The High Island Reservoir (Chinese: 萬宜水庫; pinyin: Wànyí shuǐkù; Jyutping: maan6 ji4 seoi2 fu3), located in the far south eastern part of the Sai Kung Peninsula, was opened in 1978 helping to alleviate water shortage problems in Hong Kong. Its water capacity is approximately 273 million cubic metres. The area it occupies was originally the Kwun Mun Channel (官門海峽), which separated High Island from the Sai Kung Peninsula.
Its history starts as a result of the water shutdown by mainland China during the Hong Kong 1967 riots, the government responded with the High Island Reservoir. It was expected to be the same size as Plover Cove. The construction, contracted by an Italian company cost more than HKD $400 million.
The reservoir was designed by Binnie & Partners as a part of the High Island Water Scheme which included pipeworks and other supporting infrastructure as well as the reservoir itself. The reservoir was created by constructing two main dams. One was built at the west of High Island connecting it with the Sai Kung Peninsula at Yuen Ng Fan (元五墳). The other was built in the southeast of High Island, connecting it with the Sai Kung Peninsula near Po Pin Chau, a stack island. Three smaller dams were also constructed in valleys around the reservoir. Aqueducts totalling 5 miles in length were also constructed to transfer water from streams around Sai Kung Peninsula to the reservoir. Construction spanned 10 years from 1969 to 1979. Two roads were created as part of the scheme, crossing over the dams. This enabled visitors to access a very remote and unspoilt area for recreation. Many of the techniques and technology used, like grouting, was cutting edge at the time.
