Murchison Falls, also known as Kabarega Falls, is a waterfall on the Nile. It breaks the Victoria Nile, which flows across northern Uganda from Lake Victoria to Lake Kyoga and then to the north end of Lake Albert in the western branch of the East African Rift. The outlet of Lake Victoria sends around 300 cubic metres per second of water over the falls, squeezed into a gorge less than ten metres wide. Sir Samuel Baker named them after Sir Roderick Murchison, president of the Royal Geographical Society. The falls lend their name to the surrounding Murchison Falls National Park.
