There are more than 60 dams in the Columbia River watershed in the United States and Canada. Tributaries of the Columbia River and their dammed tributaries, as well as the main stem itself, each have their own list below. The dams are listed in the order as they are found from source to terminus.
The Snake Riverâa major tributary of the Columbia Riverâoriginates in the Teton Wilderness, flows north into Yellowstone National Park, and then turns south, passing through the John D. Rockefeller, Jr., Memorial Parkway into Grand Teton National Park. The river flows through Idaho and joins the Columbia in Washington. The Snake River is 1,040 miles long (1,674 km); 42 miles (68 km) of it are in Yellowstone National Park. The river feeds Jackson Lakeâa natural lake augmented by a dam, resulting in regulated downstream flows since 1907.
