Wong Nai Chung Reservoir Park is a park and artificial lake in Wong Nai Chung Gap, Wong Nai Chung, Hong Kong, located near Hong Kong Parkview. It was formerly Wong Nai Chung Reservoir, a closed reservoir in Hong Kong.
Wong Nai Chung Reservoir was the third reservoir in Hong Kong, built in 1889 in Tai Tam Reservoir Road, Wong Nai Chung. Before closure, it had only water storage capacity of just 27 million imperial gallons (120,000 m3), only 38% of the size of its Pok Fu Lam counterpart. Because of its small water storage capacity, the British Hong Kong Government decided to cease the operations of the reservoir. The reservoir was then converted to Wong Nai Chung Reservoir Park and opened to the public in 1986. It now provides water sports facilities like sampans and boats.
