Malagarasi

The Malagarasi River is one of the Longest Rivers in Tanzania, flows through Kigoma Region in western Tanzania, with one of its tributaries coming from southeastern Burundi. The river also serves as the western boundary of Tabora Region, the southern boundary of Kagera (region), and the southwestern boundary of Geita Region. It is Tanzania's second-longest river, after the Rufiji—Great Ruaha, and has the biggest watershed of any river that flows into Lake Tanganyika. The Malagarasi-Muyovozi Wetlands have Ramsar status. The Malagarasi has been dubbed "the river of wicked spirits" by local tribes.

The river's headwaters are near the Tanzania-Burundi border. The river's first 80 kilometers (50 miles) mark the international border between Tanzania and Burundi. Several tributaries from the highlands of Burundi join its right bank. The Malagarasi River enters Tanzania at its confluence with the Lumpungu River, forms around, and discharges into the eastern shore of Lake Tanganyika about 25 miles (40 km) south of Kigoma, near Ilagala. It is a major inflow into the lake. The main tributary is the Moyowosi River, which flows into the Nikongo River; additional tributaries include the Ugalla River, Gombe River, Ruchugi River, Lumpungu River, and Nguya River. It is classified as a low-stream river, having four biotopes in its drainage: marshy regions, river channels, a flowing river with a few mild rapids, and a big double-branched delta.
