Abstract

This symposium describes the planning and design of the Upper Tumut Works of the Snowy Mountains Hydro-electric Authority. The Upper Tumut Works broadly consist of the various projects which will be used for the diversion and regulation of waters into Adaminaby Reservoir and Tumut Pond and thence through Power Stations T1 and T2 in the valley of the Upper Tumut River.
The main storage for this development will be formed by the construction of the 380-ft. high Adaminaby Dam on the Eucumbene River which will impound over 3 million ac.-ft. of water. The Eucumbene-Tumut Tunnel, some 14 miles in length and 21-ft. in diameter, will convey water from Adaminaby Reservoir to the Tumut River at Tumut Pond and thence through the 320,000-kW. Power Station T1 and the 280,000-kW. Power station T2. As described in this paper, the waters of the Tumut River can be diverted back through the Eucumbene-Tumut Tunnel to Adaminaby Reservoir for storage.
Other projects of the Upper Tumut Works are the Tooma-Tumut and the Murrumbidgee-Eucumbene Diversions.
The Tooma-Tumut Diversion will comprise a dam over 200-ft. high on the Tooma River and a tunnel about 9 miles in length which will divert water from the Tooma River to either Tumut Pond for immediate use for the generation of hydro-electric power or, via the Eucumbene-Tumut Tunnel, to Adaminaby Reservoir for storage. The Murrumbidgee-Eucumbene diversion will consist of a diversion dam on the Murrumbidgee River and a 9-mile tunnel leading the Murrumbidgee waters direct to the uppermost reach of Adaminaby Reservoir.
Adaminaby Reservoir is at present being constructed for the Authority by the Public Works Department of New South Wales and it is not described in this paper. The Eucumbene-Tumut Tunnel and Tumut Pond Dam are both under construction by Kaiser-Walsh-Perini-Raymond Joint Venture, Contractors to the Authority, whilst the T1 Power Station is being constructed by a group of French contractors. The turbines for Station T1 will be supplied by the English Electric Company, the generators by A.S.E.A. of Sweden and the transformers by A.C.E.C. of Belgium.
Under an Agreement made in 1951 between the Australian and United States Governments, the U.S. Bureau of Reclamation has already prepared designs and specifications for Adaminaby Dam, Eucumbene-Tumut Tunnel, Tumut Pond Dam and T1 Pressure Tunnel, and is at present preparing designs on certain aspects of Tooma Diversion and the T2 Project. Various Authority Engineers who have undertaken training courses at Denver with the Bureau have assisted in this work.

Part 1: 'Investigation and planning' (by Campbell, D. E. pp.1-8), describes the investigation and planning of the entire Upper Tumut Works.

Part 2: 'Design' (by Pinkerton, I. L. pp.9-18), on the design of the Upper Tumut Works, is limited to the works for which contracts have already been awarded, namely, the Eucumbene-Tumut Tunnel, Tumut Pond Dam, T1 Pressure Tunnel and T1 Power Station.

Part 3: 'T1 Power Station layout and plant' (by Bray, A. N. G.; and Frost, A. C. H. pp.18-27), outlines the T1 Power Station Layout and describes the plant which will be used in connection with the station.
