Mining History: Hydraulic Mining
The Malakoff Diggins is the largest hydraulic mining site in California. Years of hydraulic mining has left an artificial canyon 7,000 feet long, 3,000 feet wide, and 600 feet deep. Early, small scale placer miners referred to the area as Humbug due to many failed attempts to mine the local rivers. Yet, gold was there.

Hydraulic fracturing in mining – CSIROpedia
Background. Hydraulic fracturing involves producing and extending fractures in rock by injecting a fluid under pressure into a section of a borehole. The fluid pressure produces tensile stress in the rock at the borehole wall, causing a fracture to start. The fluid then enters the fracture and opens and extends it deep into the rock.
Hydraulic Mining Historical Marker
Hydraulicking also swept large amounts of silt into the Sacramento and San Joaquin rivers, causing frequent flooding. Valley farmers organized, and an 1884 court decision made hydraulic mining operations liable for downstream damage.
