Qingshuigou was originally a small river at the mouth of the Yellow River. From 1964 to 1976, the Yellow River entered the sea from the Diaokou River. Because of the Yellow River's "one diversion in ten years" rule, the Qingshuigou was surveyed in advance and determined to be the Yellow River again. The alternate river course was rerouted, and preparations were made for up to 9 years. On May 20, 1976, the Yellow River was introduced into Qingshuigou by manual diversion. Since then, the Yellow River has entered the sea from Qingshuigou.
The Qingshuigou river course was originally planned to travel for 12-14 years, and its life expectancy will expire in 1990 at most. With the economic development of Shengli Oilfield and the Yellow River Delta, the demand for stable river courses has become stronger and stronger. Thanks to the continuous efforts of Chinese water conservancy workers The exploration, the continuous improvement of technical level, the stable flow of Qingshuigou to this day, has created a miracle in the history of the Yellow River.
