Hotel accommodation is available near Loboi village at the north end of the lake. 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. The lake was formerly named after Bishop James Hannington who visited in 1885. At times, during the late Pleistocene it might have been united with a larger precursor of modern Lake Baringo, but this is still uncertain. At times it might have overflowed northward towards Lake Baringo. 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. Austria (belonging to the Brachionus plicatilis cryptic species complex) is found in high densities. the monogonont rotifer species Brachionus sp. Although hypersaline, the lake is highly productive with abundant cyanobacteria ( Arthrospira fusiformis) that feed the flamingoes, but few other organisms inhabit the lake e.g. The lake itself is meromictic (stratified) with less dense surface waters lying on a denser more saline bottom waters. The lake has no surface outlet so the water becomes saline mainly through evaporation, which is high in this semi-arid region. The lake waters are alkaline ( pH:10.5) and saline (up to 100 g/L total dissolved salts). Lake Bogoria also contains the highest concentration of true geysers in Africa (at least 18 are known). Other springs discharge directly from the lake floor. They originate from inflow from the Sandai and Emsos rivers, and from about 200 alkaline hot springs that are present at three onshore sites: Loburu, Chemurkeu, and a southern group (Ng'wasis, Koibobei, Losaramat). The lake waters contain large concentrations of Na +, HCO 3 − and CO 3 2− ions. Geyser activity is affected by the fluctuations of lake level, which may inundate or expose some geysers. In four locations around the lake can be observed at least 10 geysers, which erupt up to 5 m high. The lake is also famous for geysers and hot springs along the bank of the lake and in the lake. Local features include the Kesubo Swamp to the north and the Siracho Escarpment to the east, both within the National Reserve. Satellite image of Lake Bogoria taken from World Wind. 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 km 2. The lake is a Ramsar site and Lake Bogoria National Reserve has been a protected National Reserve since November 29, 1973. 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. 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.
