Abstract

This report details the supplementary aquatic fauna survey conducted in Southampton Pool (Blackwood River) in November 2013. The study replicates the initial survey conducted by the authors for the Water Corporation that determined the aquatic fauna within the pool, identified likely risks that the proposed construction of a subterranean pipeline at the upstream margin of the pool may have on these fauna, and recommended strategies and actions that could be taken to minimize those potential impacts identified. The need for the current survey arose due to a major bush fire that burnt the site in February (12‐15th) 2013 that may have caused changes to the prevailing fauna thereby probably rendering the initial survey as inappropriate to assess risks to the fauna. The initial comprehensive aquatic faunal survey (Appendix 1) specifically recommended repeating that survey given the confounding influence the bush fire may have had on the aquatic fauna.

Therefore, the current study aimed to determine the prevailing fauna in the pool prior to the construction phase of the pipeline project being conducted. It then aimed to assess whether notable changes in the fauna had occurred compared to the initial survey. Finally, it aimed to review and potentially refine our previous recommendations to ensure they were still appropriate for the management of the aquatic fauna of Southampton Pool prior to, and during, pipeline construction to mitigate its potential ecological impacts.
