Lake Naivasha is a freshwater lake in Kenya, outside the town of Naivasha in Nakuru County, which lies north west of Nairobi. It is part of the Great Rift Valley. The name derives from the local Maasai name Nai’posha, meaning “rough water” because of the sudden storms which can arise.


The lake is home to a variety of types of wildlife including over 400 different species of bird and a sizeable population of hippos. The fish community in the lake has been highly variable over time, influenced by changes in climate, fishing effort and the introduction of invasive species. The most recent shift in the fish population followed the accidental introduction of common carp in 2001.Nine years later, in 2010, common carp accounted for over 90% of the mass of fish caught in the lake. Lake Naivasha is home to a wide variety of wildlife including a sizeable population of hippos which usually invade our property during their nightly forays for food. Being a freshwater lake, it also has a healthy fish population to include Black bass, Tilapia and Crayfish which attract a variety of fish-eating birds such as Long-tailed and Great Cormorants, along with Fish Eagles, Pelicans, and various types of Kingfishers


Apart from transient streams, Lake Naivasha is fed by the perennial Malewa and Gilgil rivers and, most unusually, it now has no visible outlet. However, it must be assumed that such a large body of water has to have an underground outflow through a volcanic fissure or similar somewhere beneath the expanse of its lake bed, and it has been suggested that the water emerges through the fresh but hot water springs at Lake Magadi, an otherwise brackish and pinkish coloured soda lake 120kms to the south.


Because this is a volcanic area, as witnessed by Mount Longonot, an extinct nearby volcano to the south east, and ancient fumaroles – including the tiny but spectacular Crater Lake – to the west, Kenya is blessed with the presence of the Olkarria Geothermal electrical generating complex – high in the hills just to the south – which feeds massive amounts of much needed power into the national grid.


Contact Diane, John as your guide is a must! He helps you to spot the birds, and as your eyes get used to looking there is a real buzz spotting all types of heron and eagles. Wow do they look good flying or guarding their territory. So many varieties and colours, kingfishers and lots more to record.
