Koka Reservoir, reservoir in Ethiopia
Koka Reservoir is an artificial lake in south-central Ethiopia, formed by a dam built across the Awash River. It supplies drinking water and irrigation to surrounding communities as well as to the capital, and supports an active local fishing economy.
The dam was built between 1957 and 1960 by an Italian team, with the power plant starting operations in August 1960. The project marked a turning point for the region and has continued to supply electricity to Addis Ababa ever since.
Local communities know this place by two names: 'Haroo Qooqaa' in Oromo and 'Koka Hayk' in Amharic, each reflecting a different group's relationship with the water. Along the banks, you can watch small fishing boats, people washing clothes, and animals being led to drink throughout the day.
The shores of the reservoir are open and easy to walk along, making it a good spot for watching birds and local daily activity. Early morning is the most rewarding time to visit, when mist often sits on the water and the light is soft.
Despite its role in water supply and power generation, the reservoir has also become a notable bird-watching spot in Ethiopia, drawing a wide variety of waterbirds. Visitors who come without expecting wildlife often leave surprised by how many species can be seen from the shore.
