Feitsui Dam (, also Feicui Dam) is a double curvature concrete arch dam on the Beishi River in northern Taiwan. The dam is located in Shiding District, New Taipei City, and is one of the principal water sources for the Greater Taipei area. 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 Feitsui Reservoir Administration. Public access is heavily restricted in order to protect water quality, which is among the highest of Taiwan's reservoirs. ==History== The dam was proposed in the 1970s during a period of severe drought in northern Taiwan. The reservoir site was located on the Beishi River, which joins with the Nanshi River to form the Xindian River which flows through New Taipei City. A dam built here would hold back water during the wet season, when the flow in Nanshi River alone is enough to meet water demands, and release water to augment supplies as needed during the dry season. This dam site was considered favorable because of good soil and forest conditions of the upstream watershed; at the time human development consisted mainly of tea plantations. The quality was much better than the watershed behind Shihmen Dam, the other major water source for greater Taipei, which has suffered crippling sediment issues due to deforestation. In order to preserve the watershed, the Taiwan government evicted many residents in upstream areas. Although the Dam is located in New Taipei, construction was funded by Taipei City, in order to provide water to the capital. Construction began in August 1979 and was completed in June 1987. The dam cost NT$11.4 billion to construct. Today about 46 percent of the water is delivered to Taipei City and 54 percent is used in New Taipei. The service area incorporates about 6.3 million people–a quarter of Taiwan's population. In 2014, the Feitsui Reservoir supplied a total of 344.5 million cubic metres (279,300 acre feet) of water for municipal and industrial uses, or about 944,000 cubic metres (249 million gallons) per day. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Feitsui Dam」の詳細全文を読む スポンサード リンク
