With a total investment of approximately 4.06 billion yuan and a total construction period of 68 months, this project is a key water source project under the "14th Five-Year Plan" for Water Security Guarantee and Yunnan Province's "Revitalizing Yunnan through Water" initiative. It is also one of the 150 major national water conservancy projects and a landmark major water project under the "Two Priorities" construction.
Located in Ninglang Yi Autonomous County, Lijiang City, Yunnan Province, the Nanguaping Reservoir sits in the upper reaches of the Wulang River, a primary tributary of the Jinsha River. The project's objectives primarily focus on irrigation and urban-rural water supply, while also considering the ecological and environmental protection of Chenghai Lake. Upon completion, it will address the urban and rural water supply needs of 203,700 people across 9 townships and 60 villages in Ninglang County and Yongsheng County, with an effective irrigation area of 251,000 mu. The reservoir will also improve the ecological environment of Chenghai Lake by replacing agricultural water intake.
The Nanguaping Reservoir Project is classified as a Class II project, consisting of a main dam and a water conveyance main line. The main dam, an asphalt concrete core rockfill dam, is a Class 1 structure designed to withstand a 100-year flood and checked against a 2,000-year flood. The maximum dam height is 126.6 meters, with a total storage capacity of 118 million cubic meters and a normal water level of 2,299 meters. The average annual water supply is 76.6 million cubic meters. The water conveyance main line includes a 16.5-kilometer diversion tunnel, a 79.84-kilometer main canal, and associated supporting structures. The dam site controls a drainage area of 512 square kilometers, with an average annual runoff of 212 million cubic meters.
Nie Jinhui, Mayor of Lijiang City, attended the mobilization meeting and announced the official start of the preparatory works. Deputy Mayor Lin Zhixiang stated in his address that the project holds overall and strategic significance for addressing Lijiang's water conservancy shortcomings, empowering rural revitalization, and promoting high-quality regional economic development. Pu Chengsong, Chief Engineer of the Yunnan Provincial Water Resources Department, expressed hope that the participating construction units would build the Nanguaping Reservoir into a livelihood water conservancy project characterized by high quality, advanced technology, environmental friendliness, and public satisfaction.
The feasibility study report for the Nanguaping Reservoir Project was approved by the National Development and Reform Commission in January 2026. Feasibility study work for the project began in 2016, and after review by the Ministry of Water Resources in 2020, it was submitted to the National Development and Reform Commission. Evaluation work was completed between 2021 and 2025. Upon completion, the project will effectively optimize regional water resource allocation, enhance the guarantee capacity of agricultural irrigation water supply, improve living water supply conditions in villages and towns, and play a significant role in promoting the sustainable economic and social development of the region.
