The Plover Cove scheme involved the raising of the main and two

subsidiary dams, the construction of a small saddle dam at the Tai Mei Tuk

peninsula, and the installation of 64 concrete syphone on the existing spillway,

thus increasing the maximum storage level from 27 to 44 feet.

The

Raising of the three dams comprised the majority of the work.

crest length of the main dam now measures 6,800 feet and that of the northern

and southern subsidiary dams are 650 and 690 feet respectively.

The syphons, which work by suction to discharge excess flood water

into the sea at a much higher rate than a conventional spillway, will reduce

the amount of freeboard needed to contain flood water build up in the reservoir

and thus reduce the cost and time of construction.

main dam are boxed for collection.
