Rutshuru River

The Rutshuru River (French: Rivière Rutshuru) is a river in the eastern Democratic Republic of the Congo that drains Lake Mutanda in the foothills of the Virunga Mountains in Uganda, flowing northward into Lake Rutanzige (formerly Lake Edward). For most of its length it runs through the Rutshuru Territory in North Kivu province.

Course
The Rutshuru is considered the highest source of the Nile. Lake Bunyonyi, with a surface elevation of 1962 m, is fed by the Kabirita River from Rwanda and from many affluents from the surrounding hills, which rise to elevations of 2200 to 2478 m.

Lake Bunyoni drains into the Ruhuhuma Swamp at its northern end. The eastern part of this swamp drains into the upper course of the Ishasha River, while the western part drains to Lake Mutanda at a surface elevation of 1,800 m.

Lake Mutanda discharges from its south-west corner through the Kako River and the Tshengere Swamp into the Rutshuru.

At one time, what is now Lake Kivu was in the watershed of the Rutshuru River. Volcanic eruptions at the end of the Pliocene epoch created the Virunga Mountains, blocking off this part of the drainage basin. The water rose inside the basin to form Lake Kivu, eventually breaking through at the southern end to drain into Lake Tanganyika.

In its lower reaches, the river flows through the central section of the Virunga National Park.

The Rutshuru, Rwindi and Ishasha rivers form swamps and grasslands to the south of Lake Rutanzige.

The river is home to herds of hippopotami. As of 2007, there were about 115 hippopotami per kilometer of the savannah and grass steppe along the Rutshuru River.

There has been discussion about damming the river, which would have a serious impact on the downstream riverine wetlands.
