The Willamette River is a tributary to the Columbia River, and enters the Columbia at River Mile (RM) 101. It provides the Columbia with approximately 15 percent of its annual discharge. The mouth of the Willamette lies just downstream of Hayden Island, Oregon, and provides the southern shore of Sauvie Island.
Further south the Coastal Mountain Range and Willapa Hills seem to blend into Oregon State. Directly to the east of those hills and mountains, the Puget Sound Lowlands stretch south from the Canadian border to the Columbia River. This stretch of land is home to Washington's major cities.
