      Lake Tana is Ethiopia’s largest lake, the main source of the Blue Nile   
      River, and a hotspot of biodiversity. It was designated as a UNESCO   
      Biosphere Reserve in 2014 and is also recognized by BirdLife   
      International as an Important Bird Area (IBA).   
      
      The lake sits in the northwest corner of the Ethiopian plateau about   
      350 miles (563 km) northwest of Addis Ababa. Lake Tana is very shallow,   
      with a maximum depth of 45 feet (14 meters). This shallow depth allows   
      sediment to swirl in the lake, carried by currents caused by the 60   
      rivers that pour into the lake or by strong winds. Sediment can color   
      the water in shades of tan or green, and frequent algae blooms can also   
      tint the lake with a green tone. There are 37 islands in Lake Tana,   
      many of which support large colonies of birds while others are sites of   
      ancient churches and monasteries.   
      
      Because of the location of Lake Tana, it is an important stopover and   
      wintering site for many migratory birds on the flyway between Europe,   
      Asia and Africa. The large undisturbed reedbeds around the lake serve   
      as breeding, feeding, and roosting sites for endemic and rare species,   
      such as the Wattled Crane and Black-crowned Crane and are essential for   
      their survival.   
      
      On May 11, 2023, the Moderate Resolution Imaging Spectroradiometer   
      (MODIS) on board NASA’s Terra satellite acquired a true-color image of   
      Lake Tana. The multi-colored waters of the lake stand out in high   
      contrast to the rugged Ethiopian plateau surrounding the lake. Dek   
      Island, the largest of Lake Tana’s many islands, is easily visible in   
      the southwestern section of the lake.
