The flow of water carves a stone valley in the forest. It nourishes a plain where cities are built, to carry humanity and history. We are amazed by the divine works of nature, but we also have to borrow the natural resources from the land. Shihgang Dam locates at a crossroad of nature and humanity. It has an important function as a water reservoir management center. So we name it "Valley", with a hope to bring the ideal balance between environmental protection and development to people's attention.
