Lake Margherita or Lake Abaja (Abaya Hayk in Amharic) is a lake in the Southern Nations Nationalities Region of Ethiopia. It was named in 1896 as Lake Margherita by the Italian explorer Vittorio Bottego, the first European to visit the lake, to honor the wife of king Umberto I of Italy, Queen Margherita.

However, the American explorer Arthur Donaldson Smith records that the local inhabitants, who included an eye witness of the event, told him that the Italian explorer Eugenio Ruspoli (died 1891) was killed by an elephant near the lake, which happened before Bottego reached Lake Abaya.[1]

Lake Margherita (or Abaja) is located in the Main Ethiopian Rift, east of the Guge Mountains. It is fed on its northern shore by the Bilate which rises on the southern slopes of Mount Gurage, and the Gidabo. The town of Arba Minch lies on its southwestern shore, and the southern shores are part of the Nechisar National Park. Just to the south is Lake Chamo. Lake Margherita is 60 kilometers long and 20 wide,[2] with a surface area of 1162 square kilometers.[3] It has a maximum depth of 13.1 meters and is at an elevation of 1285 meters.[3] There are a number of islands in this lake, the largest being Aruro;[4] others include Gidicho, Welege, Galmaka, and Alkali. The lake is red due to a high load of suspended sediments.[5] Lake Abaya does not always have an outflow, but in some years it overflows into Lake Chamo.

Savanna, known for its wildlife and birdlife surrounds the lake, which is also fished by local people. According to the Ethiopian Department of Fisheries and Aquaculture, 412 tonnes of fish are landed each year, which the department estimates is 69% of its sustainable amount.[6]
