Site description A very large, isolated, chloro-carbonate alkaline lake, the northernmost and by far the largest of the chain of Rift Valley lakes in Kenya. The Omo river delta at the extreme northern end of the lake lies within Ethiopia (IBA ET069). Turkana’s water is brackish, but drinkable, and the lake holds freshwater fish. The c.600 km of lake shore vary greatly in substrate, from rock (most of the southern sector, the central eastern shore, and North, Central and South Islands) to pebble, sand (most of the north-western shore, and patches elsewhere) and mud (at Loiyengalani, El Molo and Allia Bays, the Omo delta and the inlets of the Turkwel and Kerio rivers). Beds of the submerged plant Potamogeton pectinatus occur in the most sheltered muddy bays. The country surrounding the lake is semi-desert with sparse vegetation: annual rainfall averages less than 250 mm (substantially less in some places), and it may not rain for several years at a stretch. South and Central Islands are National Parks and, in the north-east, c.13% of the shoreline is protected within Sibiloi National Park.

Other biodiversity Lake Turkana is rich in fish, with 47 species, seven of which are endemic. The sheltered muddy bays with beds of waterweed Potamogeton are important for fish spawning. The fish in turn support a large population (estimated at some 14,000 in 1968) of Crocodylus niloticus.
