===Rivers and lakes===
Most of the rivers in Hainan originate in the central area of the island and flow radially in different directions. The [[Nandu River]] in the northern part of the island is {{convert|314|km|mi|abbr=on}} long, and its [[tributary]], the [[Xinwu River]], is {{convert|109|km|mi|abbr=on}} long. Other major rivers include the [[Wanquan River]] at {{convert|162|km|mi|abbr=on}}-long in the east, [[Changhua River]] in the west, and the [[Sanya River|Sanya]] and [[Taiyang River]]s in the south. Evaporation during the dry season around the coastal areas greatly reduces the flow of the rivers.

There are very few natural lakes in Hainan. However, there are numerous [[reservoir (water)|reservoir]]s, the largest of which is the [[Songtao Reservoir]] in the central-north area.
