Feicui Dam (traditional Chinese: 翡翠水壩; simplified Chinese: 翡翠水坝; pinyin: Fěicuì Shuǐbà; Pe̍h-ōe-jī: Húi-chhùi Chúi-pà) is a double curvature concrete arch dam on the Beishi River in Shiding District, New Taipei, Taiwan, forming Feicui Reservoir (翡翠水庫). The dam is located in Shiding District, New Taipei City, and is usually misunderstood as the principal water source for the Greater Taipei area (In fact, the principal water source for the Greater Taipei area is Nanshi River. Feicui Dam, by contrast, is the water source in reserve). The name of the dam and reservoir translates as "emerald lake", in reference to the pure quality of the water. The area is managed by the Taipei Feicui Reservoir Administration. Public access is heavily restricted in order to protect water quality, which is among the highest of Taiwan's reservoirs.
