Is that a town directly below the dam?

Ethiopia’s Minister of Water and Energy, Habtamu Itefa, claimed that approximately 15,000 Ethiopians workers were reported to have died over the course of the dam project’s 14-year construction.[93][94] However, senior engineers on the project refuted the number, calling it a “misinterpretation”, and suggested that the number of deaths was much smaller, likely under 100.[95]
