The Longtang Dam (龙塘大坝), also known as Longtang Reservoir and Nandu River Dam, is located on the Nandu River at Longtang, Hainan, China.
When the water level is low enough this concrete dam serves as a river crossing for vehicles and pedestrians. The dam has a normal water level of 7.7 metres. At 11.5 metres, an alert is issued. When the dam is closed, large metal doors are lowered at each end to prevent access.
The dam also has hydro electric stations on both banks.
