Boreda Abaya was one of the 77 woredas in the Southern Nations, Nationalities, and Peoples' Region of Ethiopia. Part of the Semien Omo Zone, Boreda Abaya was bordered on the south by Arba Minch Zuria, on the southwest by Chencha, on the west by Kucha, on the north by Humbo, and on the east by Lake Abaya which separates it from the Oromia Region. Aruro Island, the largest island in Lake Abaya, was administratively part of this woreda. Towns in Boreda Abaya included Birbir and Zefene. Boreda Abaya was separated for Boreda and Mirab Abaya woredas.
Arnold Weinholt Hodson passed through Boreda soon after he had begun his career as the British resident in southern Ethiopia (1914-1923). At the time, it was under the government of Likamaquas Habte Mikael. As for the terrain, Hodson described it as "extremely hilly, and rises to an elevation of nearly 7000 feet."[1]
