The Pend Oreille River 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.
The Pend Oreille River begins at Lake Pend Oreille in Bonner County, Idaho in the Idaho Panhandle, draining the lake from its western end near Sandpoint (The Clark Fork River enters the lake from its eastern end). It flows west, receiving the Priest River from the north at the town of Priest River, then flows into southern Pend Oreille County in northeastern Washington at Newport. Once in Washington it turns north, flowing along the eastern side of the Selkirk Mountains. It flows roughly parallel to the Idaho border for approximately 50 miles (80 km), through the Colville National Forest, past Tiger and Metaline Falls. It crosses the international border into southeastern British Columbia, looping west for about 15 miles (24 km) and joining the Columbia from the east, approximately 0.2 miles (0.32 km) north of the international border and approximately 5 miles (8 km) south of Montrose.
