Over the past ten years, the Erhchung flood channel and other flood-prevention works have been completed one after another, and the island has not had major flooding. But because the island lacks a good drainage system, the low-lying areas of the island becomes completely water logged after a big rain, and pedestrians have to slog through the water carrying their shoes.
近十年來，由於二重疏洪道及其他防洪工程陸續完成，社子島未再發生過大水患；但是「小鬼難纏」，一到大雨，由於排水系統不良，低窪地區立刻淹水，行人都得拎著鞋子涉水而行。
