1. Lake Victoria is also known as Nalubaale & Ukerewe.  The largest lake in Africa and chief reservoir of the Nile, lying predominantly in Uganda and Tanzania while also bordering Kenya. It is the second largest freshwater lake in the world with only North America’s Lake Superior being greater. Whilst searching for the source of the Nile British explorer John Hanning Speke discovered the lake in 1858, being the first European to do so, and named it for Queen Victoria.
