Although not on the scale of the Grand Canal or the Three Gorges Dam, the waterways of Yunnan province are undergoing radical changes. This is especially true in the Three Parallel Rivers Protected Areas. In the name of “development” and “drought prevention”, a new project launched in the province will divert a stunning quantity of water away from the headwaters of the world’s fourth longest river.
Dignitaries and officials attended groundbreaking ceremonies for the Dian Zhong Water Diversion Project (滇中引水工程) on September 30 in Lijiang. Attendees oversaw the initial launch of a program that will divert an estimated 3.403 billion cubic meters of water annually away from the upper reaches of the Yangtze — known as the Jinsha River (金沙江). The ceremony was overseen by Provincial Party Secretary Li Jiheng (李纪恒), while a similar event was held simultaneously in Dali.
The water in question will be funneled southeast through naturally occurring rivers and lakes, first passing near the cities of Dali and Chuxiong before reaching Kunming, Yuxi and Honghe. The intended goals of the project include providing more water for municipal, agricultural and industrial use during times of drought. Of added benefit, according to local media reports, will be the influx of clean water into several lakes suffering from major environmental degradation.
Even though Yunnan as a whole is rich in water resources, the middle of the province is periodically crippled by drought. It is hoped by officials the Dian Zhong Water Diversion Project may avert future water shortages such as the five-year dry-spell between 2009 and 2014 that threatened millions of people and led to billions in lost revenue.
Lakes affected include Kunming’s Dianchi (滇池),Qilu (杞麓湖) near the city of Yuxi, and Yilong (异龙湖) in Honghe Prefecture. Dianchi in particular is an environmental nightmare, and for more than a decade has been covered in a thick, green film of algae rendering it’s waters useless even for industrial use.
The provincial government has repeatedly thrown large sums of money at various Dianchi clean-up and “rehabilitation” efforts. Over the years such measures have included the introduction of invasive plant species, efforts to oxygenate the lake, and theconstruction of water treatment plants along tributary rivers and streams. Nothing has yet showed substantial success.
Two years ago, then-Provincial Party Secretary Qin Guangrong (秦光荣) outlined a new plan for Dianchi, one that would effectively “flush the lake clean” of pollutants and algae with water from the province’s northwest. The Dian Zhong Water Diversion Project appears to be based largely on Qin’s vision, although with a heavily modified and enlarged scope.
The project begins in Shigu (石鼓) — known in China as ‘the first bend in the Yangtze’. From there, an amount of water equivalent to 1,360,000 Olympic-sized swimming pools will be diverted away from the Jinsha River through man-made canals and underground pipelines connected to existing waterways, including the lakes mentioned previously.
Work on the 661-kilometer endeavor — which will not include the construction of any new dams — is expected to take eight years, with “long-term goals” realized by 2040. No cost estimates have yet been made public. Speaking at the ground-breaking ceremony held last month, Yunnan’s acting governor Chen Hao (陈豪), said “This is an exciting time, a time of dreams.”
