The Lewis River is a river located in the state of Washington, flowing through the Cascade Range. It originates from the slopes of Mount St. Helens and travels approximately 50 miles before joining the Columbia River. The river is known for its scenic beauty and recreational opportunities, including fishing, kayaking, and hiking along its banks. The Lewis River is also significant for its hydroelectric power generation, with several dams built along its course.
