Most of the county is in the upper basin of the Fuchuan River (富川江), a tributary of the He River (Guangxi) (贺江, Hejiang). The Fuchuan is dammed near the southern border of the county. The dam forms the Guishi Reservoir (龟石水库; Gushi Shuiku; 'Turtle Stone Reservoir'), which is used to irrigate agricultural land not only in Fuchuan County itself, but also in Zhongshan County and Babu District to the south.
