Lower Shing Mun Reservoir [1965- ]

The AMO write:

Lower Shing Mun Reservoir (下城門水塘) was built between 1961 and
1965 as part of Stage I of the Plover Cove Water Scheme and built to back up
the Shing Mun (Jubilee) Reservoir 城門(銀禧)水塘. It was built on the site of
an old wolfram (鎢) mine opened by a European company at various points in
the slope of Needle Hill. The Reservoir was built for storing the overflow from
Shing Mun (Jubilee) Reservoir and is connected to the Kowloon Group of
Reservoirs and the Sha Tin Treatment Works (沙田濾水廠).
