Lake Elmenteita, also spelled Elementaita, is a soda lake, in the eastern limb of East Africa's Great Rift Valley, about 120 km northwest of Nairobi, Kenya. Elmenteita is derived from the Masaai word muteita, meaning "dust place", a reference to the dry and dusty quality of the area, especially between January and March. In the south-to-north sequence of Rift Valley lakes, Elmenteita is located between Lake Naivasha and Lake Nakuru. At the southern end of the lake lie the "Kekopey" hot springs, in which the Tilapia Grahamii breed. The reedbeds nearby are fishing grounds for Night Herons and Pelicans.

History

The Lake Elmenteita area saw its first white settlement when Lord Delamere (1879-1931) established his Soysambu, a 48,000-acre (190 km2) ranch, on the western side of the lake. Delamere gifted the land nearest the lake to his brother-in-law, the Honorable Galbraith Lowry Egerton Cole (1881-1929), part of whose "Kekopey Ranch", where he is buried, is preserved today as the Lake Elementaita Lodge. 

The nearby Soysambu estate is still occupied by Lord Delamere's descendants, while Ututu House was built by Thomas P. G. Cholmondeley who was also instrumental in setting up the Soysambu conservancy. The conservancy covers 2/3 of the shoreline and is home to over 12000 wild animals. Lake Elmenteita has been a Ramsar site since 2005.

Ecology

Over 400 bird species have been recorded in the Lake Nakuru/Lake Elmenteita basin. Elmenteita attracts visiting flamingoes, both the Greater and Lesser varieties, which feed on the lake's crustacean and insect larvae and on its suspended blue-green algae, respectively. Tilapia were introduced to the lake from Lake Magadi in 1962 and since that time the flamingo population has dwindled considerably. The tilapia attract many fish-eating birds that also feed upon the flamingo eggs and chicks. Over a million birds that formerly bred at Elmenteita are now said to have sought refuge at Lake Natron in Tanzania. The lake's shores are grazed by zebra, gazelle, eland and families of warthog.

The Lake

The lake is normally very shallow (< 1 m deep) and bordered by trona-encrusted mudflats during the dry seasons. During the late Pleistocene and early Holocene, Lake Elmenteita was at times united with and expanded Lake Nakuru, forming a much larger dilute lake. Remnants of the former joined lake are preserved as sediments at various locations around the lake basins, including former shorelines.

Associated sites

Nearby is the Kariandusi Museum, at an important prehistoric site where stone handaxes and cleavers were discovered in 1928 by Louis Leakey. Elmenteita Badlands is a lava flow to the south of the lake, covered in bush and including some spectacularly scenic peaks.
