Lake Bogoria (formerly Lake Hannington) is a
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.
Chemistry and ecology
The lake waters contain large concentrations of Na+, HCO3− and CO32− ions. They originate from inflow from the
The lake has not always been saline. Sediment cores from the lake floor have shown that freshwater conditions existed for several periods during the past 10 000 years, and that lake level was up to 9 m higher than its present elevation of about 990 m. At times it might have overflowed northward towards Lake Baringo. At times, during the late Pleistocene it might have been united with a larger precursor of modern Lake Baringo, but this is still uncertain.
History
The lake was formerly named after Bishop James Hannington[4] who visited in 1885.
The lake area was the traditional home of the Endorois people, who were forced to leave the area in the 1970s and are now challenging their removal at the African Commission on Human and Peoples' Rights.
Accommodations
Hotel accommodation is available near Loboi village at the north end of the lake. Camping is permitted at the southern end of the lake (see North Lewis, 1998, for details).
