- Abstract
Following an outline of the River Murray Works, a full description of the Torrumbarry Weir and Lock, the most upstream of the weirs and locks on the River, is given. This weir now assures the supply of gravitation water during the irrigation season throughout the Kerang Irrigation District, and at the same time gravitation water is made available for the Cohuna, Gannawarra, Koondrook and Swan Hill Irrigation Districts, all previously supplied by pumping. Also a navigable depth can now be maintained from the weir to the town of Echuca, 52 miles by river upstream, for vessels drawing a depth of 5 ft. of water. The principles of design are enumerated, it being noteworthy that the movable weir is so constructed as to permit of its entire removal from the waterway during the period of high water. The site and method of work are described. The structure was built in an excavation in a bend of the River, avoiding the construction of coffer dams and risks of delays from floods, but involving much additional excavation and the construction of a diversion dam. The diversion of the river through the new work by a novel and interesting: method is described. A description is also given of the plant and plant layout and the handling of materials, as well as of the lock and its operation and the weir and its operation.
