The Dashixia Water Control Project in Northwest China's Xinjiang Uygur autonomous region reached a significant milestone on Monday as its dam was successfully capped, signaling the commencement of a new phase in its construction.

The capping of the 247-meter facility, the world's highest concrete-faced sand-gravel dam, happened eight months ahead of the schedule, according to local authorities. A total of 18.9 million cubic meters of materials were consumed in its filling construction.

Launched in September 2021, the project will create a reservoir boasting a capacity exceeding 1.1 billion cubic meters. With a total installed capacity of 750,000 kilowatts, it can generate almost 1.9 billion kilowatt-hours of electricity a year.

Located in the middle and lower reaches of Kumarak River in Aksu region, the project is a major national water-saving and water-supply source.

Upon completion, it is anticipated to offer sustainable water supply to the Tarim River, aiding in the revitalization of its ecosystems. The water allocated to the Aksu River basin will significantly mitigate spring water shortages in its irrigated areas.
