Abstract: By 2018, 722 reservoirs (including power station reservoirs) will be built, with some of which had been built and are still partly under construction in Xinjiang (including Xingjing Production and Construction Corps), China giving a total storage capacity of nearly 295×108 m3. These reservoirs have effectively enhanced the efficiency of regulating and utilizing water resources and played an extremely crucial role in irrigation, water supply, flood control, power generation, tourism, etc. In line with the working principle given by the Ministry of Water Resources, “compensating the shortcomings of water conservancy projects and enhancing the supervision of water conservancy industry”, plans to address the problem of the imbalanced and insufficient utilization in water resources are proposed. These include building dozens of large and medium-sized mountain reservoirs, improving the information digitization management of dams, providing drinking water and industrial water against the background of satisfying ecological water, maximizing the benefits, and ensuring the safe operations of reservoir. This paper presents the work in terms of the flood risk analysis under climate changes, several key technologies used for dam construction, the replacement of plain reservoirs with mountain reservoirs, the concerns about river health and ecological regulation, reservoir dredging and its capacity enhancement, the digitization and intelligent dispatch of reservoirs, and extending the operating time of reservoirs.
