Starting in the 1920s, water was brought to the area through the 90-mile Davidson Ditch for gold mining. The Goldstream Dredge No. 8 cut a 4.5-mile track and produced 7.5 million ounces of gold.
The dredge was named a Historic Mechanical Engineering Landmark by the American Society of Mechanical Engineers in 1986. In 1984, it was listed as a historic district on the National Register of Historic Places.
Today, it is open to the public. During summer months, tours of the dredge and gold panning are available for a small fee.
