Dayingjiang

Dayingjiang

Daying river is a tributary of the upper reaches of Irrawaddy River. It originates from the south foot of Gaoligong Mountain. Daying river is a rare super development in the world. Three large-scale hydropower stations have been built in a short distance of 2km. The dam of Daying River II is 0.7km downstream of the dam site of Daying River I Hydropower Station, while the dam site of Daying River III hydropower station is only 1.3km away from the dam site of Daying River II. A rare flower in the history of human hydropower development!!! The remaining two under normal development are the Dayingjiang IV hydropower station and the Taipingjiang I Hydropower Station in Myanmar. The storage levels of hydropower stations at all levels of Daying River are 788m, 735m, 692M, 585m and 255m respectively, and they flow into the Irrawaddy River at the altitude of 105m.

On December 17, 2014, the Ministry of housing and urban rural development (MOHURD) announced the inspection results of law enforcement in 2014, which indicated that Dayingjiang scenic spot was not up to the standard and was criticized and ordered to rectify within a time limit
