Competing Interests

The work reported in this manuscript was partly funded by Melbourne Water. Melbourne Water is a corporation owned by the Government of Victoria, with statutory responsibilities for the management of rivers and other waterways of the Melbourne region. They fund “public good” research to further the environmental sustainability of their operations. In the area of sustainable waterway management, both TDF and CJW have, over the last 5 years, undertaking consultancies, sat on advisory committees and provided other unpaid advice to Melbourne Water. Part of the University of Melbourne research fellow position held by CJW is funded by a Melbourne Water research grant. This relationship and funding source does not alter the authors' adherence to all the PLOS ONE policies on sharing data and materials. The authors have no other competing interests.
