I I I I I I I I I I I I I I I I I I I I With recharge of the Town Basin in Alice Springs being basically dependent on the duration of discharge in the river, the additional attenuation of the dam is likely to lead to greater recharge of the basin. Given the relatively low salinity of this recharge water, this would be expected to have a nett beneficial impact on the Town Basin. Appendix K Hydrology of the Todd River Flood of March 1988 This study is not affected by the revised proposal. Appendix L Channel Improvement Measures for the Todd River in Alice Springs This report is not affected by the revised proposal. Appendix M River Channel Enlargement This report is not affected by the revised proposal. Appendix N Flood Damage Assessment This study is not affected by the revised proposal. Appendix 0 Impact of the Dam on Low Flows in tbe Todd River The "partially full" dam would have little impact on the frequency of low tlows in the Todd River but it would have an impact on the size and duration of the now and the duration of flow. Most flows would be restricted to less than 20ml /s, and would last longer. A flow of 20mJ/s represents OAm of water over the Wills Terrace eauseway. Appendix 0 includes plots of estimated daily flows in the river at Wills Terrace. The "partially full" would not alter the number of "spikes" but most would be restricted to less than 20m'/s. The "full" dam offered potential for releases from the dam during extended dry spills to reduce the stress on tlora and fauna. This would be available to a far lesser degree from the "partially full" dam as it only has a storage when full of 300 ML. Appendix P Multiple Small Catchment Dams With or Without Levees This report is not significantly affected by the revised proposal as the economics of the "partially full" dam would be similar to that for the "fuH" dam. 15
