Colusa County, Administrative division in northern California, US
Colusa County encompasses 1,156 square miles of land in the Sacramento Valley, with the Sacramento River forming its eastern boundary.
The county became one of California's original 27 counties in 1850, receiving its name from the Rancho Colus Mexican land grant given to John Bidwell.
The Patwin band of the Wintun people first inhabited this territory, speaking two dialects of the Southern Wintuan language along the Sacramento River.
The Colusa County Transit system connects major cities within the region, while Interstate 5 and State Routes 16, 20, and 45 serve as primary transportation corridors.
The county produces substantial quantities of rice, utilizing irrigation systems that transform dry valley land into productive agricultural fields.
