One of the problems posed is that the Yellow River could not accept such an influx of water at one time. This would require the building of a reservoir at the Lajia Gorge in Maqin County, Qinghai Province. According to Guo's plan, water from this reservoir could be sent to north China to relieve drought conditions as well as keeping the Yellow River flowing during its habitual low-water seasons. The next step would be the excavation of a canal connecting the reservoir to the Qinghai Lake, enabling 60 percent of the water retained to flow into the freshwater Erhai Lake nearby.

Coordination and cooperation between all countries concerned is critical to the project under discussion. An analysis of historical hydrological data indicates that a diversion of 200 billion cubic meters of water will not significantly influence the downstream rivers; instead, it could help reduce flood damage suffered in India and neighboring countries.
After listening to the expedition's report on October 7, 2000, General Zhao Nanqi said: "Even if we do not begin this water diversion project, the next generation will. Sooner or later it will be done."
Voice of opposition
However, in the same year, the Chinese Academy of Engineering (CAE) published its "Strategic Study on Sustainable Development of China's Water Resources in the 21st Century," under the tutorship of academicians Qian Zhengying and Zhang Guangdou.
The CAE report highlighted two potential areas of error in the proposed Great Western Route scheme:
Firstly, the project only plans to channel water into the Yellow River, disregarding all inland rivers in north and northwest China. Furthermore, it is hard to determine whether the Loess Plateau is deficient in water resources. Since the croplands are mostly located on high slopes, the local farmers cannot afford to have the water pumped up from the rivers in the valleys. The report stated: "For the Yellow River's source area, protection is the foremost task. In no way should any arbitrary and impractical decisions be made that would damage this task."
Secondly, northwest China has always been made up of arid or semi-arid zones, while areas south of the Yangtze River are wetlands, each containing their own adaptive ecological environments. To attempt to force a reproduction of the lush southern scenery in the northwest, as promised by the project, would "violate the laws of nature," the report stressed.
Former minister of water resources and supporter of the Three Gorges Dam Project, Qian Zhengying told the State Council in July 2000 that in the near future, there would be no feasibility, technical or economical, for the Great Western Route scheme.
"Grand as Guo's scheme sounds, it may prove to be a castle in the sky," CAE academician Wang Hao said. According to the plan, a 300-meter-high dam would have to be constructed on the Qinghai-Tibet Plateau at an elevation of over 4,000 meters, which is technically impossible. In addition, earthquakes, rock falls, mud flows coupled with the lack of oxygen in high, cold zones will render the work massively difficult.
Wang also thought that Guo had greatly underestimated his plan's cost. "Given the complexity and magnitude of the project, water diversion on the Great Western Route would demand an investment of closer to 1 trillion yuan (US$125.4 billion) than 200 billion yuan," he said.
Wang Shucheng, current minister of water resources and thus a powerful influence on the project, directly referred to Guo's plan as "impractical and fantastical."
"This is purely non-professional advice," he said. "Solving west China's water problem by means of a man-made eco-environment is impossible and will only lead to increased trouble in the future. As for the building of a reservoir at the Erhai Lake, this could well lead to the diverted water being polluted by the saltwater content of the nearby Qinghai Lake."
"The project has shortcomings in its theory, and will not work in reality," he concluded.
Chen Chuanyou, research fellow at the CAS' Institute of Geographic Sciences and Natural Resources Research, highlights another problem area for the project. The biodiversity along the Yalu Tsangpo River valley is an ecological marvel, attained after millions of years of evolution.
"If human activities caused damage to the evolutionary process of organisms in the area, the loss to the whole natural world would be incalculable," warned Chen.
Despite these major flaws with the plan, Guo dismissed Chen's worries as unnecessary. He said that water retained after a dam would inevitably destroy some organisms through flooding but that the major ecological advantages brought about by the Shuotian Canal would surely outweigh its disadvantages.
Besides, Guo added, despite the fragile ecosystem on the plateau, the Yalu Tsangpo River valley is favorable to the growth of wildlife, given its warm and humid climate that brings an abundance of rain each year. Therefore, any harm caused to the local ecosystem by construction work would not be permanent, since the valley benefits from a strong environment in which to rebuild its ecosystem.
According to Guo, following their meeting in Beijing this June, Qiangba Puncog, chairman of Tibet Autonomous Region, thought that the project would benefit rather than harm the plateau's ecological environment.
At a meeting held at the CPC Party School on June 23, Wang Shucheng stated that solutions to the country's water shortage problem lay in developing a water-sustaining society instead of building water diversion projects.
His view was echoed by Wang Hao who regarded trans-provincial water diversion as the last choice, since it is not only costly but may also trigger ecological and relocation problems.
"We are now conducting the South-to-North Water Diversion Project simply because we have no alternative," he said. "But we should bear in mind the lessons of the past and learn to avoid water diversion as we have learnt to avoid war."
Xiangshan conference
Despite the force of the above criticisms, they fell upon deaf ears with Hu Zhenyi, vice general manager of the China Railway Construction Corporation. Hu's company recently completed the construction of the Qinghai-Tibet Railway, which opened to traffic on July 1.
Comparatively to that undertaking, the Great Western Route project is an easy job for the railway engineering corps who have lain down tracks at sites higher than 5,000 meters, he said, adding, "We have gained a great deal of experience in building dams, digging tunnels, protecting local eco-environments and resisting various altitude sicknesses."
He estimated that the project could be completed within six to eight years at most.
Guo Kai (R), initiator of the Shuotian Canal project, and General Liu Zhenhua (L), a warm advocate of Guo's plan.
Given each expert's inflexibility, CAS academician Ma Zongjin called on over 40 experts and officials to attend a conference on June 30, 2005 in Xiangshan (Fragrant Hill) in the western suburbs of Beijing to weigh up the project's options.
"At the meeting, all attendees agreed that water shortage is fast becoming an issue of national security, requiring urgent and immediate action," said Ma.
A strategic perspective, the Great Western Route offers a tentative plan for the solution of the water shortage problem. However, neither side is able to present convincing data based on meticulous field surveys. Ma added that "without accurate data, no one can fairly approve or reject the project."
Guided by the State Council and with joint participation from all ministries and commissions concerned, an investigation mission was called for in the conference's final bulletin, enabling further preparations and deeper study for the project.
"Circumstances permitting, another Xiangshan conference will be held later this year to discuss the program's feasibility as well as to investigate vital issues of international cooperation," said Ma.
