 Another name for this body of water is Lake Egogi (or Egogi Bad), which is the name L. M. Nesbitt's Afar guide gave it when the Italian explorer became the first European to see it in 1928.The single island in Lake Afrera, Franchetti Island (also known as "Deset"), located in the southern part of the lake, is considered the lowest-lying island in the world.Unlike other saline lakes in Ethiopia (e.g., Lakes Abijatta, Shala, and Chitu), the pH of Lake Afrera is low and in the acidic range.
