Ripon Falls may be the starting-point of the River Nile, but the many streams that flow into Lake Victoria could claim to be the true source.
Much of Lake Victoria is surrounded by mountains with streams tumbling down into the lake. The largest tributary of Lake Victoria is the Kagera river. The Kagera and its tributary the Ruvubu, with its headwaters in Burundi, is now considered to be the true source of the Nile. It is from here that the Nile is measured as the world's longet river.
