Hydraulic mining was and remains controversialIt produced great wealth from the soil of California yet damaged the land in such a way that the scars will remain for eons Great hillsides were denuded of soil by streams of water which boggle the imagination and the sediment which was washed away filled the streambeds of the valleys below.
The invention of hydraulic mining is generally attributed to Edward E Matteson near Nevada City California in February of 1852 May Philip 1970 Within 5 years of this invention the mining engineers of the Sierra Nevada had constructed five thousand miles of ditches and flumes to supply the water needed to power the monstrous hydraulic.

From the 1850s to the 1880s more than 15 billion cubic yards of goldbearing placer gravels were processed by hydraulic mining in Californias northern Sierra Nevada region The resulting debris caused property damage and flooding downstream In 1884 the Sawyer Decision prohibited discharge of hydraulic mining debris to rivers and streams in.

Folks here is a highly technical and scientific piece entitled Hydraulic Mining in California by Taliesin Evans It is regarded as a California industry deriving its origin and growth from the peculiarities of the auriferous placerformations in the State.
Hydraulic Mining was a gold recovery method that was used during many of the gold rushes around the world during the 1800s It was used extensively in Californias Mother Lode county during the famous gold rush there One of the problems that the early California gold miners faced with basic placer mining was the amount of manual labor that was required to process the gravels.
Hydraulic mining was born in 1853 when a man named Edward Mattison increased the water pressure by adding a nozzle to the hose Waste ore and gravel tailings were piled on creek banks or dumped into streams leading to the Yuba River.
