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, like Lake Nakuru, Lake Elementeita, and Lake Magadi further south in the Rift Valley, and Lake Logipi to the north, is home at times to one of the world's largest populations of lesser flamingos. The lake is a Ramsar site and Lake Bogoria National Reserve has been a protected National Reserve since November 29, 1973. Lake Bogoria is shallow (about 10 m depth), and is about 34 km long by 3.5 km wide, with a drainage basin of 700 km². It is Located in Baringo County.^[2]

Local features include the Kesubo Swamp to the north and the Siracho Escarpment to the east, both within the National Reserve. The lake is also famous for geysers and hot springs along the bank of the lake and in the lake. In four locations around the lake can be observed at least 10 geysers, which erupt up to 5 m high.^[3] Geyser activity is affected by the fluctuations of lake level, which may inundate or expose some geysers.
