CONCLUSTON In consideration of all the ma~~ers raised in this subrnissio~ and the reports referred tOt it is submitted that: (a) A dam at the Telegraph Station site would be technically feasible. (b) The dam would offer substantial flood mitigation benefits to the extent that the project is economically justifiable on .flood mitigation grounds alone. ) h '" 1 d ., ~ Al . c:.. . th t . (c T.!e ~_oo rlSX ~O lee ~prlngs lS so serlOUS a, In the event that the Telegraph Station site is not available, alternative da~ site(s) on the Todd River or l"CS tributaries should be immediately considered for the development of flood mitigation works; hoy/ever, any such sites will offer infe~ior recreation potential compared with Telegraph Station site. (d) Most if not all of the points of technical concern raised in submissions can be satisfactorily ansr,vered on the basis of current knowledge. (e) Notwithstanding that ~~original people and some Europeans may have real concern over the proposal, tne course taken by the Department of Tra:1sport and Works in leading to the recol11..menda tior. on the Telegraph Station site is defended: All work has been oerformed in a professional manner; steps taken to consult the Aboriginal people (and indeed the public at large) during the early stages of the project were reasonable and taken in good faith. (f) All other potential damsites within a 60 kilometre radius of Alice Springs ~re either technically non-feasible, or would offer a smaller size lake on average, or would cost more than the Teleg=-aph Station si te ~ From the recreation vie'.v point, the Ildj arabada si te on Jay Creek offers t1:.e only reasonable alte2:"native. (a) ~ None of the other potential damsi tes vlOUl.d. nave any flood mltlgatlOn benefit for Alice Springs exceDt other possible sites on the Todd River. The most promising such site, at Junction Creek, may be capable of attentuating floods comparably with the Telegraph Station site, but it would be more expensive and offer only about- half the area for recreation, comparee. it'lith Telegraph Station site.
