The Clearwater River is a major tributary of the Snake River, spanning approximately 74 miles in length. It begins in the Bitterroot Mountains of western Montana and flows through Idaho before joining the Snake River. The river played a significant role in the region's history, as it was used by the Nez Perce tribe for fishing and transportation. Today, the river is used for agricultural purposes, including irrigation and hydroelectric power, with several dams and reservoirs along its length. The most notable of these is the Dworshak Dam, which is the third tallest dam in the United States. The river is also a popular recreational destination, offering fishing, kayaking, and white-water rafting opportunities. The Clearwater National Forest is located along the river and provides ample opportunities for hiking, camping, and wildlife viewing.
