From 1957 to 1980, Dick and Anna Singer mined, recorded earlier efforts, made studies, and sold their findings to Gold Fields Mining ...
In 1893, the California Debris Commission began to dredge the Yuba River near Marysville to mitigate the environmental damage from hydraulic mining, and piled the gravel along the river's banks.
