Sicard Flat is named for Theodore Sicard, who settled here in 1848 and mined for gold in the ravine. At that time, the Yuba River ran directly past Sicard Flat, and had a bar on its north bank called Sicard Bar, just upstream from Parks Bar. Theodore Sicard ran a store at Sicard Bar. Sicard Bar no longer exists, because extensive hydraulic mining at Sicard Flat washed away about 50 acres of ground, including Sicard Bar.1

The History of Yuba County, California (Chapter XXIX: Parks Bar Township) by Thompson & West, 1879, described Sicard Flat this way:

This is a flat just back of Parks Bar and Sicard Bar. It derived its name also from Theodore Sicard, who opened the mines. Work was commenced here in 1850, in the ravine, where rich surface diggings were found. When the gravel mines were discovered Sicard Flat became a great hydraulic mining point, and is being worked by that process at the present time. It had a few stores, etc., and John Rose had a corral here where he slaughtered cattle to supply his markets in the mines. About fifty acres of ground have been washed away. The South Feather River Mining Company have been working this place since 1871. They have about fifty miles of ditch running to the flat from Feather river, two miles of flume, three thousand feet of pipe, and keep two nozzles working night and day. The town now has eight dwellings and one blacksmith shop, but no store. The population is about fifty.
