Placer mining dredging still one of California's leading industries
Use of gold dredges in California; large gold production; development of design of dredge; power for dredging is usually electric, if available, and is delivered to dredge by submarine shore cable floated on barges; most dredges in California have a-c electric equipment, but in recent years several have been equipped with d-c units and variable speeds.
