West Sacramento River Walk

Hydraulic gold mining was introduced in the 1850's. Men with hoses blasted hillsides with powerful jets of water, which reduced the hills to mounds of gravel 20 times faster than with pick and shovel. Massive quantities of gravel and silt from hydraulic mining washed into the river channel, filling the streambed and contributing to flooding in the valley.

The U.S. Bureau of Mines, estimated that $81 million in gold was removed from California mines in 1852. Between 1848 and 1855, approximately $400 million worth was chipped or blasted out of the mountains. Today, that gold would be worth approximately $8.5 billion.
