P.W.E. New Kowloon
Q 108
(2). The Overflow Dam is situated at the eastern extremity of the reservoir and diverts the overflow into the Lai Chi Kok Valley about a mile below the Kowloon Reservoir.
The total length of the dam is 87 ft. and its maximum height from the lowest foundation level to coping level is 16 ft.; the overflow dimensions being 40' x 3'. The dam is faced on both sides with granite ashlar masonry, whilst the hearting is of 6 to 1 cement concrete.
An 18" draw-off pipe has been provided at a level of 474.00 A.O.D. in order that a direct supply to the Kowloon Filter Beds may be given. By this means the Kowloon Reservoir could also be charged with Shing Mun water should the necessity arise. Immediately below the overflow dam is a masonry gauge wall with a V Notch 2' 6" in height.
(3) The Overflow Channel commences at the Gauge Wall and has been continued down the hillside until a rock bottom was encountered. It is approximately 12 ft. wide by 4' 6" in depth and has a total length of 265 ft. The invert is of 8 to 1 cement concrete stepped to suit the slope. The side walls are of similar concrete and are surmounted by a granite ashlar coping.
By the end of the year the reservoir had been almost filled with water from the Shing Mun River and was found to be practically watertight.
