Egypt depends on the Nile for almost all of it's water. "Studies were not adequate
for a project of this scale." the presidency said.


"Ethiopia has not thought hard enough about the impact of its ambitious dam project
along the Nile, Egypt said on Sunday, underlining how countries downstream are concerned about its impact on water supplies.
Centerpiece to the plan is the Grand Renaissance Dam being built in
the Benishangul-Gumuz region bordering Sudan.
Now 21 percent complete, it will eventually have a 6,000 megawatt capacity,
the government says, equivalent to six nuclear powerplants."

Sounds like the project for Three Gorges dam in China; rush to completion without consideration of the consequences to the people or land.

A dam can only reduce water flow when it is filling up, after that it has zero impact on net flow, it just moderates the extremes.  The risk is that once the dam is filled it can be siphoned off and diverted for their benefit, (farm irrigation, new cities, etc.).  It's the siphoning off for other uses, not the dam itself, that causes shortages down stream, similar to the Colorado river in the US.

My guess is that Ethiopia has studied it quite well, to their own advantage! :<)

Of course Egypt has it's own Aswan dam, forming lake Nasser.
