INTRODUCTION In October 1990, the Power and Water Authority issued an Environmental Impact Statement (EIS) for the flood mitigation dam on the Todd River at a site known as Junction Waterhole, 9km north of Alice Springs. The EIS looked in detail at both "full" and "empty" dam options and concluded that a dam which permanently stored water up to EL658 was the best option. Design and construction of the Alice Springs flood mitigation dam commenced in February, 1991 on the basis of a Certificate issued by the Aboriginal Areas Protection Authority. Following subsequent objections by some groups within the Aboriginal community, the Federal Minister for Aboriginal Affairs intervened to prevent further work on the site and the Aboriginal Areas Protection Authority withdrew their Authority Certificate for the construction of the dam. The principal objection to the construction of the dam related to the permanent inundation of the sacred site known as Tnyere-Akerte located on the Todd River approximately lkm upstream of the proposed dam. The l'.'T Government decided to pursue an option of a "partially full" dam as a compromise which maintains a high level of Hood mitigation at minimal additional cost but which does not permanently inundate the Tnyere-Akerte site. Many aspects of the original EIS remain valid for the "partially full" dam. The purpose of this report is to discuss those aspects of the "partially fuli" dam which would now differ from the "full" dam covered by the EIS. The aspects which do not differ are not repeated in this report. The original proponent of the project was the Power & Water Authority. As a result of restructuring this has changed and the proponent is now the Northern Territory Department of Transport & Works. 1
