After 13 years of immense physical effort and technical ingenuity, China yesterday put the finishing touches to its controversial Three Gorges dam, the world's largest hydropower project.
The official completion of the dam was marked by a short ceremony at the site broadcast live on state television, which touted it as an "important historic moment."
"I can announce to the Chinese people ... that the Three Gorges dam is completed," Li Yong'an, manager of the Three Gorges Construction Company, said shortly after the last load of cement was poured onto the top of the dam.
The 2,309m-long, 185m-high block of concrete across the Yangtze is meant to control floods and generate electricity for a power-hungry nation, but for many Chinese it is about much more than that.
"The Three Gorges dam is excellent proof of what Chinese can accomplish," said Cao Guangjing, vice president of the China Yangtze Three Gorges Project Development Corporation. "This project will serve to inspire the Chinese people."
Although the final tonne of concrete has been poured, the immense structure will still not be fully operational for another two years.
The last generators need to be installed, and work still needs to be done on the ship lift that, together with a ship lock, will allow ocean-going vessels to navigate the vast reservoir that is filling up behind the dam.
Although it is not all over yet, many of the engineers felt it as if a page had been turned and a chapter in their personal lives was nearing conclusion.
"I started in 1993, fresh from university, and I have been here ever since," said engineer Wang Zilin, 43, from Zhejiang Province. "It's been my whole life. I even found my wife here."
Even while work was being carried out on the dam, engineers and laborers were reminded that flood control was one of the main reasons behind the giant project.
In 1998, a devastating flood on the Yangtze uprooted millions of families and killed more than 1,500 people. Two much larger disasters in the 1930s each claimed more than 140,000 lives.
Nevertheless, critics continue to argue that silt build-up and other problems mean the dam will fail to provide the hoped-for flood relief.
Opponents also see damage to the environment, ruin to China's heritage and misery to local residents forced from their homes for the project.
However, harnessing the power of China's mightiest rivers is a dream harbored by generations of Chinese.

It is no longer just the stuff of poetry. On the left bank, 14 sets of 700-megawatt turbine and generator units are already in operation.
On the right bank, another 12 700-megawatt units are under construction.
With a capacity already equivalent to Itaipu on the border of Brazil and Paraguay, which is now the world's largest operating hydroelectric dam, the Three Gorges will eventually overshadow all others.
A new tender process is due to be held by the end of the year for adding a new power station with another six 700-megawatt generators, underground on the right bank.
