It is not known exactly to what extent dams in Ethiopia would reduce the flow of water to Sudan and Ethiopia. Assuming an evaporation rate of 1 meter per year, an irrigated area of 200,000 hectares and a combined reservoir area of 1,000 km2, the flow of the Nile could be reduced by 3 billion cubic meters per year, equivalent to about 5 percent ...
The Koka Reservoir (Amharic: ኮካ ሐይቅ; Oromo: Haroo Qooqaa) is a reservoir in south-central Ethiopia. It was created by the construction of the Koka Dam across the Awash River . The reservoir has an area of 180 square kilometres (69 sq mi).
The dam's spillway is 108 m (354 ft) long and floodgate-controlled with a maximum discharge capacity of 18,000 m 3 /s (640,000 cu ft/s). Water above 873 m (2,864 ft) above sea level can be discharged through its gates. Feeding the dam's power house are two penstocks that each branch into five separate tunnels for each individual turbine.
The dam is 1,700 m (5,600 ft) long and 40 m (130 ft) tall. Construction on the dam began in 1988 but work was halted in 1994. In 1995 construction restarted with a new construction firm. The power station was commissioned in 2004. [2] Water from the dam is diverted through a 9.2 km (5.7 mi) long tunnel to an underground power station downstream.
The Government of Egypt, a country which depends on the Nile for about 90% of its water, [28] has demanded that Ethiopia cease construction on the dam as a precondition to negotiations, has sought regional support for its position, and some political leaders have discussed methods to sabotage it.

Tendaho Dam is an earth-filled dam in the eastern Afar Region of Ethiopia. It is situated on the Awash River, and its reservoir also receives the output of the Mille River. The dam is a project of the Ethiopian Water Works Construction Enterprise (EWWCE). Project planning began in 2005, with construction occurring from 2010 to 2014.
Ethiopia sees the dam as essential to its development but downstream Egypt — the Arab world’s most populous country — fears it will restrict its share of the Nile water, critical for its ...
