Lake Bogoria is a located in the northern Kenyan Rift Valley. The lake is famous for the pink flamingoes which are found in large numbers. Geothermal activity in the form of hot springs and geysers are located on the western shore.
Lake Bogoria has the largest number of geysers in Africa.

Lake Bogoria is possibly the most interesting of the Kenyan Rift Valley lakes. The lake is 17 x 3.5 km, and occupies a narrow, asymmetric half-graben within the rift
floor. Bogoria Escarpment rises 700 m on the eastern side of the lake. A magnitude 7.0 earthquake occurred at the lake in 1828.
Water in the Lake Bogoria derives from rainfall on the lake surface (750 mm/ yr), about 200 hot springs, and streams which feed into the lake. There is no surface outflow from the lake, and most water is lost by evaporation (2600 mm/ yr), resulting in salinity more than twice that of seawater.
The water contains sodium, carbonate and bicarbonate ions, with a pH of 9.5 to 10.5. The lake chemically stratified, even though it has a depth of only 12 m. The surface layer has a salinity of 60 g/l TDS, and the bottom layer of brine with a salinity of about 90 g/l TDS.
The surface water is periodically oxygenated by dilute inflow, whereas the bottom waters remain anoxic. More than a million flamingoes have been
recorded on the 36 sq km lake.
The largest earthquake in the Kenyan Rift (magnitude 6.0) occurred 25 km from Lake Bogoria.
Lake Bogoria has the most spectacular geothermal activity in Kenya. Most springs occur along fault lines. Many boil constantly, and some show periodic geyser-like eruptions. The spring waters are sodium bicarbonate, with total dissolved solids of 26 g/L TDS, and pH of 7.1 to 9.9. The fumaroles discharge steam, C02, and minor H2S and CH4.
