Basslink integrated impact assessment statement: Potential effects of changes to hydro power generation. Appendix 7: Gordon River macroinvertebrate and aquatic mammal assessment

Abstract

This report addresses environmental issues associated with instream aquatic fauna of the Gordon River as they pertain to Basslink, focusing on macroinvertebrates and platypus. It describes the current condition of the aquatic fauna of the Gordon River, as well as management issues pertaining to the aquatic ecosystem which result from current operations of the Gordon Dam and power station, and potential future operational conditions that may result under a Basslink 480 MW cable scenario. It then describes possible mitigation measures and their potential to reduce risks to instream biota and habitats under Basslink.
