Disgorging

More on the Three Gorges Dam’s flood control capabilities and its performance in one of the wettest seasons for China since the record-breaking El Niño event of 1997-98. In this report, The Economist concludes the country’s weakened river pulse is “in danger not only from floods but from its flood controls.”

Too many dams to look after

As China continues to embrace a new era of hydropower expansion, demand for dam inspection has outpaced the country’s supply of inspectors, ramping up safety fears for thousands of small- and medium-sized dams in China’s rural areas that have been “ignored”, reports Ecns.cn.

Concern mounts in China over Yangtze diversion project

China’s ambitious South-to-North Water Diversion project officially begins flowing next month and the impacts of the costly geo-engineering giant are starting to be felt in the regions tapped to redistribute water to the country’s parched north. “This project from the beginning has been as controversial as the Three Gorges,” says Probe International fellow and leading Chinese environmental journalist, Dai Qing.

Ten years of the Three Gorges Dam: a call for policy overhaul

An urgent overhaul of Three Gorges’ Dam management policy to enforce relevant regulations is needed to save various endangered species, improve the environment, and encourage economic development, say the authors of this paper. Xiankun Yang and X X Lu of the National University of Singapore discuss what we’ve learned from this controversial megadam over the past decade.

Is the Three Gorges Dam to blame for extreme drought in the Lake Poyang area?

(May 16, 2014) Lake Poyang, the largest freshwater lake in China, has in the past decade suffered record low water levels and its worst drought in 60 years. Although uneven rainfall patterns and industry on the lake are partly behind the decline in volume, the Three Gorges Dam has emerged as a major cause of the lake’s shocking dry-up. On a recent trip to China, Mu Lan, the editor of Probe International’s Chinese Three Gorges Probe news service, explored the link between Poyang’s crisis and the country’s hydro colossus.

Too many masters

(August 20, 2012) A severe test of the Three Gorges dam’s capacity to withstand a major flood peak in July initially showed the mighty dam ready and able. However, downstream areas found themselves at higher risk when floodwaters were released by the dam. Meanwhile, upstream areas are impacted when the dam holds floodwaters back. This article looks at the many pressures, and potential disasters, weighing on the ability of China’s biggest dam to fulfill its design mandate and asks: is July’s flood peak—the biggest test of the dam so far in its nine-year history—just the start?

China’s new mega-dam is a mega-problem

(July 12, 2012) Almost 20 years in the making, China’s Three Gorges mega-dam was declared complete on July 4 when the last of its 32 generators went online, 10 years after the first turbine went into operation. There is no end in sight, however, for costs associated with the vast and controversial project, which remains closer to disaster than triumph.
