Katonga

The Kagera river travels through Burundi, Rwanda, Tanzania, and Uganda, for a total distance of 249 miles (400 kilometers). The river's source is Lake Rweru in Burundi, and it flows east, crossing the borders of Burundi and Rwanda, as well as Rwanda and Tanzania. The Kagera then joins the Ruvubu River and continues north, passing through Rwanda and Burundi before crossing into Uganda and reaching its mouth at Lake Victoria, where it is the largest intake of water into the lake. During the 1994 Rwandan Genocide, bodies were dumped into a river that eventually flowed into Lake Victoria in Uganda, posing a serious health threat to Ugandans.

During wet seasons, rising water levels in the swampy watershed cause some water to flow west from this location into the western section of the Katonga River, which feeds Lake George, although the majority of the flow still flows eastwards into Lake Victoria. Along its route to Lake George, the Katonga river is supplied by various tributaries west of its watershed.
