Lake Naivasha is a freshwater lake in Kenya, outside the town of Naivasha in Nakuru County, which lies north west of Nairobi. It is situated in the Great Rift Valley. The name derives from the local Maasai name ɛnaɨpɔ́sha , meaning “that which heaves,” a common Maasai word for bodies of water large enough to have wave action when it is windy or stormy. Naivasha arose from a British attempt to pronounce the Maasai name. Literally, Lake Naivasha means “Lake Lake.”
Location
Lake Naivasha is at the highest elevation of the Kenyan Rift valley at 1,884 metres (6,181 ft) in a complex geological combination of volcanic rocks and sedimentary deposits from a larger Pleistocene Era lake. Apart from transient streams, the lake is fed by the perennial Malewa and Gilgil rivers. There is no visible outlet, but since the lake water is relatively fresh it is assumed to have an underground outflow.[2]
