Yellow River

• 1. Geological Origins And Formation

  ›

  The Yellow River first formed sometime during the Late Miocene, Pliocene or Pleistocene epochs. This geological event occurred as a result of the Tibetan Plateau being uplifted. Zhenbo Hu and colleagues documented rapid fluvial incision along the Jinshaan gorge over the past 1.2 million years due to tectonic extension. The river's source lies in the Bayan Har Mountains near the eastern edge of the Yushu Tibetan Autonomous Prefecture. Source tributaries drain into Gyaring Lake and Ngoring Lake on the western edge of Golog Prefecture high in the Bayan Har Mountains of Qinghai. These two lakes have capacities of 4.7 billion cubic meters and 10.8 billion cubic meters respectively. They are among the largest plateau freshwater lakes nationwide at elevations over 4,000 meters above sea level.

  According to traditional Chinese historiography, the Xia dynasty originated on its banks around 2100 BC. Sima Qian's Shiji record states that the Xia were founded after tribes around the Yellow River united to combat frequent floods in the area. Historical documents from the Spring and Autumn period indicate the river flowed considerably north of its present course during that era. After passing Luoyang, it ran along the border between Shanxi and Henan Provinces before emptying into Bohai Bay near present-day Tianjin. Another outlet followed essentially the present course until 602 BC when the river left these paths and shifted several hundred kilometers to the east. Sabotage of dikes became a standard military tactic during the Warring States period. The Yellow River valley served as the major entryway to the Guanzhong area and the state of Qin from the North China Plain.

  In the 2,540 years from 595 BC to 1946 AD, the Yellow River has been reckoned to have flooded 1,593 times. It shifted its course 26 times noticeably and nine times severely. Among the deadliest events was the 1887 flood which killed anywhere from 900,000 to 2 million people. A Republic of China era 1931 flood killed an estimated 1,000,000 to 4,000,000 people. On the 9th of June 1938, Nationalist troops under Chiang Kai-shek broke levees holding back the river near Huayuankou in Henan. This operation caused what Canadian historian Diana Lary called a war-induced natural disaster affecting an area covering 250,000 square kilometers. The flood took some 500,000 to 900,000 Chinese lives along with unknown numbers of Japanese soldiers. In 1642, Ming governor of Kaifeng broke dikes attempting to destroy peasant rebels under Li Zicheng but destroyed his own city instead. The resulting flood and ensuing famine are estimated to have killed 300,000 of the city's previous population of 378,000.

  In 1954, the People's Republic of China announced its General Plan to Fundamentally Control Yellow River Flood Disasters and Develop Yellow River Waterworks. Construction began in earnest in 1957. From the 1970s to the 1990s, dry-up trends accelerated with the river failing to reach its mouth for approximately 180 days per year in the 1990s. In 1997, the Yellow River did not reach the sea for 226 consecutive days. On the 12th of August 2024, the Yellow River Water Conservancy Committee reported continuous flow for 25 consecutive years since unified water flow regulation implementation in 1999. Over these past 25 years, the main stream supplied more than 543.6 billion cubic meters of water including 1.464 billion cubic meters of ecological replenishment. Several dams have been built including Sanmenxia Dam which opened in 1960 and Xiaolangdi Dam completed in 2001. The seven largest hydro power plants had total installed capacity of 5,618 MW as reported in 2000.

  ›

  The Yellow River basin is home to more than 160 native species in 92 genera and 28 families including 19 endemic species found nowhere else in the world. However, due to habitat loss and pollution many natives have declined or disappeared entirely. In the 2000s only 80 native fish in 63 genera and 18 families were recorded compared to earlier counts. Introduced fish rose from one species recorded in the 1960s to 26 species by the 2000s. An annual fishing ban has been implemented since 2018 covering the entire Yellow River basin from the 1st of April to the 30th of June each year. A total ban on natural fish fishing began in upper reaches starting the 1st of April 2022 until end of 2025. On the 25th of November 2008, Tania Branigan reported severe pollution made one-third of China's Yellow River unusable even for agricultural use. The Yellow River Conservancy Commission surveyed over 4,000 kilometers of river in 2007 finding 33.8% registered worse than level five criteria.

• 6. Etymology And Cultural Symbolism

  ›

  When the Yellow River was still somewhat clear it was simply referred to as 'the river' with Old Chinese pronunciation. Observations at Yumenkou gorge indicated the river changed to muddy sometime between 367 BC and 165 AD according to chronicles records. Alternative names like 'murky river' appeared in 145 BC while '(muddy) yellow river' was attested in 429 AD respectively. The name Yellow River fully replaced Murky River by the end of Tang dynasty for unclear reasons. In Mongolian it is called Khatan gol meaning queen river. The Tibetan name translates to River of the Peacock. Traditional belief held that the Yellow River flowed from Heaven as continuation of Milky Way. During Yongle Emperor reign, the river running clear was reported as good omen alongside appearance of qilin giraffe brought by Zheng He ships in 1414. The provinces of Hebei and Henan derive their names from the Yellow River meaning North of River and South of River respectively.
