Lake Victoria, in contrast, is the largest of the African Great Lakes and the chief reservoir of the Nile. Spanning Tanzania, Uganda and Kenya. It plays a crucial role in both local communities and the broader environmental balance of East Africa. Named by British explorer John Hanning Speke in 1858 after Queen Victoria, it is home to remarkable biodiversity, particularly the tilapia fish, a commercially significant species. However, like many African lakes, Lake Victoria faces challenges, including invasive species such as the Nile perch, which have disrupted its ecological balance.
