On November 20, 2000, Sichuan Provincial Electric Power Company invested more than 1.4 million yuan in the implementation of the project of Ying-chi technical transformation - mapping station dam automatic observation system completed and put into trial operation. The dam is a hydraulic structure built in the 1970s. Most of the internal observation facilities buried in the dam have failed, and there are some shortcomings such as manual observation method and large man-made error, which can not meet the technical specifications of concrete dam safety monitoring.
