The Feather River is the principal tributary of the Sacramento River, in the Sacramento Valley of Northern California. The river's main stem is about 73 miles (117 km) long. Its length to its most distant headwater tributary is just over 210 miles (340 km).

These and other tributaries drain part of the northern Sierra Nevada, and the extreme southern Cascades, as well as a small portion of the Sacramento Valley. The total drainage basin is about 6,200 square miles (16,000 km2), with approximately 3,604 square miles (9,330 km2) above Lake Oroville.

The Stehekin River is a river located in Washington state in the Pacific Northwest of the United States. It is the main river flowing into Lake Chelan. Miners arrived in Stehekin River Valley in the late 19th century. They were followed by homesteaders in the early 20th century. Today, the Stehekin River Valley is still a remote area that can only be reached by way of a 55-mile boat ride up Lake Chelan.
The Cispus River is about 54 miles (87 km) long and flows into the Cowlitz River at Lake Scanewa in the Cascade Range of Washington. Its tributaries drain most of south-central and southeastern Lewis County, extreme northeast Skamania County, and some of western Yakima County.
The Quinault River is a 69-mile (111 km) long river located on the Olympic Peninsula in the U.S. state of Washington. It originates deep in the Olympic Mountains in the Olympic National Park. It flows southwest through the "Enchanted Valley" to opposite Quinault Canyon. Several miles above Lake Quinault the river is joined by its main tributary, the North Fork Quinault River. The main stem Quinault River above this confluence is sometimes called the East Fork Quinault River. Below the confluence the river marks the boundary of Olympic National Park for several miles before emptying into Lake Quinault. After the lake, the Quinault River flows southwest, reaching the Pacific at Taholah. From Lake Quinault to the ocean, the river is contained within the Quinault Indian Reservation.

The Satsop River is a stream in the U.S. state of Washington. It has three main tributary forks, the East Fork, West Fork, and Middle Fork Satsop Rivers. The main stem Satsop River is formed by the confluence of the West and East Forks. The Middle Fork is a tributary of the East Fork. The three forks are much longer than the main stem Satsop itself, which flows south from the confluence only a few miles to join the Chehalis River near Satsop, Washington. Other significant tributaries include the Canyon River and Little River, both tributaries of the West Fork Satsop, and Decker Creek, a tributary of the East Fork Satsop River. The Satsop River's major tributaries originate in the Olympic Mountains and its southern foothills, the Satsop Hills, within Grays Harbor and Mason counties. Most of the Satsop River's watershed consists of heavily wooded hill lands. The upper tributaries extend into Olympic National Forest, approaching but not quite reaching Olympic National Park.
The North Fork Clearwater River is a major tributary of the Clearwater River in the U.S. state of Idaho. From its headwaters in the Bitterroot Mountains of eastern Idaho, it flows 135 miles (217 km) westward and is dammed by the Dworshak Dam just above its mouth in north-central Idaho. Draining a rugged watershed of 2,462 square miles (6,380 km2), the river has an average flow of over 5,600 cubic feet per second (160 m3/s), accounting for a third of the discharge from the Clearwater basin. The river drains parts of Clearwater, Shoshone, Latah, and Idaho counties. Most of the watershed is managed by the U.S. Forest Service. Some of the fish of the river include westslope cutthroat trout, rainbow trout, mountain whitefish, and the threatened bull trout. It also has smallmouth bass and a kokanee salmon run, both from Dworshak Reservoir. The North Fork drainage is home to grizzly bears, cougars, deer, moose, black bear, elk, grey wolves, and osprey. The river used to have a large steelhead run before the implementation of Dworshak Dam. The North Fork of the Clearwater is located within the Clearwater National Forest
The Laurel Fork is a 15.7-mile-long (25.3 km) stream in Virginia and West Virginia, United States.

Laurel Fork is a tributary to the North Fork South Branch Potomac River, making it a part of the Potomac River watershed. The area surrounding Laurel Fork is home to several plant and animal species found nowhere else in Virginia, and is a prime example of a northern boreal forest in the state.
