The principal feeders of Lake Victoria are the following streams:--
on the north (1) Lukos or Yala, (2) the Nzoia 250 kilometres long, (3) the Sio. on the east (1) the Nyando, (2) the Inyayo, (3) the Gori, (4) the Mara Dabash, (5) the Rawana. on the south (1) the Symiya, (2) the Moame. on the west (1) the Lohungati, (2) the Kagera, with its branches the Nyavarongo, the Akanyaru and the Ruvuvu, with a maximum length of 600 kilometres and a discharge varying between 140 and some 600 cubic metres per second. (3) the Ruizi with a length of 280 kilometres traversing much marshy ground in its course. and (4) the Katonga 250 kilometres long.
The northern and western feeders are generally perennial streams, while many of the southern and eastern are torrents.
10. =The Victoria Nile.=--From the Ripon Falls to Lake Albert, the Victoria Nile has a length of 400 kilometres. The first 64 kilometres are down a steep slope, in a stream varying from 300 to 500 metres in width. Any project for a regulator at the Ripon Falls should contemplate development of electricity for working a railway along these 64 kilometres. The next 237 kilometres are through a flat marshy land, partly lake, partly swamps, but with the water never more than 4 to 6 metres deep. In this reach the Nile is navigable. This many-armed swamp is known as Lake Choga, whose western end is traversed for some 80 kilometres by the Nile with a perceptible current. These large sheets of papyrus and water, which cover an area of over 2000 square kilometres, must cause as much loss by evaporation as they receive by direct rainfall. The Victoria Nile leaves the lake in a broad stream some 900 metres wide, past Mruli station, on to Fowera. In the longitudinal section on Plate II, I have considered Fowera as 1060 metres above sea level, and the slope upstream of it as ¹⁄₂₀₀₀₀. From Fowera to the foot of the Murchison Falls, the Nile falls 377 metres on a length of 68 kilometres, and then in the next 30 kilometres reaches Lake Albert. Considerable quantities of floating pistea weeds pass down the Victoria Nile from Lake Choga. They are well churned up between Fowera and the Murchison Falls, but finally enter Lake Albert. It would be easy to develop electricity to work a railway along these 68 kilometres.
