Wushantou Reservoir, located between Chiayi and Tainan, is one the popular scenic spots of southern Taiwan. Surrounded by mountains, it is formed by more than thirty tributary streams. Since it resembles a piece of coral from a bird's-eye view, it also is called Coral Lake.
烏山頭水庫是台灣南部兼具山水之勝的風景區之一，位於嘉義、台南兩縣的交會處，四面環山，由三十餘條支流匯合而成，由高空俯視，狀似珊瑚，故又名珊瑚潭。
