The North Bloomfield Mining and Gravel Company, founded in 1866 in North Bloomfield, California, managed a prominent hydraulic gold mining operation at Malakoff Mine following the California Gold Rush. It stood out as the largest and most heavily funded enterprise of its era and continued functioning until 1910. Its profitability suffered after the pivotal verdict in Woodruff v. North Bloomfield Gravel Mining Company.
Situated within the boundaries of Malakoff Diggins State Historic Park, just east of California State Route 49, the company's original administrative building still exists.
History
The enterprise was owned by a group of 30 investors from San Francisco, led by railroad magnate Lester I. Robinson and silver entrepreneur William Ralston. They acquired crucial water rights across Canyon Creek’s watershed, sharing these resources with the Summit Water and Irrigation Company. Major reservoirs included Bowman Lake along with Crooked and Island Lakes. The primary water conduit, known as Bloomfield Ditch, was mainly dedicated to supplying mining operations rather than agricultural irrigation.
The company operated several sites throughout Nevada County, California, such as Union Diggings at Columbia Hill, but its principal operation was centered at Malakoff Mine. In 1874, a drainage tunnel was completed through solid rock at Malakoff, allowing the processing capacity to reach up to 50,000 tons of gravel daily, utilizing seven hydraulic monitors running continuously. A report from the end of 1879 noted a technological advancement: the implementation of electric lighting producing 12,000 candlepower, which replaced traditional pitch bonfires and improved night-time mining efficiency.
Sawyer Decision
The disposal of tailings into the Yuba River caused extensive damage to farmland extending as far west as Sacramento, igniting one of California's earliest significant environmental disputes. In September 1882, Edwards Woodruff, a New York native and local landowner near Marysville, filed an anti-debris lawsuit titled Woodruff v. North Bloomfield Gravel Mining Company. The trial commenced by June 1883. On January 7, 1884, Judge Lorenzo Sawyer delivered a landmark ruling—known as the Sawyer Decision—that became one of the first environmental judgments in United States history. Although North Bloomfield Mining and Gravel Company operated the globe’s largest hydraulic gold mine in 1884, this ruling effectively terminated hydraulic mining across Gold Country. The residual tailings are still evident today in the Yuba Goldfields.

California Historical Landmark
The North Bloomfield Mining and Gravel Company received recognition as California Historical Landmark No. 852 on January 20, 1972. A commemorative plaque located at the park diggins overlook emphasizes its importance as a prominent hydraulic gold-mining enterprise, featuring an extensive canal network and a remarkable 7,800-foot drainage tunnel regarded as an engineering marvel. The marker also highlights the company's involvement as the main defendant in the pivotal anti-debris lawsuit resolved by Judge Lorenzo Sawyer’s ruling, which effectively terminated hydraulic mining practices in California. This plaque was installed by the State Department of Parks and Recreation in collaboration with local organizations on June 11, 1972.
