Dreging in Sacramento county started before the 1880's in the American River around 65th Street. By mid-1880's dredging in the city had died out and started moving east... moved up toward Sunrise Boulevard. Both sides of the river were the same height before dredging; however, now there is an obvious difference in height between the Fair Oaks side of the river and the Rancho Cordova side of the river. Dredging went out past Highway 16... where Scott Road crosses Deer Creek - some dredging there on the American River.
The Idaho Mining Company, the company performing the dredging, offered to buy and move and rebuild Mather Air Force Base to approximately where the Sacramento municipal airport currently stands in order to dredge that land, and the offer included returning the land to Mather Air Force Base upon completion; this offer, made in 1968 was eventually given up on in 1972. A pit off of Bradshaw - gold found in the pit pays for Tiegerts gravel and sand operation.
The Idaho Mining Company took over in 1932 dredging by the river around Sunrise Boulevard to Jackson Road with five dredges - four billion dollars worth of gold was pulled out which at today's prices would be a trillion dollars, and, it is estimated that only 10% of the gold has been found. Elk Grove gold is too deep, and therefore too expensive to obtain because it is approximately 300 feet below the surface.
DIAMONDS... there are diamonds in California: the Star of California, a 42 carat diamond now in the Smithsonian Museum, the Serin Dipity, the Double Dipity and the Panther from Dunsmire, also some by Oroville, and also here as a result of the alluvial push from 24,000 years ago.
