Loburu Hot Springs is located in Baringo County in the Rift Valley Province of Kenya. Loburu sits in one of Kenya’s largest geothermal areas, near Lake Bogoria. There are 32 separate springs, three of which have continuous geysers, earning them the name “perpetual spouters.” Tourists can take excursions to the lake to enjoy this scenic marvel.
The best place to see geysers in Africa is Lake Bogoria. In several locations around this lake at one time can be seen more than 10 geysers, but the best known here are Loburu Geysers.
Lake Bogoria is one of Rift Valley Lakes. Each of these lakes is unique and Lake Bogoria is not an exception. This lake is alkaline – with a pH of 10.5 at the western bank. Lake water is twice as saline as seawater. Lake gets water only from the hot springs and some perennial rivers and it has no outlet.
As there is no outlet, the level of the lake is regulated just by the rain and heat. This 34 km long lake might rise or fall by 0.15 – 0.3 m in a rather short time.
The alkaline, warm lake water is excellent media for cyanobacteria Arthrospira fusiformis and some other microorganisms. These organisms serve as a food for lesser flamingo (Phoeniconaias minor) and some other birds. In the lake live approximately 0.5 million flamingos – the highest density of these birds worldwide and approximately half of world’s population of these beautiful birds. Sometimes the number of the birds increases up to 2 millions.
Loburu Hot Springs form the largest geothermal field at Lake Bogoria. Loburu river has formed a small delta at the western bank of lake and part of the hot springs are to the north from river and part – to the south. Springs are powerful, they form short streams. Part of the hot springs have formed small pools, some more than 2 m deep. Some springs instead of pools have formed cones. Just in few places there is observed thin layer of siliceous sinter deposits – an indication of geyser activity in the recent past. Such geysers without siliceous sinter (geyserite) are rare in the world.
In the northern group are some 32 hot springs. 3 of these springs are perpetual spouters (hot springs which shoot water in the air without interruption) but none is geyser. Some 11 springs have travertine deposits around them.
The southern group in August 2007 (1) had some 20 hot springs above the lake level and several more under the lake level. Temperature of springs is between 39 and 98.5 °C. At the northern end of southern group are located six geysers.
Five geysers belong to the group named KL19 – their vents are close together, some metres apart. One of these geysers in 1995 was up to 3.5 m high, erupting every 5 – 8 minutes, later it became less powerful. Approximately 30 m to the north is geyser KL30. All these geysers are not active at the same time. For example in August 2006 the geyser KL30 erupted at regular 45 minutes interval, reaching 5 m height, but already in 2007 the rising level of lake suppressed its activity.
Geysers are littered with boulders and pieces of wood – local people throw them in the geysers to initiate eruptions.
