Core Viewpoint - The completion of the dam construction for the Chongqing Zhaodu Reservoir marks a significant milestone in a major national water conservancy project aimed at enhancing flood control, water supply, and irrigation capabilities in the region [2][5]. Group 1: Project Overview - The Chongqing Zhaodu Reservoir is part of 172 national water-saving and supply projects and 150 major water conservancy projects approved by the State Council, focusing on flood control, water supply, and irrigation, while also incorporating ecological and power generation functions [2]. - The total investment for the project is 10.123 billion yuan, with a total construction period of 60 months [2]. - The reservoir has a normal water storage level of 375 meters and a total capacity of 201 million cubic meters [2]. Group 2: Benefits and Impact - Upon completion, the reservoir will enhance flood control capabilities for the downstream Chongqing Qijiang urban area, providing an additional annual water supply of approximately 17.9 million cubic meters and increasing irrigated land by 170,000 acres [2]. - The project will also improve irrigation for an additional 65,000 acres, ensuring water security for districts such as Chongqing Nan'an, Qijiang, Banan, and Jiangjin [2]. - The reservoir will utilize ecological flow and surplus water for power generation, with a power station capacity of 12,000 kilowatts and an average annual electricity generation of 44.94 million kilowatt-hours [2]. Group 3: Construction Details - The dam structure is a concrete-faced rockfill dam with a maximum height of 104.5 meters, and the completion of the dam filling to a height of 376.3 meters is a critical step for the project [5]. - The quality of the dam filling is crucial for its ability to store water, control floods, supply water, and generate power, directly affecting the stability and safety of the dam's operation [5]. - Current construction includes the spillway, drainage tunnel, and water conveyance tunnel, with plans to strengthen construction management for the foundation of water storage by 2027 [7].
