APPENDIX D (a) (b) MATTERS RA TSED TN SUB"lISSIONS ON THE 'l'ET.EGRl,PH STATION SITE Eight submissions were received following the publication of the Feasibility Report. Of these I five express~d views totally in opposition to the lake; another tHO raised points of concern but were not totally opposed . Additionally, environmentalist Harry Butler sent the Environmental RevieH to the Chief Minister. in general support of the lake, but raised concern. comments on Butler was points of In June 1981 f the Central Australian Conse:cvation Council sent a submission to the Chief Minister. The main points raised by the above submissions are listed below, Hith COIT~ents on each: Concern that, by infereDce from the behaviou~ of arid zone Haterholes during times of drought, the lake will dry up in drought times. There is an obviously inadequate collation and assessment of hydrological records (eg. flood reoords) . The hydrological studies conducted during the feasibility study were very thorough and probably based on more data than most darns already built in Australia. It is pointed out that ever.. in times of drought 1:De Todd River flows at least once in almost every year. The hydrological studies were based on 25 years of Todd River floH records (including one severe drought) and 105 years of rainfall record. Concern that the feasibility report (Transport and Works / 1979) presents a "prevailing hopefulness" and is highly speculative~ One example given is the statemer..t nan annual draft of one million kilolitres could be prOVided with virtually zero 9robability of failure!l. 11 :~.NDYS Such corr~ents reflect a misunderstanding of the amount of data used and analysis carried out. This is probably because the feasibility report itself contains little hard data details of data and analysis undertaken are contained in the associated reports (particularly the Hydrology Report) or, in the case of some minor aspects, on internal files. An attempt to incorporate an honest conservatism in the documents has been interpreted in some cases as an indication of considerable doubt.
