Not illustrated. 1913 Excerpt: ...of 1906, and all the masonry work of the weir was completed before the flood. The weir consists of a main wall of rubble masonry, grouted with cement, and a downstream wall made in the same way, the space between the two being filled with blocks of dry rubble. On the top of the main core-wall are fitted steel drop-shutters, metres high, worked hydraulically, of which there are 108, in 12 bays. They were constructed by the well-known firm of Messrs Ransomes & Rapier, but unfortunately, being of a novel design, were not all delivered in time for their erection before the flood. Two groups were erected, aggregating 54 metres in length, and were dropped, on the approach of the flood, by the agency of the hydraulic gear without the slightest difficulty. The remainder of the shutters will be erected during the coming summer. The works were ably supervised by Mr Stent. The total expenditure was 28,183, made up as follows: --Labour, sundries, supply of materials, and petty works under 1000....... 9,707 Cement......... 5,510 Supply of ashlar, broken stone, talatat, and masonry work 6,424 Steel shutters........ 3,805 Dredging......... 1,619 Settlement of Mr Daujat in connection with Zifta Barrage subsidiary works.......1,118 Total. 28,183" 1907.--"The balance from 1906 was 4816; of this only 4030 was used to complete the weir.
