Biographical / Historical

Gold dredging in California began in 1850 when a small river boat was fitted out as a dredge and gravel mining was attempted above Marysville, California on the Yuba River. The first successful gold dredge in California was built in 1898 by Biggs, Butte County resident Wendell P. Hammon, the "Dredger King," and his partner, Thomas Couch, a Montana mining businessman. This first model and those that followed consisted of a floating hull, a digging ladder, an endless chain of buckets, screening apparatus, gold-saving devices, pumps, and a stacker. The California dredge was developed from models used earlier in New Zealand and in Montana, proving to be much more efficient than earlier one-bucket attempts.

Hammon was instrumental in founding the Yuba Construction Company in 1906, by purchasing the Western Engineering Company and merging it with his own steel from a casting foundry in Marysville. Four large machine shops were built near Oroville to maintain and build the dredgers. Hammon founded the Yuba Consolidated Gold Fields on the Yuba River in 1904. This company became a large, profitable placer operation, a proving ground for new dredge designs and a training ground for dredge operators and others in this global industry. As many as 50 dredgers worked in the Feather River/Yuba River drainage at one time.

The Yuba Construction Company changed its name to the Yuba Manufacturing Company and later became a subsidiary of the Yuba Consolidated Gold Fields. In 1957 these companies merged into Yuba Consolidated Industries. The Yuba Consolidated Gold Fields was later incorporated into the Western Water Company. Yuba dredges have been built and shipped from California to worldwide markets during the first half of the 20th century. These "gold boats" were shipped in pieces and assembled where the mining would take place.

Abstract

This collection includes photographs, photo albums, negatives, and blueprints pertaining to the operations of Wendall P. Hammon, Yuba Construction Company and Yuba Consolidated Gold Fields. Photographs, albums, negatives and blueprints relate to the dredging, manufacturing, and mining activities of the Hammon enterprises.

Arrangement

The collection is arranged into two series

Series 1: Photographs Series 2: Blueprints

Photographs and negatives are arranged according to dredger number, location, and operations. All negatives are nitrate based and for staff use only. Scanned copies are available.

In order to better serve the researcher, blueprints have been arranged by dredger number, blueprint manufacturers, dredger company name, or a type of dredger part. Yuba Consolidated Industries originally organized the blueprints by dredger part, such as ladders, tumblers, or buckets.

*Please note: Many of the dredgers have been rebuilt and/or relocated, so they may have more than one number or name associated with them.

Processing Information

Processing of the Yuba Consolidated Industries Records was generously funded by the Andrew W. Mellon Foundation, and administered by the Council on Library and Information Resources (CLIR). The [ABC repository] was awarded a Cataloging Hidden Special Collections and Archives grant from 2010-2012, "Uncovering California's Environmental Collections," in collaboration with eight additional special collections and archival repositories throughout the state and the California Digital Library (CDL). Grant objectives included processing of over 33 hidden collections related to the state's environment and environmental history. The collections document an array of important sub-topics such as irrigation, mining, forestry, agriculture, industry, land use, activism, and research. Together they form a multifaceted picture of the natural world and the way it was probed, altered, exploited and protected in California over the twentieth century. Finding aids are made available through the Online Archive of California (OAC).
