White Nile
Headwaters

The Kagera River, which flows into Lake Victoria near the Tanzanian town of Bukoba, is the longest feeder river for Lake Victoria, although sources do not agree on which is the longest tributary of the Kagera, and hence the most distant source of the Nile. The source of the Nile can be considered to be either the Ruvyironza, which emerges in Bururi Province, Burundi (near Bukirasaz), or the Nyabarongo, which flows from Nyungwe Forest in Rwanda.

These two feeder rivers meet near Rusumo Falls on the border between Rwanda and Tanzania. These waterfalls are known for an event on 28–29 April 1994, when 250,000 Rwandans crossed the bridge at Rusumo Falls into Ngara, Tanzania, in 24 hours, in what the United Nations High Commissioner for Refugees called "the largest and fastest refugee exodus in modern times". The Kagera forms part of the Rwanda–Tanzania and Tanzania–Uganda borders before flowing into Lake Victoria.
