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. It is a concrete dam with electricity generation stations on both the east and west banks. The normal water level at the dam is 7.7 metres. At 11.5 metres, an alert is issued. When the water level is low enough, this dam serves as a river crossing for vehicles and pedestrians.
At 12:00, August 19, 2016, after Tropical Storm Dianmu brought heavy rains, the water level at the dam reached 13.35 metres, a ten-year high. This prompted a yellow alert indicating that water levels for the Nandu River downstream of the dam would be around two metres higher than normal.
