PARIS — Ethiopia's construction of a massive power dam on the Blue Nile is raising tensions with Egypt, which depends on the river for 90 percent of its water supply.

As the neighbors and Sudan meet in Washington Wednesday for mediated talks on the potential conflict flashpoint, here is some background.


At 6,695 kilometers, the Nile is one of the world's longest rivers and a crucial supplier of water and hydropower in a largely arid region.

Its basin of more than three million square kilometers covers 10 countries: Burundi, Democratic Republic of Congo, Egypt, Ethiopia, Kenya, Rwanda, South Sudan, Sudan, Tanzania and Uganda.

The 2 main tributaries -- the White Nile and the Blue Nile -- converge in Khartoum before flowing north through Egypt and into the Mediterranean Sea.

Around 84 billion cubic meters of water is estimated to flow along the Nile every year.


Ethiopia in 2011 launched construction of the Grand Renaissance Dam on the Blue Nile, roughly 30 kilometers from the border with Sudan.

The $4.2-billion dam is expected to begin generating power by the end of 2020 and be fully operational by 2022.

It will produce about 6,450 megawatts of electricity, making it Africa's biggest hydroelectric dam and doubling Ethiopia's electricity output.


Egypt, an arid nation of nearly 100 million people, depends on the Nile for around 90 percent of its water needs, including for agriculture. 

It says its rights to the Nile's waters are protected by a 1929 treaty which guarantees it a significant quota, and gives it veto power over construction projects along the river.

A 1959 treaty boosted Egypt's allocation to around 66 percent of the river's flow, with 22 percent for Sudan.

But in 2010 Nile Basin countries, excluding Egypt and Sudan, signed another deal, the Cooperative Framework Agreement, that allows projects on the river without Cairo's agreement.


Ethiopia, one of Africa's fastest growing economies, insists the dam will not affect the onward flow of water.

But Egypt fears its supplies will be especially reduced during the time it takes to fill of the 74-billion-cubic-meter capacity reservoir.

The 2 sides need urgently to compromise on a timeline for filling the dam, the International Crisis Group said in a report in March 2019 that warned the issue was a potential flashpoint.

Ethiopia initially wanted it filled in three years so the dam could be operational as soon as possible, the report said. Egypt had asked for 15 years, which would have less downstream impact.

"Waiting until the dam is operational — when its impact on downstream countries is clearer — would raise the risk of violent conflict," the Crisis Group said.
