The director of the Taipei Water Department, Kuo Jui-hua, points out that while the water storage capacity of Shihmen Reservoir is only one half that of Feitsui, its surface area is twice that of Feitsui. Also, upstream soil conservation work is difficult, which exacerbates the consequences of any disaster like that caused by Aere.
