More about North Bloomfield Mining and Gravel Company

The North Bloomfield Mining and Gravel Company of North Bloomfield, California, was established in 1866 and operated a hydraulic gold-mining operation at the Malakoff Mine subsequent to the California Gold Rush. In its day, no other company's operations matched North Bloomfield Mining and Gravel Company in size or expense.The mine is located within Malakoff Diggins State Historic Park, 16mi east of Highway 49 on Tyler Foote's Crossing Road, and 28mi north of Nevada City, California. The company office is still standing.HistoryThe North Bloomfield Mining and Gravel Company was owned by 30 capitalists from San Francisco, led by railroad baron Lester I. Robinson, and William Ralston, a silver miner from Sun Mountain in Nevada. The company's water rights were the same watershed as Summit Water and Irrigation Company's but lower down on Canyon Creek. The principal reservoir was at Bowman Lake, while others included Crooked, Island, Middle, Round, English/Rudyard, Sawmill, and Shotgun Reservoirs. The company's main canal was the Bloomfield Ditch, but, according to Superintendent L.L. Meyers, only a small fraction of the ditch's water was used for irrigation and most was used for mine operations.The company had numerous operations in Nevada County, including Union Diggings at Columbia Hill, but those at Malakoff Mine were the most notable. Completed in 1874-11-15, the North Bloomfield Mining and Gravel Company carved a 7800ft long drainage tunnel through solid bedrock at Malakoff Mine. After tunnel completion, the company reached its peak processing of 50,0000 tons of gravel each day by operating seven giant monitors twenty-four hours a day, seven days a week. In the company's 1879 year-end report, the company's president hailed a major improvement:
