OBUHA for the construction materials they retrieved, and were committed to building dikes and planting trees to protect the river banks.

On the question of extraction of building materials, he noted that cooperatives engaged in this work were signing contracts with OBUHA and paying taxes that would help fund repair of the ravines.
