Unlike the Three Gorges project, the Yellow River dam received a favorable reception from bankers and environmentalists.

A report issued in November 2008, declared that two thirds of the Yellow River is heavily polluted by industrial waste and is unsafe to use.
It consisted of hundreds of settlements along the Yellow River and Wei River regions, and stretched across the northwestern plains from Shaanxi province in central China to Gansu province in the west. The Sanmenxia Dam was supposed stop chronic flooding on the Yellow River.
Today, the Yellow River is above the landscape for much of its last 800 kilometers (500 miles) to the sea and the river continues to rise at an alarming rate of four inches a year.
Four billion tons of waste water---10 percent of the river's volume---flows annually into the Yellow River.
The Yellow River is regarded at the cradle of Chinese civilization and culture. In existence from around 5000 B.C. Many of the survivors made their way back to land near the land they were displaced from. The Sanmenxia (Sanmen Gorge) Dam is a 106 meters (348 feet) high and 713 meters (2,339 feet) long. For example, the river Huai He, a major river in central China and the traditional border between North China and South China, traditionally cut through north Jiangsu to reach the Yellow Sea. The Peiligang culture is the name given by archaeologists to a group of Neolithic communities in the Yi-Luo river basin in Henan Province, China. of the east, distinguished for its black pottery. These sediments are mostlt deposit in the slower lower sections of the river, elevating the river bed and creating the famous "river above ground" Such material is made available in an effort to advance understanding of country or topic discussed in the article. Within months, Shaanxi's capital, Xian, faced the real threat of inundation in the next major flood. Most agree that Jiahu was part of the Peiligang culture, pointing to the many similarities. This region includes northwestern Illinois, southwestern Wisconsin and southeastern Minnesota. The Yellow River travels through major industrial areas, China's major coal producing region and huge population centers. Known as the mother river by all the Chinese people, the 5,464-kilometer (about 3,395 miles) Yellow River is the second longest in China after the Yangtze River.The headwaters of this mighty river lie in Kunlun Mountains in northwestern Qinghai Province. In accordance with Title 17 U.S.C. Sixty-three water pumps had to be shut down, including some in Jinan, the capital of Shandong Province. The reservoir behind the Soviet-designed Yellow River dam built at Sanmenxia in 1960 silted up after only two years.
The muddy Yellow River flowing through China – the country’s second longest after the Yangtze – could today be the clearest it has been in 500 years, according to a new study. Li Xiaoqiang of the Yellow River Conservancy Commission told AFP, “Everyone wants more water, the dams want water for electricity, the industries want water to increase production, the farmers want more water for irrigation and cities need water for daily living. + More than 80 percent of the Hai-Huaih Yellow River basin is chronically polluted. The large amount of mud and sand discharged into the river makes the Yellow River the most sediment-laden river in the world. Repair work took several decades. These important discoveries prove that the Jiahu culture played an important role in the development of Chinese civilization." It supplies water to 155 million people, or 12 percent of the Chinese population, and irrigates 18 million acres — 15 percent of China's farmland. The forest consists of 8,900 acres of hardwood and coniferous forest and is comprised of 6 units. roughly northeast of the Tibetan Plateau; 2) the Middle Section at the Ordos Loop; and 3) the Lower Section in the North China Plain. A lot of water is wasted. The situation wasn’t that different in Europe. The old path of the Huai He is now marked by a series of irrigation channels, the most significant of which is the North Jiangsu Irrigation Main Channel, which channels a small amount of the water of the Huai He alongside south of its old path into the sea. Peter Lee wrote in the Asia Times, Improperly sited and designed, the dam's reservoir silted up almost immediately.
During a 1958 flood sediment levels were measured at 35 pounds per square foot, causing the river surface to become “wrinkled. The cultivation of rice, for example, was unique to Jiahu and was not practiced among the villages of the main Peiligang group in the north. In August 2006, new laws were passed to better manage and reduce fights over the Yellow River. Their circular pi and square "ts'ung" were concrete realization of a universal view, which saw the heavens as round and he earth as square.
Instead it slowed the rivers current, causing silting on a massive scale and increasing the likelihood of flooding.
