Although it is generally associated with Egypt, only 22% of the Nile’s course runs through Egypt. It originates in Burundi , south of the equator, and flows northward through northeastern Africa, eventually flowing through Egypt and finally draining into the Mediterranean Sea. The River Nile is formed from the White Nile, which originates at Lake Victoria and the Blue Nile, which originates at Lake Tana in Ethiopia. These rivers meet in Sudan and then go on their long journey northwards towards the sea. The White Nile is a lot bigger than the Blue Nile, but because of losses along the way the it only contributes about 15% to the flow of the combined Nile. The Blue Nile, rising in Ethiopia, contributes about 85% to the flow of the Nile that passes through Egypt to the Mediterranean

It should be noted that Nile is not much longer than Amazon which is approximately 4,000 miles (6,400 km) long. However Amazon is the biggest river in the world, measured by the amount of water that flows down it, accounting for nearly one-fifth of the world’s total river flow.


The source of the Nile is sometimes considered to be Lake Victoria, but the lake has feeder rivers of considerable size. The Kagera River, which flows into Lake Victoria near the Tanzanian town of Bukoba, is the longest feeder, although sources do not agree on which is the longest tributary of the Kagera and hence the most distant source of the Nile itself. It is either the Ruvyironza, which emerges in Bururi Province, Burundi, or the Nyabarongo, which flows from Nyungwe Forest in Rwanda. The two feeder rivers meet near Rusumo Falls on the Rwanda-Tanzania border.
