Technical Report WRD83001 Viewed at 14:07:22 on 29/07/2010 Page 5 of 64. .~,--~- ,--~ INTRODUCTION The concept of a recreation lake for Alice Springs emerged in the late 1960's. ~1any sites have been considered over the years, from the Hugh River 70 kilometres ,.;est of Alice, to the Ross River 80 kilometres east. Most sites vlere rejected due to factors such as aC8essibili ty, small potential size, or technical factors .. In 1978 the Northern Territory government determined that the feasibility of a recreation lake should be examined as a matter of some priority. Consideration ~las given to several sites with recognised potential, and a recoa~endation made to give priority to further study at the Telegraph Station site on the Todd River. since 1978, investigations have been directed at that site. A number of reports sQ~arising the results of those investigations and confirming the feasibility of a cam at the Telegra9h Station site, were completed in 1979. It was found that such a dam would serve a number of objectives inclUding flood mitigation, recreation, irrigation and tourism. Early in 1980 the firm Dames a!ld Hoare were cormnissioned to carry out an independent envirolliuental study. Thei~ report concluded that the p:coposed lake at the Telegraph Station site is feasible and that it would help fill a significant need in the corr~unity. At the same time a public display of the proposal was hele in Alice Springs. The display generated largely favourable response, with only a few objectron-s. Design for the dam has been carried out using Departmental manpower resources, with a consultant expert on dams being engaged to provide advice and guidance. The Snm.;y Mountains Engineering Corporation was engaged in 1981 to conduct a hydraulic model study comprising two spillwaY options fo!:" ~ne dam. Also during 1981, the Conservation Commission conducted a study to produce a long teLl:l catc~~ent management and rehabilitation program for the Todd River catchment upstream of the proposed impoundment area . .1:ANDYS
