Abstract:Established in May 1915, Tai'er Zhuang Sluice Hydrological Station has a history of over 100 years, which is an important hydrological station in Zhongyun Canal. During its century- long development, the station has accumulated a large amount of hydrological data, recording information such as the establishment and changes of the hydrological station, observation items and data, important events and contributions, as well as honors. These data, preserved in the form of archives, have become a witness to the history of the hydrological station and play an important role in the construction of the hydrological station.
