History of the River
The Pend Oreille River ( pond-ə-RAY) is a tributary of the Columbia River, approximately 130 miles (209 km) long, in northern Idaho and northeastern Washington in the United States, as well as southeastern British Columbia in Canada. In its passage through British Columbia its name is spelled Pend-d'Oreille River. It drains a scenic area of the Rocky Mountains along the U.S.-Canada border on the east side of the Columbia. The river is sometimes defined as the lower part of the Clark Fork, which rises in western Montana. The river drains an area of 66,800 square kilometres (25,792 sq mi), mostly through the Clark Fork and its tributaries in western Montana and including a portion of the Flathead River in southeastern British Columbia. The full drainage basin of the river and its tributaries accounts for 43% of the entire Columbia River Basin above the confluence with the Columbia. The total area of the Pend Oreille basin is just under 10% of the entire 258,000-square-mile (670,000 km2) Columbia Basin. Box Canyon Dam is currently underway on a multimillion-dollar project for a fish ladder.
