Hydraulic Mining in California. By Craig E. Crouch, Rocklin, California . Hydraulic mining uses jets of water to break down gold-laden gravel banks and to wash the material through gold-separating devices (sluices and under-currents). It was one of the dominant forms of the California gold mining industry from the mid-1850s until 1884, when it was halted by federal injunction.
