Keynote Speaker – Professor Susan Lawrence FAHA FSA

Keynote Address: Rivers of Gold , 7pm Tuesday 26/10

Human influence on Australian rivers is nothing new. Recent research has demonstrated that Victoria’s nineteenth-century mining boom dumped a deluge of sand, silt and gravel into local rivers for over 50 years. ‘Sludge’ permanently altered floodplains and river channels all over Victoria. Theimpact was particularly great in the north east where alluvial mining sent millions of tons of sediment into the rivers and dredges churned up lengthy stretches of river bank to depths of up to 40 metres. Downstream communities in the north east led the fight to get sludge out of the rivers. After decades of struggle their efforts resulted in some of the world’s first legislation to restrict mining pollution and remediate former mine sites. That legislation continues to influence mining regulations internationally even though the recent human history of Victorian rivers has been forgotten.

The environmental impact of mining in Victoria is one of the great untold stories of the gold rush and is of lasting significance for communities and natural resource managers today. The story of sludge has implications for river remediation programs, catchment management, public health, the management of cultural heritage and debates about how people and environments interact.
