Editing Kerio River (section)

==Course==

The Kerio River rises on the north slopes of the Amasya Hills to the west of Lake Bogoria.{{sfn|Hughes|Hughes|1992|p=192}}
It flows northward through the [[Kerio Valley]] between [[Tugen Hills]] and [[Elgeyo Escarpment]].
The Elgeyo Escarpment rises to over {{convert|1830|m|ft}} above the Kerio valley in places.{{sfn|Fitzpatrick|Parkinson|Ray|2006|p=430}}
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 River|Turkwel]] and [[Lokichar River|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). In their lower courses both these rivers are seasonal.{{sfn|Hughes|Hughes|1992|p=192}}

Near its source the Kerio River is fed by two major tributaries flowing down the Elgeyo Escarpment: Arror River, and Embobut River.
