caption_attribution_description: English: View of the Ewaso N'giro River in Kenya
context_page_description: Ewaso Ng'iro is a river in Kenya which rises on the west side of Mount Kenya and flows north then east and finally south-east, passing through Somalia where it joins the Jubba River.
  The upper basin of the Ewaso Ng'iro River is 15,200-square-kilometre. The river has a continuous water supply due to the glaciers on Mount Kenya. Ewaso Ng'iro feeds into Lake Ol Bolossat, the only lake in Nyandarua county and the larger Central Kenya. Ewaso Ng'iro crosses seven arid to semi-arid landscapes. It is characterized by vastly different physiographic features and species and has become a fundamental component to the survival of the wildlife, as well as the expansion of human population and socio-economic developments. Water, the limited land resource provided by the Ewaso Ng’iro watershed is unevenly distributed throughout the higher and lower regions of the catchment due to the large percentage necessary to maintain agricultural practices and climatic changes.
  The river's name is derived from the local community's language. It means the river of brown or muddy water. It is also called by some the "Ewaso Nyiro."
  In the arid north of Kenya, water means life.

  The upper basin of the Ewaso Ng'iro River is 15,200-square-kilometre (5,900 sq mi). The river has a continuous water supply due to the glaciers on Mount Kenya. Ewaso Ng'iro feeds into Lake Ol Bolossat, the only lake in Nyandarua county and the larger Central Kenya. Ewaso Ng'iro crosses seven arid to semi-arid landscapes.  It is characterized by vastly different physiographic features and species and has become a fundamental component to the survival of the wildlife, as well as the expansion of human population and socio-economic developments. Water, the limited land resource provided by the Ewaso Ng’iro watershed is unevenly distributed throughout the higher and lower regions of the catchment due to the large percentage necessary to maintain agricultural practices and climatic changes (Mutiga, Su, and Woldai 3).
  The river's name is derived from the local community's language. It means the river of brown or muddy water. It is also called by some the "Ewaso Nyiro."
  In the arid north of Kenya, water means life. The waters of this great river draw wildlife in great numbers to its banks, creating an oasis of green. Samburu, Shaba and Buffalo Springs National Reserves in Northern Kenya teem with wildlife in an otherwise arid land, because of the water of the river.
  Below Sericho, the river expands into the Lorian Swamp, a large area of wetlands. The ecological diversity throughout the catchment  is unique to the Ewaso Ng’iro watershed specifically, as it originates from the high agriculturally potential lands of Mount Kenya, right at Thome Area of Nanyuki-Laikipia County, that means the exact start point of this river is at the Thome village where it is formed out of coveyance of Naromoru River, sourcing water from Mt. Kenya and Ngarinyiru River sourcing water from Aberdares and it flows over the following seven arid to semi arid land (ASAL) districts: Meru, Laikipia, Samburu, Isiolo, Wajir, Marsabit, and Garissa (Said et al. 14). Following the independence of Kenya, the stretches of land covered by the Ewaso Ng’iro watershed shifted ownership from the  colonial farmers to small scale farmers (Thenya et al. 2). The catchment became a main resource for the small scale farmers to support their agropastorial practices and developing livelihoods (Thenya et al. 2).
  Ewaso Narok river is one of its tributaries. Thomson's Falls near Nyahururu town are located along Ewaso Narok.
