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 Ruiziwitha 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 kilo- 
metres. 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 knowui 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 kilo- 
metres, 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, 1 have considered Fowera as 1060 metres above 
sea level, and the slope upstream of it as ^oooo ' 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.
