Map of the Columbia River and its Tributaries
The map above is taken from a report from the Army Corps of Engineers, which was written for the second session of the 81st Congress. The map shows the Columbia River and its tributaries largely north of the Canadian-American border. The river originates in Columbia Lake in British Columbia before winding south through Washington, forming the Washington-Oregon border, and meets the Pacific Ocean to the west.
