Tai Lam Chung Reservoir is a reservoir in Tai Lam Country Park, Tuen Mun District, New Territories, Hong Kong.

As the demand for clean water supplies in Hong Kong grew greater, the construction work of the reservoir commenced in 1952 and was completed in 1957.

Its water storage capacity is about 21 million cubic metres.

[4] In the late 1960s, the government of Hong Kong started to import water from Dongjiang in China to improve the situation of water shortages at the time.

[3] In recent years, this reservoir is also given the nickname "the Thousand Island Lake of Hong Kong" due to the similarity in sceneries.
