Shek Lei Pui Reservoir, Reservoir in Kam Shan Country Park, Sha Tin, New Territories, Hong Kong

Shek Lei Pui Reservoir is a man-made lake inside Kam Shan Country Park, in the Sha Tin area of the New Territories in Hong Kong. It sits between two dams, and a small historic valve house built in the early 20th century stands at the center of one of them.

The reservoir was built between 1923 and 1925 as part of Hong Kong's early efforts to secure a reliable water supply for its growing population. Its dams and valve house were later listed as Grade II historic buildings because of their role in the city's early infrastructure.

The reservoir takes its name from Shek Lei Pui Village, whose residents were moved to Hin Tin in Tai Wai and to Kwai Chung when the valley was dammed. In 1963 Master Ha Kinh began teaching Luk Tung Kuen, a set of 36 exercises, at the water's edge; practitioners still gather here in the morning.

The reservoir lies in the southwestern part of Sha Tin District, New Territories, reached via Tai Po Road through Kam Shan Country Park; the Kowloon reservoirs are commonly treated as one group. The two dams and the central valve house are Grade II historic buildings, so walkers cross them on foot. Morning visits coincide with the Luk Tung Kuen exercise sessions held by the water.

Since 1963, a group of people has gathered here at dawn to practice Luk Tung Kuen, a traditional exercise routine that resembles Tai Chi. Visitors who arrive early in the morning may find this practice still taking place by the water, often without realizing what they are watching.
