The Elgeyo Escarpment rises to over 1,830 metres (6,000 ft) above the Kerio valley in places.[2] The Kerio continues northward, often through deep and narrow valleys, to enter Lake Turkana in a delta just south of the delta formed by the Turkwel and Lokichar rivers. The Kerio and Turkwel contribute 98% of the river water flowing into Lake Turkana on Kenyan territory (which makes up only 2% of the total riverine inflow).
