Final report prepared by the South Australian Research and Development Institute, Aquatic Sciences, for Commonwealth Environmental Water Office
About the document
The Commonwealth Environmental Water Office commissioned the South Australian Research and Development Institute (SARDI), Aquatic Sciences and partners to monitor the ecological response to environmental water delivered to the lower River Murray during the 2011-12 water year. The main findings were that there was an increased abundance and species richness of native fish compared to drought years (2005-2009) and Commonwealth environmental water contributed to increased base flows in the river channel, increasing hydraulic diversity for native fish. Commonwealth environmental water provided for barrage releases resulted in up to a 70% reduction in salinity levels in the northern Coorong lagoon as well as contributing to the export of salt and nutrients from the Murray Mouth.
