Three Gate Gorge Dam (Sanmenxia) June 1/1998 A Lamentation for the Yellow River by Shang Wei "A Clear Yellow River"
According to the 1949 preliminary report, controlling the perennial floods on the lower reaches of the Yellow River required that a number of dams and reservoirs be built. However, the question of where these dams and reservoirs would be built remained unanswered. In the report, Wang asserted that there were three possible sites between Shan County and Mengjin City - Three Gate Gorge, Balihutong, and Xiaolangdi. This proposal marked the beginning of serious planning for a dam at the Three Gate Gorge. In summer 1950, Fu Zuoyi, then minister of water resources, headed a delegation to the Soviet Union to study water resource development. The delegation included Zhang Hanying, then vice minister of the Ministry of Water Resources, and Zhang Guang, who would later play a critical role in promoting the construction of the Three Gate Gorge dam. Upon the delegation's return, Fu Zuoyi delivered a report on developing water resources to the State Council. In tone and in substance, Fu argued for a thorough and comprehensive approach to developing the Yellow River. He urged that the banks and dikes of the Yellow River be reinforced, that agriculture and forestry policies be integrated to improve soil conservation on both the mainstream and the tributaries, and that preparations be made for the construction of a reservoir between Tongguan pass in Shaanxi and Mengjin to block flood waters and sedimentation in the tributaries. The emphasis was clearly on damming the Yellow River's tributaries, since, according to Fu, building a dam on the mainstream posed serious political, economic, and technical problems.3 Although Wang Huayun's Yellow River Commission had, in its 1950 report, made note of the scale of resettlement required if the Three Gate Gorge site were chosen, it did not favor damming the tributaries as Fu suggested. The commission claimed that there were too many of them, that the flood control benefits were unreliable, and that the cost was prohibitive. Thus, yet another commission study was prepared for the project, this one more positive than its 1950 predecessor. The new study made sensational claims about the prospective flood control, electricity generation, and irrigation benefits of a dam at the Three Gate Gorge site and proposed the construction of a large dam with a normal pool level of 350 meters that would both store flood waters and block sedimentation behind the dam. At first glance, it seemed that this plan would put an end to flooding in the lower reaches caused by the river's high sediment load.4 But where to put the sediment? The answer, of course, was in a reservoir large enough to store it. In spring 1952, Wang Huayun accompanied a group of Soviet engineers to the Three Gate Gorge site. The Soviets, who had been building grandiose dam projects in Siberia for decades, made fast friends with the members of the Yellow River Commission.5 Out of this visit a high dam was once again proposed for the Three Gate Gorge area. But the problems related to resettlement and the inundation of farmland remained, and dam opponents drew attention to them, stalling the project. Less than a year later, the project began to gain momentum again. In October 1952, Mao took a tour of the Yellow River and uttered a line which resonated with both sides in the controversy over whether to build the Three Gate Gorge dam. He said: "Work on the Yellow River must be carried out well." But what was to be carried out well? A large dam? Smaller dams on the tributaries? Both sides tried to claim Mao's words as support for their views, but, in the end, the pro-dam side won the struggle. Shortly thereafter, the Yellow River Commission rejected, once and for all, the idea of building a series of smaller dams on the tributaries and insisted on the large-scale Three Gate Gorge dam. Wang Huayun personally submitted a report to Mao to this effect The dam opponents were reduced to trying to block the project purely on financial terms. Deng Zihui, the head of the CCP's Rural Work Department, did his part by authorizing a "miracle" budget of a mere ¥500 million, which would pay for the resettlement of only 50,000 of the 600,000 to one million relocatees who would be displaced by the dam. Dam critics then peppered supporters with questions about how they planned to properly resettle people with so little money. By forcing pro-dam officials to admit that the budget was woefully inadequate, the anti-dam forces hoped to kill the project. But the plan failed. When asked about resettlement, dam supporters would quickly shift gears and ask, "Well what about flood control?" As Zhou Enlai commented: "They seemed to believe that if the Three Gate Gorge dam was not built, the lower reaches of the Yellow River would be immediately devastated by flood."6 Deng Zihui had no choice but to try to personally persuade Mao to oppose the project.7 He told Mao that he basically agreed with the measures for flood control. But rather than build the large dam at the Three Gate Gorge, he argued that during the First Five-Year Plan [1953-57],8 the government should build two reservoirs at Zhichuan and Mang hill near Luoyang. Then, after five or ten years, the country would have the resources and technical expertise to build large-scale reservoirs and deal with large numbers of relocatees. Although this was not exactly what Mao wanted to hear, he could not refute what Deng was saying. And so, once again, the project was postponed. In January 1954, a contingent of Soviets known as the Yellow River Planning Soviet Experts Group came to Beijing at the invitation of the Chinese government. From February to June 1954, a 120-member investigation group composed of both Chinese and Soviet experts surveyed the area from Liujia Gorge to the mouth of the Yellow River. They concluded that Three Gate Gorge was a good site for a dam project. This opinion played a decisive role in the decision to launch the project, and Deng Zihui was powerless to oppose it. During the survey, in April 1954, the central government decided to entrust the design of the dam and reservoir to the Soviet experts. Their design, delivered eight months later, recommended a 350-meter normal pool level and a reservoir with a 36 billion cubic meter storage capacity. The primary purposes of the dam would be to:
In its conclusion, the Soviet design report suggested that the project would bring about enormous benefits. However, two serious problems remained: First, the project would submerge 2.07 million mu of land and force 600,000 people from their homes. And, second, because of the accumulation of sediment in the reservoir, the dam would only last twenty-five to thirty years. Thus, debate over the project shifted from whether it should be built at all, to how to reduce the accumulation of sediment in the upper reaches. The pro-dam forces called for extensive soil conservation in the watershed, a proposal that would ultimately play a decisive role in the final decision to launch the project. In a "technical task report" produced by the Chinese contingent of the joint Soviet and Chinese experts' group, new data on sedimentation was released: By 1967, the Chinese claimed, the sediment delivery to the reservoir would be reduced by 50 percent, and after fifty years it would be reduced by 100 percent.10
The Soviet contingent of the group could not tolerate such bombast and urged caution in estimating the benefits of soil conservation measures. They concluded that "by 1967 the sediment would be reduced by 20 percent and in fifty years time by 50 percent.11 Despite the Soviet experts' concerns, however, the project was now well on its way. Later, the CCP decided to entrust further design work for the dam to the Leningrad branch of the Soviet Power Stations Water and Electricity Design Institute, but stipulated certain points in the design. The Soviet designers were told to:
Amid all of the enthusiasm and chaos there appeared two intellectuals who would play key roles in the evolution of the project. One was a professor from a renowned university, and the other was a young college graduate. They disagreed with the plans to build a high dam at the Three Gate Gorge site and calmly explained their views to the top decision makers. But they were ignored. When I met with them in 1991, their lowly political and professional status had not changed for over thirty years. The professor was named Huang Wanli, and the young engineer, Wen Shanzhang. Huang Wanli was the son of the CCP's ally Huang Yanpei. At the time of this controversy, Huang Wanli was a professor in the Department of Hydrology at Qinghua University, China's premier technical institution. Not yet fifty years old, he was a well-educated and experienced engineer. After graduating from Tangshan Communications University in 1932, Huang became a structural civil engineer. But after flooding of the Han River [a tributary of the Yellow River] in 1931 and the collapse of the Yellow River dam in 1933, many young people became interested in studying hydrology.16 In fact, a survey of Chinese engineers conducted after the Han River flood revealed that all of China's hydro engineers were civil engineers. There was not a single hydrological engineer among them. This meant that the engineers could design dams, but knew nothing about river hydrology. Huang therefore decided to make hydrology his specialty. In January 1934, he went to the United States. Assuming that floods occurred after rainstorms, he decided to major in meteorology. After completing a master's degree at Cornell University, Huang shifted his focus to Geology for his Ph.D. at the University of Illinois. After receiving his doctorate, Huang set out to visit every major hydro project in the United States, which he followed with a four-month internship at the Tennessee Valley Authority [now the United States' largest public utility]. On his return to China, Huang was appointed a hydro supervisor for the Economic Committee of the Kuomintang government. Later, he became an engineer and survey director for the Bureau of Hydrology in Sichuan Province. During the War of Resistance against Japan [1937-45], he surveyed the Min, Wu, and Jialing rivers on foot. In 1947, he became director of the Gansu Province Hydrological Bureau, and, in 1949, was appointed as a consultant to the Northeast Hydro Bureau. According to Huang: "The study of geography and geology was an eye-opening experience that made me realize that the structural theories of civil engineering were inadequate for solving the problems of floods. Dam projects are built on rivers and they change the dynamics of water flow which, in turn, cause changes in the riverbed. When I first returned to China, the field of geology had yet to be established. Ten years later, I had walked 3,000 kilometers and collected rich data on various aspects of hydrology and information on the harnessing of rivers."17 After hearing about the Soviets' December 1954 Design Report, and the 1956 Revised Design which followed, Huang Wanli made a submission to the Yellow River Commission, in which he raised doubts about the entire planning procedure. Although Huang believed that dams could effectively adjust the flow of water in a river, he felt they were bound to destroy the natural flow of sediment. He also felt that dire consequences would follow from the policy of keeping the lower reaches of the Yellow River "clear" and free of sediment. Huang argued that top soil on the banks of the river should remain where it was, while dirt or sediment in the riverbed must flow continuously. The idea of purposely accumulating sediment behind a dam was wrong, he argued. It was an attempt to fiddle around with the laws of nature.
Huang also argued that the accumulation of sediment would limit the reservoir's lifespan and, furthermore, that no one had bothered to consider what would happen to the upper and lower reaches when the dam was no longer in use. As a result of these and other concerns, Huang categorically opposed building large-scale dams on the mainstreams of major rivers. If a dam had to be built on a mainstream, Huang insisted that sediment be flushed out of the reservoir as much as possible [the exact opposite of the plan to eventually create a "clear Yellow River" downstream of the Three Gate Gorge dam]. To achieve this, Huang felt that large sediment sluice gates should be installed at the base of the dam. Wen Shanzhang is a hydrologist who studied in the Soviet Union with the Soviet delegation but disagreed with their proposal for the Three Gate Gorge dam. Instead, he suggested a lower dam (with a 335-meter normal pool level) and a small reservoir that would release flood waters and flush sediment. This dam would generate less electricity, but it would also cause less inundation, require the resettlement of fewer people, and be much cheaper to build.18
In June 1957, two months before the launch of the project, over 70 experts took part in the "Symposium on the Three Gate Gorge Pivotal Hydro Project."19 Wen Shanzhang was the first to speak. Rather than suggest a few simple modifications to the official plan, Wen advocated the construction of a smaller dam, as described above. Above all, Wen argued against adopting a "grandiose" approach to the dam's construction.20 Wen opposed the Soviet design and argued that it was not necessary to build a large-scale project like the Three Gate Gorge dam for irrigation alone. Moreover, he felt that eastern and northern Henan should develop their own irrigation networks and that irrigation needs in other areas could be met by building a series of smaller dams. He also explained that a smaller dam could successfully control floods and lower the cost of the dam by ¥450 million. It would also lower the number of relocatees to fewer than 150,000 and reduce the amount of land to be submerged to only 500,000 mu.
Zhang Shouyin (an engineer in the Hydrology Bureau of Shaanxi Prov- ince) chimed in on the issue of resettlement, explaining Shaanxi Province's opposition to the large-dam design. "When the water level is raised from 350 to 360 meters," he noted, "the number of relocatees increases sharply from 437,000 to 735,000."22 Zhang therefore suggested that the normal pool level not exceed 350 meters; otherwise, he warned, sediment accumulation would lead to floods that would threaten the city of Xi'an. Forced Reconstruction One year after the project was launched, six million square meters of earth had been moved, and 30,000 cubic meters of reinforced concrete had been poured.25 But Shaanxi Province still opposed the dam proposal and continued to request changes to it. In late 1958, after the disastrous Chengdu Conference [where rapid development of water resources was approved along with an initial proposal to construct a dam at the Three Gorges on the Yangtze], Zhou Enlai, Peng Dehuai, and Xi Zhongxun visited the Three Gate Gorge construction site. Both Peng and Xi had considerable political clout with the Northwest Bureau of the CCP, and it was understood that once they approved the project Shaanxi Province would have no say. Although Zhou Enlai made no public statements about the project during this site visit, his doubts and skepticism were evident. One day, as charts and diagrams were being set up in a meeting room, Zhou walked in and asked why none of the charts included a dam design based on the 335-meter normal pool level [the design proposed by Wen Shanzhang]. The engineer in charge responded that the 335-meter proposal would create a reservoir insufficiently large, to which Zhou, in turn, responded: "The only thing you people understand is large-scale this and big that."26
At a subsequent meeting held at the site, debate was heated. The Shaanxi delegation gave impassioned speeches requesting a lower normal pool level, and Zhou tried to support them. Xi Zhongxun proposed a compromise - a 360-meter design, an actual height of 350 meters, and effective water storage at 340 meters. The compromise was accepted, meaning that the pro-dam group's desire for a 360-meter dam was not completely rejected but that the normal pool level would, in reality, be only 340 meters.
Despite the reconstruction, however, sediment continued to move toward the upper reaches. At the April 1962 third session of the Second National People's Congress, delegates from Shaanxi Province proposed lowering the normal pool level to below 315 meters and opening all of the locks to release flood waters and flush out sediment. In other words, they were proposing that the Yellow River flow freely, and that the dam become a run-of-the-river design. But destroying the dam was a difficult proposition at best, so Zhou Enlai convened a series of meetings to come up with an alternative plan. Between 1965 and 1968, the project was rebuilt again. The normal pool level was reduced to 315 meters, almost doubling the amount of water (and, hopefully, sediment) that the dam could release per second. But above Tongguan pass, the sediment continued to build up. The Yelluw River simply would not behave itself. Eventually, the dam, which was now full of holes, was able to release enough water and flush out enough sediment to balance further deposition, at least temporarily. In 1978, five turbines, with an installed capacity of 250,000 kilowatts, were installed at the dam. (The original design called for 1,160,000 kilowatts.)
Despite all of the problems with electricity generation and sedimentation, many felt that the effects of inundation and resettlement were even more serious. Based on the 360-meter design, 3,330,000 mu of land was to be submerged and 900,000 people were to be resettled. When Zhou Enlai had the normal pool level essentially reduced to 335 meters, the effects were reduced significantly - only 856,000 mu was submerged and 318,900 people resettled.30 But many were resettled for naught - the project was such a failure that some relocatees' land was never submerged.31 Moreover, the mass of accumulated sediment created vast swaths of new land. In the late 1980s, thirty years after the dam was built, sedimentation once again became a problem. This time the favored solution was the construction of another dam - the Xiaolangdi - in the lower reaches of the Yellow River. The new reservoir would have a total capacity of 12 billion cubic meters of water, would control floods, and would help reduce sedimentation in the lower reaches of the river for up to twenty years. After that new measures would have to be adopted. During the thirtieth anniversary of the Three Gate Gorge dam the following refrain was repeated over and over:
The Three Gate Gorge and Three Gorges Dams In November 1994, the Three Gorges dam on the Yangtze River was officially launched - thirty-seven years after the Three Gate Gorge dam had been started. What are the similarities between the two dams? Both structures are on the mainstreams of the most important rivers in China. Both are record-breaking, large-scale projects designed to control floods downstream. Both are said to provide "huge economic benefits" through electricity generation: Originally, it was claimed that the Three Gate Gorge dam would fulfill one-third of the country's electricity needs, and now it is said that the Three Gorges dam will provide one-tenth of the national supply. Both dams are supposed to facilitate navigation on their rivers. Both projects require submerging vast tracts of farmland and relocating large numbers of people: 410,000 in the case of the Three Gate Gorge and 1,200,000 in the case of the Three Gorges. The Three Gate Gorge dam destroyed 1,000-year-old cultural relics and antiquities from the civilization of central China. The Three Gorges dam will destroy relics from an even earlier period, the Ba culture.
In both cases, provinces in the upper reaches of the two rivers suffered: Shaanxi in the Three Gate Gorge and Sichuan for the Three Gorges. Representatives from Sichuan pleaded to the government just like their counterparts in Shaanxi, but in both cases their opinions were systematically ignored. Both projects faced similar sediment problems. In the case of the Three Gate Gorge, sediment threatened the city of Xi'an while sediment trapped in the Three Gorges reservoir will threaten Chongqing. Both cities are provincial capitals and important industrial cities. Catchy slogans have been created to help deal with the dams' respective sediment problems - "soil conservation" was the clarion call of the Three Gate Gorge, just as "store clean water and flush out sediment" is the proposed solution for the Three Gorges. Authorities claimed that both projects were "demanded by the people" because they were approved by the National People's Congress. And both were funded by the state as part of the planned economy. As a result, no matter how large the disaster, no one will have to take personal responsibility for their failures. The potential social and political impacts of both projects were ignored. In each case, the head engineers (Wang Huayun for the Three Gate Gorge project and Lin Yishan for the Three Gorges) were the Party's "red specialists." Because of their red backgrounds, they feared nothing. Both were blindly confident and pursued the vanity of dictatorship. In both cases, the dam's opponents - Wen Shanzhang in the case of the Three Gate Gorge and Huang Wanli in both cases - proposed smaller dams as the most rational alternative to large-scale dams and giant reservoirs. Huang's predictions for the Three Gate Gorge dam all came true. For the Three Gorges project he cautioned that it is absurd to build a dam on the mainstream of such a sediment-laden river. He also warned the authorities not to ignore local interests. Let's not forget that it was the Railroad Protection Movement in Sichuan Province that triggered the 1912 Republican revolution. The Three Gate Gorge dam now has to be operated according to Wen Shanzhang's original instructions from 1957. What will happen in the case of the Three Gorges?
Huang Wanli, who has now passed away, will never see the Yangtze River blocked up. But what about Wen Shanzhang? Will he one day be forced to write the book on what went wrong with the Three Gorges dam project?
4 In the early 1950s, the Yellow River carried about 1.3 billion tons of silt through the Three Gate Gorge annually. See Smil, The Bad Earth, p. 44.
8 The major slogan of the First Five-Year Plan was "Let's be modern and Soviet." See Riskin, China's Political Economy, p. 53. 10 1954 Report by Chinese Contingent, "Huanghe Sanmenxia shuili shuniu sheji jishu renwushu" (Technical Task Report on the Yellow River Three Gate Gorge Pivotal Hydro Project) (n.p., n.d.). While soil conservation measures such as reforestation can significantly reduce the suspended sediment conveyed by the river into the reservoir, it is a practical impossibility to reduce the amount by 100 percent. All rivers, even in the best protected watersheds, convey appreciable amounts of sediment during natural floods. 11 1954 Report by Soviet Contingent, "Key Points of the Initial Design of the Three Gate Gorge Project" (n.p., n.d.). 12 This grandiose plan for the utilization of the Yellow River had as its centerpiece the construction of 46 separate dams on the river to impound water for the generation of electricity, expansion of the irrigated areas in the river basin, and increased navigation. The dam at the Three Gate Gorge was to be the largest of the 46. See Smil, The Bad Earth, p. 45. 13 Cao Yingwang, Zhou Enlai yu zhishui, 1991.

Many Chinese hydrologists agreed with this suggestion but no one dared say anything in support of the American views. The Three Gate Gorge power station would be the largest in Asia and many comrades, out of patriotism, were anxious to launch this project. Also, no one dared disagree with the Soviet experts and support the Americans even if the issue was a purely technical one. 25 Wen Shanzhang, Huanghe Sanmenxia gongcheng huigu yu pingjia (Recollections and Evaluation of the Three Gate Gorge Dam Project on the Yellow River).
