      Sitting in the arid landscape of Africa’s Eastern Rift Valley, Lake   
      Turkana is both the largest permanent desert lake and the largest   
      alkaline lake on Earth. The long, narrow lake—it stretches 150 miles   
      (250 km) from north to south and 27 miles (250 km) across—is located   
      almost entirely in Kenya. At the northernmost tip, a delta is formed by   
      the influx of the Omo River. This area, as well as the Omo River   
      itself, belongs to Ethiopia.   
      
      The lake’s salty, alkaline water creates a unique ecosystem, where   
      species have adapted to harsh conditions. Turkana contains about 50   
      different species of fish, with 11 species found only in this lake. It   
      is home to the largest remaining population of the Nile crocodile and   
      supports more than 350 native and migratory bird species.   
      
      Three rivers, the Turkwel, Kerio, and Omo, provide water to Lake   
      Turkana, but Turkwel and Kerio are seasonal. The Omo River provides 90   
      percent of the inflow or about 19 billion cubic meters (671 cubic feet)   
      of water each year. No rivers exit the lake, so the only outflow is by   
      evaporation, which readily occurs in the hot, dry climate. The Omo   
      River not only provides water to Lake Turkana, but its waters are also   
      used for hydroelectric power generation, and some are diverted for   
      agriculture.   
      
      Currently, a new hydroelectric dam is under development in Ethiopia as   
      part of an expanding system of power plants that should double the   
      electricity output as well as increase industrial farming. The Gilgel   
      Gibe III dam will likely have major impacts on Lake Turkana, the   
      species that rely on the lake for life, and the people relying on the   
      lake for their livelihoods.   
      
      The Moderate Resolution Imaging Spectroradiometer (MODIS) on board   
      NASA’s Terra satellite acquired a true-color image of Lake Turkana on   
      December 21, 2022. The Omo Delta is visible as a large dark area at the   
      northern tip of the long, shallow lake.
