The Feicui Dam ( Chinese 翡翠 水庫 , Pinyin Fěicuì Shuǐkù ), also rewritten as Feitsui (literally ' emerald dam'), is a dam in the Shiding district of the city of New Taipei in the north of the island of Taiwan . Its reservoir , the area of which extends over the districts of Shiding and Pinglin and which feeds from the dammed Beishi River , is the second largest reservoir in Taiwan and of great importance for the drinking water supply in the greater Taipei area . It is also used to generate electricity. In contrast to the second large dam in northern Taiwan, the Shimen Dam , located further to the south-west, the Feicui Dam is not open to the public and is therefore not a place for recreation or excursions.
history
The planning for the construction of the dam began in 1971 and lasted eight years. The construction work began in August 1979 and lasted until June 1987. In the course of the damming of the Beishi River, some natural valleys were flooded and their population was relocated. The dam is named after one of the valleys.
Impact on the environment
Since the valleys affected by the flooding were only sparsely populated, the resettlement of the population was relatively easy, but many natural beauties and landscapes that had previously been popular excursion destinations disappeared. In addition, the flooding destroyed the habitat of the rhododendron kanehirai, a rare species of rhododendron that only occurs in Feicui and has not been found growing wild since then.
