The Ganale Doria River (Somali : Webiga Janaale) (also transliterated as Genale Dorya) is a perennial river in southeastern Ethiopia. Rising in the mountains east of Aleta Wendo, the Ganale flows south and east to join with the Dawa at the border with Somalia to become the Jubba. The river's tributaries include the Welmel, Weyib (also known as Gestro), and Mena. The Del Verme Falls is a notable feature of its middle course.
According to materials published by the Ethiopian Central Statistical Agency, the Ganale has a total length of 858 km (533 mi). [3] The Ethiopian Ministry of Water Resources, describes the catchment area of the Ganale Dorya-Dawa river basin as 82,600 km2 (31,900 sq mi) in size, with an annual runoff of 5.80 billion cubic metres (205×10 9 cu ft), and specific discharge of 1.2 litres per second (0.042 cu ft/s) per square kilometre. [4] The catchment area is estimated as having the potential to irrigate 1,070 km2 (410 sq mi), and to generate 9270 gigawatt-hours per year. [5]
The river Ganale was renamed Ganale Doria by the Italian explorer Vittorio Bottego after the Italian biologist Giacomo Doria. [6]
The Genale Doria is historically important because it served as the boundary between Sidamo and Bale Provinces. The confluence of the Ganale Doria with the Dawa is notable as the former starting point for the boundary between Ethiopia and Kenya to the west, and the starting point for the boundary between Ethiopia and Somalia to the east. [7] In 1936, the Battle of Genale Doria was fought to the south of the river's course.
The Jubba River or Juba River is a river in southern Somalia which flows through the region of Jubaland. It begins at the border with Ethiopia, where the Dawa and Ganale Dorya rivers meet, and flows directly south to the Somali Sea, where it empties at the Goobweyn juncture. The Jubba basin covers an area of 749,000 km2 (289,000 sq mi). The Somali regional state of Jubaland, formerly called Trans-Juba, is named after the river.
Vittorio Bottego was an Italian army officer and one of the first Western explorers of Jubaland and southern Ethiopia, where he led two expeditions. He was the first European explorer to follow the course of the lower Omo River to its confluence with Lake Turkana and to reach Lake Abaya, which he renamed Lake Margherita after Queen Margherita of Savoy wife of King Humbert I of Italy.
The Mareb River, also known as the Gash River, is a river flowing out of central Eritrea. Its chief importance is defining part of the boundary between Eritrea and Ethiopia, between the point where the Mai Ambassa enters the river at 14°53.6′N37°54.8′E to the confluence of the Balasa with the Mareb at 14°38′N39°1.3′E.
The Omo River in southern Ethiopia is the largest Ethiopian river outside the Nile Basin. Its course is entirely contained within the boundaries of Ethiopia, and it empties into Lake Turkana on the border with Kenya. The river is the principal stream of an endorheic drainage basin, the Turkana Basin.

The battle was primarily fought in the area along the Genale Doria River valley between Dolo and Negele Boran.
The Dawaro River is found in East Africa, covering an area of 58,961 km2. It flows through three major countries: Kenya, Ethiopia, and Somalia, with 81% found in Ethiopian territory. It is known for its complex geological environment, evident through its diverse lithology and structural framework, coming from the river's closeness to multiple volcanic-tectonic events. The wide river has gentle slopes either side of its exposed bedrock. The Dawa river flows south east to form part of both the Ethiopia–Somalia border and the Ethiopia–Kenya border. Awata, Digati, and Mormora are the only significant off-flowing rivers to Dawa.

Ganale Doria is a dam located near Genale on the river Shabelle. It was built in the south of Somalia in the 1920s along with an extensive network of canals. The dam was strongly promoted by Cesare Maria De Vecchi - Italian governor of Italian Somalia from 1924 to 1928 - in order to provide water for irrigation of a vast territory between Genale, Merca and Vittorio di Africa, to be given in concession to colonists.
The Genale Dawa III Power Station, also GD-3 Power Station, is a hydroelectric power station across the Ganale Doria River in Ethiopia. Construction began circa March 2011 and the power station was commercially commissioned in February 2020. The renewable energy infrastructure development is owned by the government of Ethiopia and was constructed by China Gezhouba Group, a subsidiary of China Energy Engineering Corporation at an estimated cost of £352.7 million, co-financed by the Exim Bank of China and the Ethiopian Government.
