Site description Elmenteita is a shallow alkaline lake (1,800 ha; maximum depth 1.9 m) lying on the Rift Valley floor some 20 km south-east of Nakuru town. It is fed by the Kekopey hot springs at its southern end, and two small streams, the Meroronyi and Kariandusi, flowing from the eastern plateau. The surrounding landscape is characterized by dramatic rocky faults, volcanic outcrops and cones. Rainfall is erratic and averages less than 600 mm/year. To the east, the lake is flanked by small-scale agriculture, while several large ranches surround the remainder. The northern and south-eastern lakeshores are open and flat, a spectacular cliff rises to the north-east, and the western shores are broken and rocky. The natural vegetation is mainly Acacia and Tarconanthus camphoratus bushland interspersed with Themeda triandra grassland. Patches of Acacia xanthophloea woodland occur near the shore, and formerly covered a large area south of the lake. The IBA consists of the lake and its surrounding shoreline, including the hot springs and the cliffs, and the Soysambu Wildlife Sanctuary (5,400 ha), part of the Delamere Estate, that abuts the lake to the north and west.

Other biodiversity Soysambu holds good populations of large mammals, including an introduced population of Giraffa camelopardalis rothschildi. The snake Bitis worthingtonii, endemic to the central Rift Valley above 1,500 m, is known from here. The cichlid fish Oreochromis alcalicus grahami, endemic to alkaline lakes in this part of the Rift Valley, occurs in the hot springs and has recently spread to the main lake.
