The Longyangxia dam with the Longyangxia hydropower plant is located in the Chinese province of Qinghai on the Qinghai-Tibet plateau at an altitude of 2600 m on the Yellow River (Huanghe). The purpose of the dam is hydropower generation and flood protection.

The hydropower plant is located on the border of Gonghe and Guinan counties and about 1.5 km from Longyangxia Gorge. With four turbines, each with an output of 320 MW, a total of 1280 MW is generated.

The maximum storage space of the reservoir is 27,419 (also indicated as 27,630) million m³, with full back-up it is 24,700 million m³. The highest congestion destination is at 2607 m above sea level. NN.

Construction work began in 1978. Damming of the reservoir began in October 1986 and commissioning took place in 1989.

The barrier structure is a weight arched concrete wall. It has an arc length at the crown of 396 m; In total, the top of the wall is 1277 m long. The concrete volume of the main structure is 1.53 million m³, a total of 3.16 million m³.

At that time this dam was the highest dam in China; today it is surpassed by the Ertan dam and several even larger ones are under construction. Another large dam on the upper Yellow River is the Liujiaxia Dam and in the lower reaches the Sanmenxia Dam .

In addition, a solar park with an output of 850 MWp was built near the dam , which as of January 2017 was the most powerful solar park in the world.
