The Rift Valley lakes are a group of lakes in the East African Rift that runs north-south through the eastern side of the African continent, from Ethiopia in the north to Malawi in the south. These lakes include some of the oldest, largest, and deepest lakes in the world. Many are freshwater ecoregions of great biodiversity, while others are alkaline "soda lakes" supporting highly specialized organisms.
Lake Nakuru is one of the Rift Valley soda lakes at an elevation of 1754 m above sea level. It lies to the south of Nakuru, in the rift valley of Kenya, and is protected by Lake Nakuru National Park. The lake's abundance of algae used to attract a vast quantity of flamingos that famously lined the shore. Other birds also flourish in the area, as do warthogs, baboons, and other large mammals. Eastern black rhinos and southern white rhinos have also been introduced.
