Lake Bogoria
Rift Valley Region
Lake Bogoria is a saline and alkaline lake located in the Rift Valley region of Kenya, approximately 120 km north of Nakuru and 240 km north of Nairobi. It lies in a volcanic half-graben basin and is part of a chain of alkaline lakes that support one of the world's largest populations of lesser flamingos. The lake is characterized by its shallow waters, fluctuating between 988 and 996 meters in elevation, and covers an area of roughly 3,300 hectares, expanding during rainy seasons. Its maximum depth reaches about 10 to 12 meters, making it relatively stable hydrologically compared to other Rift Valley lakes. The lake's surroundings include varied wetlands formed by fault lines and hot springs, contributing to a rich biodiversity. Designated as a Ramsar site and protected as Lake Bogoria National Reserve since 1973, it offers a unique ecosystem where flamingos and other wildlife thrive despite the semi-arid climate. The lake's geothermal activity is notable, with hot, warm, and cold springs around its shores, creating a fascinating natural spectacle.

History
Lake Bogoria was formerly known as Lake Hannington, named after Anglican missionary James Hannington who visited the area in 1885.
It became a protected National Reserve on November 29, 1973, recognized for its ecological importance and as a habitat for flamingos.
Historically, it was once part of a larger freshwater lake system connected to Lake Baringo.
Over centuries, tectonic activity and climatic changes shaped its current saline and alkaline state, with fluctuating water levels influenced by rainfall and evaporation rates characteristic of the semi-arid Rift Valley environment.
Place Guide
Geothermal Hot Springs and Geysers
These natural features along the lake's shores are caused by volcanic activity beneath the Rift Valley and offer spectacular sights of steaming water and bubbling mud pools.
Lesser Flamingo Colonies
Lake Bogoria is periodically home to vast colonies of lesser flamingos, which feed on the cyanobacteria thriving in the alkaline waters, creating one of the world's most impressive bird spectacles.
