Hammonton (formerly, Dredgertown and Dredgerville) is a former settlement in Yuba County, California. It is located 3.5 miles (5.6 km) south of Browns Valley, at an elevation of 131 feet (40 m). Hammonton was a company town for the Yuba Consolidated Mines, which dredged gold from the Yuba River floodplain. Established in 1906, Hammonton had 250 residents, a store, service station, and swimming pool by 1938, when the townspeople were forced to move two miles so that the original townsite could be razed and dredged. In 1957, the residents were again relocated, this time to Linda, so that the new townsite could also be dredged; Hammonton ceased to exist at that time. The Yuba Goldfields now cover the townsites. A post office operated at Hammonton from 1906 to 1957. The name is in honor of W.P. Hammon, gold-dredging company official.

Located along the Yuba River approximately 6–12 miles (10–20 km) upstream of the town of Marysville, in Yuba County, the Hammonton dredge field was actively dredged for gold from 1904 to 1968. In total, more than one billion cubic yards (760×10^6 m3) of river sediment and lesser hydraulic mining debris was dredged to produce an estimated 5.14 million ounces (146×10^6 g) of gold. The goldfields are noted for their otherworldly appearance (a result of gold dredging operations), filled with roughly linear mounds of gravels (called dredge tailing windrows), ravines, streams and turquoise-colored pools of water. From the air, the goldfields are said to resemble intestines. Wild turkeys, deer, ducks, Beavers, herons, bald eagles, Northern river otters and even mountain lions now live in the goldfields.
