Hydraulic mining became the largest-scale, and most devastating, form of placer mining. Water was redirected into an ever-narrowing channel, through a large canvas hose, and out through a giant iron nozzle , called a "monitor", the extremely high pressure stream was used to wash entire hillsides through enormous sluices.
It is estimated that hydraulic mining methods lost between 30% 50% of the gold that was liberated from the deposit. In addition, many of the drain tunnels were also used as the primary locations for the placement of elongated sluice box recovery systems.
