Overview
Columbia County lies in northwestern Oregon along the lower reaches of the Columbia River. It is a largely rural county with several small cities and towns clustered near river valleys and transportation corridors. According to the 2010 census the county had a population of 49,351; local population patterns combine longtime rural residents with people who commute to jobs in the Portland metropolitan area.
Geography and environment
The Columbia River forms much of the county's border and has shaped its economy and landscape. Interior areas include forested hills, low river terraces and agricultural valleys. The county's natural assets include riverfront access, wetlands and working forests that support wildlife and recreation.
History and development
Settlement intensified in the 19th century as river transport and timber resources drew settlers and industry. The county was named for the great river: the Columbia River. St. Helens was established early as a river port and remains the county seat, administered from St. Helens today.
