The Kalambo Falls on the Kalambo River is a 772ft (235m) single drop waterfall on the border of Zambia and Tanzania at the southeast end of Lake Tanganyika. The falls are some of the tallest uninterrupted falls in Africa. Downstream of the falls the Kalambo Gorge which has a width of about 1 km and a depth of up to 300 m runs for about 5 km before opening out into the Lake Tanganyika rift valley.
Falls were first seen by white people approximately in 1913. Initially it was assumed that the height of falls exceeds 300 m, but measurements in 1920s gave a more modest result above 200 m. Later measurements in 1956 gave a result 221 m. After this there have been made several more measurements, each with slightly different results. Widths of falls is 3.6 - 18 m. Sources
