 Spokane River watershed
|
|
The Spokane River is a tributary of the Columbia River, approximately 111 miles (179 km) long, in northern Idaho and eastern Washington in the United States. It drains a low mountainous area east of the Columbia, passing through the Spokane Valley and the city of Spokane, Washington.
The Spokane River drains the northern part of Lake Coeur d'Alene in the Idaho Panhandle, emptying into the Columbia River at Franklin D. Roosevelt Lake, approximately 180 km downstream.
From Lake Coeur d'Alene, the Spokane River traverses the Rathdrum Prairie until reaching Post Falls, Idaho where it passes over a dam, and a natural 40-foot waterfall. Continuing westward it passes over 6 more dams, three of which (Upriver Dam, Upper Falls Dam, Monroe Street Dam) are located in the city of Spokane. In Spokane, it flows over the Spokane Falls, which are located in the heart of Downtown Spokane, approximately one third of the way down the river's length. About a mile later, the river receives Latah Creek from the southeast. Soon afterwards, it is met from the northeast by the Little Spokane River, on the western edge of the city of Spokane. It flows in a zigzag course along the southern edge of the Selkirk Mountains, forming the southern boundary of the Spokane Indian Reservation, where it is impounded by the Long Lake Dam to form Long Lake, a 15 mi (24 km) reservoir. It joins Franklin D. Roosevelt Lake on the Columbia from the east at Miles. The site of historic Fort Spokane is located at the confluence of the Spokane and Columbia rivers.
