Ethiopia has begun diverting the Blue Nile as part of a giant dam project, officials said on Wednesday, risking potential unease from downstream nations Sudan and Egypt.

But Sudan dismissed any conflict, saying there were agreements with both Ethiopia and Egypt concerning sharing the waters of the Nile.

The $4.2 billion (3.2 billion euro) Grand Renaissance Dam hydroelectric project had to divert a short section of the river — one of two major tributaries of the Nile — to allow the main dam wall to be built.

“To build the dam, the natural course must be dry,” said Addis Tadele, spokesman for the Ethiopian Electric Power Corporation (EEPCo), a day after a formal ceremony at the construction site.

The river is being shifted about 550 metres (yards) from its natural course, Addis said, but stressed that water levels would not be affected.

“There is no problem with the river levels,” he said.

The first phase of construction is expected to be complete in three years, with a capacity of 700 megawatts.

Once complete, the dam will have a capacity of 6,000 megawatts.

Both Sudan and Egypt, arid nations that rely heavily on the Nile for water, particularly for agriculture, are extremely sensitive about projects that could alter the flow.

However, EEPCo insists the project will not impact downstream needs, claiming the dam will provide “highly regulated outflows” by reducing floods at peak times and providing more water during otherwise low flows.

In Khartoum, the foreign ministry said Sudan would not be affected by the project, stressing in a statement that there are agreements and consultations between Sudan, Egypt and Ethiopia.

“Sudan respects the agreements to cooperate with those two countries (Egypt, Ethiopia) in matters that concern sharing the waters of the Nile and sharing mutual revenues,” the Sudanese foreign ministry said.

The dam project, in Ethiopia’s northwestern Benishangul-Gumuz region near the border with Sudan, was launched in April 2011 by late prime minister Meles Zenawi.

Funding is being raised publicly, with the state raising funds locally, and no external financing has been provided.

Ethiopia is constructing a series of dams to produce hydroelectric power for both domestic consumption and export.

EEPCo has plans to establish transmission lines to neighbouring countries, including Sudan, Kenya and Djibouti.

One of Ethiopia’s deputy prime ministers, Demeke Mekonnen, officially launched the river diversion on Tuesday, alongside EEPCo chief Mihret Dibebe.

When completed, the dam wall will stretch almost 1.8 kilometres (about one mile) in length and 145 metres (475 feet) in height.

  1. Lake Tana is approximately 84 kilometres long and if we say the GERD is bigger than Lake Tana then the 1.8 Kilometres that was mentioned as the length of the new dam is wrong.

  2. do not measure it by km, go ahead ethiopia
