Murrumbidgee River System, it can be used to irrigate a large area of arid but fertile plain country or, if required, to be taken under the Great Dividing Range into the River Murray to the extensive Murray Valley Irrigation area. Blizzards and frozen roads are not usually thought of in the Australian context but Project Manager, Boyd C. Paulson, and his crews have their share of this kind of weather. The location is within sight of Kosciusko which, at 7, 314 ft., is the highest mountain "Down Under". The Project is surrounded by ski lodges, chair lifts and all of the recreational attractions of a thriving winter playground. The Utah crew promise themselves that they will make full use of these opportunities - when the job is done. Burnie Breakwater The construction of an island breakwater for the Marine Board of Burnie in Burnie, Tasmania, construction of a reinforced concrete cellular structure 1,611 ft. in length. The formation is made up of 16 caissons, each 100 ft. long, 50 ft. wide, and 55 ft. high. The Breakwater wall is of concrete, 20 ft. high on the seaward side of the caissons. Preliminary work involved removal by dredge of 15"0, 000 cubic yards of material to provide access channels, an outfitting basin and a basin for a temporary breakwater. The quantities involved were as follows: concrete: 50,000 cubic yards; Reinforcing steel: 5,100 tons; Weight of each caisson: 4,400 tons, Sand and gravel fill: 130,000 cubic yards; Mean depth of water on site: 39 feet. The contract value of this project at the end of fiscal 1963 was $5,107,963.
