[1] The river is in the Mosso-Malagarazi depression, which has forest galleries in wooded fringes along the watercourses.

[8] The Kayogoro Marshes are in the valley of the Buga Colline between the Kirombwe River, a tributary of the Mutsindozi, and the Malagarazi.

The water of these rivers rises in the rainy season after October and floods the whole valley.

When the water recedes in May, crops of rice, sweet potatoes, corn, peanuts, beans, onions and vegetables are grown in the marsh.

[9] The Mutsindozi River supplies water to the Moso sugar project in Rutana Province, which was included in Burundi's third five-year economic and social development plan in the early 1970s, but began construction in 1986.
