Lakes and Rivers
The northern part of the rift is crossed by two large mountain ranges, the Rwenzori Mountains between Lake Albert and Lake Rutanzige (formerly Lake Edward) and the Virunga Mountains between Lake Rutanziga and Lake Kivu. The Virungas form a barrier between the Nile Basin to the north and east and the Congo Basin to the west and south. Lake Rutenzige is fed by several large rivers, the Rutshuru River being one, and drains to the north through the Semliki River into Lake Albert. The Victoria Nile flows from Lake Victoria into the northern end of Lake Albert and exits as the White Nile from a point slightly to the west, flowing north to the Mediterranean.
South of the Virungu, Lake Kivu drains to the south into Lake Tanganyika through the Ruzizi River. Lake Tanganyika then drains into the Congo River via the Lukuga River. It seems likely that the present hydrological system was extablished quite recently when the Virunga volcanoes erupted and blocked the northward flow of water from Lake Kivu into Lake Edward, causing it instead to discharge southward into Lake Tanganyika. Before that Lake Tanganyika, or separate sub-basins in what is now the lake, may have had no outlet other than evaporation. The Lukuga has formed relatively recently, providing a route through which aquatic species of the Congo Basin could colonize Lake Tanganyika, which formerly had distinct fauna.

Famous quotes containing the words lakes and, lakes and/or rivers:
“While the very inhabitants of New England were thus fabling about the country a hundred miles inland, which was a terra incognita to them,... Champlain, the first Governor of Canada,... had already gone to war against the Iroquois in their forest forts, and penetrated to the Great Lakes and wintered there, before a Pilgrim had heard of New England.”
—Henry David Thoreau (1817–1862)
“If the fairest features of the landscape are to be named after men, let them be the noblest and worthiest men alone. Let our lakes receive as true names at least as the Icarian Sea, where “still the shore” a “brave attempt resounds.””
—Henry David Thoreau (1817–1862)
“I remember once dreaming of pushing a canoe up the rivers of Maine, and that, when I had got so high that the channels were dry, I kept on through the ravines and gorges, nearly as well as before, by pushing a little harder, and now it seemed to me that my dream was partially realized.”
—Henry David Thoreau (1817–1862)
