The vastness of the building site was at first overwhelming for the young Ethiopian mechanical engineer.
Hundreds were already digging the foundations in tough conditions for what is now Africa’s largest hydro-electric dam, straddling the Blue Nile. The dam will help electrify the country as well as provide power to the region.
Moges Yeshiwas was 27 when he arrived in that remote corner of western Ethiopia in 2012, eager to gain valuable experience in his profession. The completion of the project is set to change his nation, but it also changed his life.
On Tuesday, Prime Minister Abiy Ahmed formally launched the Grand Ethiopian Renaissance Dam (Gerd), hailing it as “the greatest achievement in the history of the Black race”.
Abiy, alongside Kenya’s President William Ruto and Djibouti’s Ismail Guelleh, unveiled a plaque before powering up the turbines.
The dam will help electrify the country as well as provide power to the region.
It wall stretches 1.78km (1.1 miles) across a valley and stands 145m (475 feet) high – it is constructed with 11 million cubic metres of concrete. It has created a huge reservoir, called Lake Nigat, which means dawn in the Amharic language.
The dam’s construction on a Nile tributary, which provides most of that great river’s water, was controversial with downstream countries. Diplomatic tension with Egypt cranked up and there was even talk of conflict.
But for Ethiopia the Gerd has become a symbol of national pride and, in Abiy’s view, it has placed his country firmly on the world stage.
“Watching the dam’s progress day by day was deeply satisfying. I came seeking employment, but somewhere along the way, it stopped feeling like just a job. I grew attached to the project, worrying about its future as if it were my own.”
There were challenges.
“Lengthy separation from family was difficult,” he told the BBC. Mr Moges could only go home – a 400km-drive away in Bahir Dar – twice a year.
The dam site’s remoteness and the at times extreme heat – with temperatures sometimes hitting 45C – also presented issues. Plus, the working hours were long.
“Our shifts ran from 7am to 7pm, with only an hour’s break for lunch. Then we handed over to the night crew, because the work had to continue around the clock,” Mr Moges said.
His job was to make sure the building work was structurally sound and construction standards were maintained.
The Gerd project was a rare unifying force as the Horn of Africa country has been rocked by political violence and ethnic strife in the past decade.
While some, like the engineer, worked directly on the dam, millions of other Ethiopians were, literally, invested in it.
People from all walks of life contributed to building the dam through donations and the purchase of government-issued bonds.
Despite claims by US President Donald Trump that Washington financially supported the dam’s construction, Addis Ababa maintains it was fully funded domestically.
On a personal level, Mr Moges, now 40, was also “very proud to be part of it”.

Several fundraising campaigns were held that saw members of the public contribute multiple times.
Clinical nurse Kiros Asfaw was one of those.
Despite being from the Tigray region, which was blighted by a two-year civil war, he contributed when he could to the dam’s construction ever since the plans were first announced in 2011.
He says he bought government bonds more than 100 times – though he had to pause his purchases during the conflict, when basic services, including banking, were suspended in Tigray.
Mr Kiros’ motivation was rooted in remarks made by Ethiopia’s late Prime Minister Meles Zenawi, who oversaw the beginning of the project, that all Ethiopians must come together in backing the dam.
“I promised myself to do everything I could to help it through the finish line,” the father-of-five told the BBC.
Now, with all the turbines working, thoughts turn to what difference the power can make to Ethiopia.

At full capacity it should generate 5,100MW of power – more than double what the country produces without the dam and enough to supply tens of millions more homes in the country. That is however dependent on the infrastructure being in place to carry the power to different parts of the country.
Water and Energy Minister Habtamu Ifeta told the BBC that nearly half of the country’s 135 million people do not have access to electricity.
“That is what we want to reduce now in the coming five years. Our intention is by 2030 at least 90% of our nation should get access to electricity,” he said.
