BEIJING, Oct. 1 (UPI) -- China's most recent hydropower project on the
Mekong River, the Nuozhadu Dam, threatens the ecosystem of the river,
experts warn.

Nuozhadu is the fifth Chinese dam to be commissioned in Yunnan province.

Studies by the Stimson Center, a Washington think tank, say the four
completed Chinese dams "are already altering the river's hydrology and
impeding the flow of nutrient-rich silt that sustains soil productivity,
nurtures fisheries and keeps the sea at bay in the Mekong Delta."

The longest river in Southeast Asia, the Mekong stretches 3,000 miles to
the South China Sea and is home to more than 700 species of freshwater
fish, including the endangered Mekong catfish.

"China's Mekong dams are so remote they receive little coverage in the
Western media," Milton Osborne, a Southeast Asian expert at Lowy
Institute, an international policy think tank, wrote in a blog.

Yet the dams, Osborne said, "will eventually alter the productive
capabilities of mainland Southeast Asia's longest and most important
river, a river vital to the sustenance of the 60 million people of the
Lower Mekong Basin."

The Chinese government claims that 13.5 percent of the water in the
Mekong as a whole flows through China. But Osborne says up to 40 percent
of the river's volume overall sustains the dry season flow for
downstream countries.

Speaking at the Asia-Pacific Economic Cooperation summit in Russia last
month, Vietnamese President Truong Tan Sang warned of increasing
tensions over water.

While not directly pointing the finger at China, Sang said dam projects
in particular were a growing concern, affecting relations between
bordering countries.

"Dam construction and stream adjustments by some countries in upstream
rivers constitute a growing concern for many countries and implicitly
impinge on relations between relevant countries," Radio Free Asia quotes
him as saying.

The first of Nuozhadu's planned nine generators went online last month.
China Huaneng Group, the main investor in the project, said the total
investment could reach $9.6 billion before the project is complete,
Chinese state-run news agency Xinhua reports.

When fully operational, Nuozhadu will produce an estimated 24,000
gigawatts of electricity per year. China Huaneng says energy generated
by the plant will save more than nine million tons of coal annually.

While Nuozhadu is considered a power transmission project from West
China to East China, China Huaneng says it will also supply power to
neighboring countries Laos, Vietnam and Myanmar.

Before the project is complete, about 43,000 people must be relocated.
