COLUSA. County seat, Colusa. Created February 18, 1850. Named after two Mexican land grants; Coluses (1844) and Colus (1845). The name of the county in the original state legislative act was spelled Colusi, and often in newspapers was spelled Coluse. The word is derived from the name of an Indian tribe living on the west side of the Sacramento River.
