Nigat Lake

Nigat Lake (Amharic: ንጋት ሐይቅ; lit. Lake of Dawn) is an artificial reservoir in Ethiopia, created by the impoundment of the Blue Nile River by the Grand Ethiopian Renaissance Dam (GERD). At full capacity, it is one of the largest reservoirs in Africa and among the largest worldwide, with a storage volume exceeding 70 billion cubic metres—greater than Lake Volta in Ghana, comparable to Lake Nasser on the Egypt–Sudan border, and ranking alongside global megaprojects such as Lake Kariba and China’s Three Gorges Reservoir. The name was officially designated in 2025 as the dam reached full water retention, symbolising Ethiopia’s aspirations for energy generation and development.
