In the 1840s in California and 1850s in Australia, methods for extracting alluvial gold were developed which involved washing soil and gravel through sluice boxes using diverted streams and other water sources. The waste or tailings were released into the waterways forming large deposits of highly mobile sediment. This 'sludge' as it was generally termed, blocked the stream channels causing flooding and burial of land downstream.[2]
The
Large areas of land were affected by sludge, particularly in Victoria, where a
Ultimately hydraulic sluicing was banned in 1904 as a result of the continuing environmental damage caused to waterways in places such as Omeo, and a Sludge Abatement Board was established to regulate and repair the problem.[1]
