history
The project started on September 28, 1993, impounded on April 16, 1997 and passed the completion acceptance on June 11, 1999.

In October 2003, the tunnel diversion project of Lianghui reservoir was completed and put into operation. Through the joint operation of Lianghui reservoir and Lubu reservoir, and through the optimization of the operation scheme of Lianghui reservoir, the water level of the reservoir in non flood season and Mei flood season was determined to be 45.00 m, with the corresponding storage capacity of 24.76 million cubic meters; the water level in Taiwan flood season was 41.50 m, with the corresponding storage capacity of 19.3 million cubic meters; the water supply capacity of Lianghui reservoir with 90% guarantee rate was increased from the original The water supply to Yuyao is 25 million cubic meters per year and to Cixi is 20 million cubic meters per year.
It passed the first safety appraisal in 2004. The reservoir basin covers an area of 35.06 square kilometers. The main stream lianghuidaxi belongs to Yaojiang River System in Yongjiang River Basin, flowing into Yaojiang River from south to north, with a main stream length of 11.11 km. The reservoir is designed according to 50 year return period flood and checked according to 2000 year return period flood. The design flood level is 46.90m, and the corresponding storage capacity is 27.99 million cubic meters; the check flood level is 48.86m, and the corresponding storage capacity is 31.52 million cubic meters. The average annual water supply capacity for many years is 20.78 million cubic meters.
