The Columbia River watershed covers an area of approximately 668,000 square kilometers (about 258,000 square miles). It spans parts of seven U.S. states—Washington, Oregon, Idaho, Montana, Nevada, Utah, and Wyoming—along with the Canadian province of British Columbia. This extensive watershed includes numerous tributaries and plays a crucial role in the ecology and economy of the Pacific Northwest.
