Plover Cove Scheme
8.67. Work on the remote control of the supply system from Sha Tin was completed, bringing to conclusion all work under Stage I of the Plover Cove Scheme. Stage II works proceeded satisfactorily. The 26 ft. to 30 ft. dia. main tunnel, six miles long, linking Plover Cove with Tai Po Tau was completed and commissioned. Work on the overflow spillway and the two subsidiary dams was substantially completed and work on the upper levels of the main dam at Plover Cove continued.
8.68. The water level of the trapped sea water in the Plover Cove reservoir stood at a level of -27 ft. P.D. at the beginning of April 1967, at which level 10% of the total reservoir capacity remains. Further pumping down to -33 ft. P.D. left the reservoir virtually empty during May.
8.69. A total of 67 tons of biological materials, including 34 tons of marine fish, were removed from the reservoir. Regular surveys of the hydrological and ecological changes in the reservoir were made. 4,200 pounds of fresh water fish were introduced for pilot stocking, the fish showed good growth rates and the stocking was successful.
8.70. The structure of the Tai Mei Tuk pumping station was completed to the underside of the roof and installation of the travelling crane commenced. The construction of the control house was well advanced and finishing work started.
8.71. The construction of the two irrigation dams at Hok Tau and Lau Shui Heung continued.
River Indus Flood Pumping Scheme
8.72. The civil engineering contract for the construction of the pumping station was in the course of being terminated following the contractor's petition for winding-up. Minor outstanding works will be carried out under a separate contract. The erection of a small surge vessel was completed and minor electrical works continued. The installation of five low lift pumps was completed bringing the nominal capacity of all low lift units to 200 m.g.d.
