Overview
Located in the Yanquan River Gorge, near the Longtouzhai Village Group of Hongcun Town, Lichuan County, Fuzhou City, Jiangxi Province, Longtouzhai Reservoir is a medium-sized water conservancy hub primarily designed for power generation, while also serving flood control and water supply purposes. Built against the scenic backdrop of the reservoir's narrow waters and surrounding forests, the project also gave rise to the Longtouzhai Water Conservancy Scenic Area. The dam features a unique logarithmic spiral thin-masonry double-curvature arch design. Construction of the dam was completed in 1997. The reservoir boasts a long, narrow water surface embraced by dense forests, combining engineering aesthetics with ecological landscape value.

Engineering and Technical Features
• The dam is a logarithmic spiral double-curvature arch dam, standing 90.7 meters high with a 132-meter crest arc length. Its lightweight structure and rational load distribution represent an advanced dam design for its time in China.
• The project includes a pressure water intake tunnel and a powerhouse. It has an installed capacity of 3 × 700 kW, with an average annual electricity generation of approximately 17 million kWh and an annual utilization rate of about 2,800 hours.
• The reservoir features a long, narrow water body extending roughly 7.9 kilometers, playing a vital role in regional flood control, irrigation, and urban and rural water supply, while also enhancing the surrounding ecological environment and landscape.
Surrounding Environment and Visitor Information
• The reservoir is situated in the central section of the Wuyi Mountain Range, within the boundaries of the Jiangxi Yanquan Provincial Nature Reserve (total area: 2,460 hectares) and the Yanquan National Forest Park. The area enjoys high forest coverage and a well-preserved ecological environment. Notable scenic features include Huixian Peak (elevation: 1,355 meters) and Cengping Waterfall, where mountain and water elements create a picturesque harmony.
• The site is located approximately 26–30 kilometers from downtown Lichuan County. Access is mainly via paved roads (asphalt or concrete), making it convenient for self-driving and group travel.
• The Longtouzhai Water Conservancy Scenic Area is open to the public free of charge. It is suitable for activities such as sightseeing, leisure by the water, and science education. However, entry into the reservoir management zone or participation in water-based activities must comply with local water conservancy regulations and safety guidelines.
