The total length of the Columbia River, from its source at Columbia Lake to its mouth at the Pacific Ocean, is approximately 1,243 miles (2,000 kilometers). It is one of the largest rivers in North America by volume, with an average discharge of over 25,000 cubic feet per second (708 cubic meters per second).
