Lake Bogoria (formerly Lake Hannington) is a saline, alkaline lake that lies in a volcanic region in a half-graben basin south of Lake Baringo , Kenya, a little north of the equator. Lake Bogoria, is periodically home to one of the world’s largest populations of lesser flamingos. Although the lake is in a semi-arid part of Kenyan Rift Valley , it is surrounded by numerous and varied wetlands along its shorelines, along faults where hot, warm and cold springs have developed, and along rivers that run across the rift floor. Lake Bogoria is in a geothermally active part of the Kenya Rift Valley, and is famous for geysers and hot spring along the bank of the lake and in the lake. There are about 200 hot springs, most of which are distributed along the shoreline .

The lake supports more than 300 water bird species. It is an important stop over site for a population of up to 1.5 million migratory birds, notably for the lesser flamingos (Phoeniconaias minor). Its immediate surroundings are a critical habitat for vulnerable species such as the common hippopotamus (Hippopotamus amphibius) and African lion (Panthera leo); another important species is the greater kudu (Tragelaphus strepsiceros). The lake’s stable water level makes it doubly important during periods of drought, when water levels in other East African lakes drop.
