The Tolt River is located in the western foothills of the Cascade Mountains in north central King County in the U.S. state of Washington. The river begins at the confluence of the North Fork Tolt and South Fork Tolt rivers. It flows southwest joining the Snoqualmie River near Carnation, Washington. The Tolt River watershed is part of the larger Snohomish River and Puget Sound drainage basin.


The South Fork Tolt watershed provides ~30% of the drinking water for Seattle area residents.

Name origin

The name Tolt comes from the Lushootseed village name tultxʷ or tulq. [3]

Snoqualmie River

The Snoqualmie River is a 45-mile (72 km) long river in King County and Snohomish County in the U.S. state of Washington. The river's three main tributaries are the North, Middle, and South Forks, which drain the west side of the Cascade Mountains near the town of North Bend and join near the town of Snoqualmie just above the Snoqualmie Falls. After the falls the river flows north through rich farmland and the towns of Fall City, Carnation, and Duvall before meeting the Skykomish River to form the Snohomish River near Monroe. The Snohomish River empties into Puget Sound at Everett. Other tributaries of the Snoqualmie River include the Taylor River and the Pratt River, both of which enter the Middle Fork, the Tolt River, which joins at Carnation, and the Raging River at Fall City.

Clark Fork River River in the U.S. states of Montana and Idaho

The Clark Fork, or the Clark Fork of the Columbia River, is a river in the U.S. states of Montana and Idaho, approximately 310 miles (500 km) long. The largest river by volume in Montana, it drains an extensive region of the Rocky Mountains in western Montana and northern Idaho in the watershed of the Columbia River. The river flows northwest through a long valley at the base of the Cabinet Mountains and empties into Lake Pend Oreille in the Idaho Panhandle. The Pend Oreille River in Idaho, Washington, and British Columbia, Canada which drains the lake to the Columbia in Washington, is sometimes included as part of the Clark Fork, giving it a total length of 479 miles (771 km), with a drainage area of 25,820 square miles (66,900 km2). In its upper 20 miles (32 km) in Montana near Butte, it is known as Silver Bow Creek. Interstate 90 follows much of the upper course of the river from Butte to Saint Regis. The highest point within the river's watershed is Mount Evans at 10,641 feet (3,243 m) in Deer Lodge County, Montana along the Continental Divide.

Pend Oreille River

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. Box Canyon Dam is currently underway on a multimillion-dollar project for a fish ladder.

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.

Sultan River River draining the western side of the Cascade Range in Washington state, flowing into the Skykomish River

The Sultan River is a river in Snohomish County in the U.S. state of Washington. It is a tributary of the Skykomish River, which it joins at the town of Sultan, Washington. The river is dammed in its upper third by Culmback Dam to form Spada Lake.

Culmback Dam Dam in Snohomish County, Washington

The Culmback Dam is a large rockfill hydroelectric and water supply dam on the Sultan River, a tributary of the Skykomish River, in Washington. Built in 1965, the dam is 640 feet (200 m) long at the crest and 262 feet (80 m) high. Its reservoir, Spada Lake, provides water for 70 to 75 percent of Snohomish County and feeds the Jackson Hydro Project, providing 112 megawatts of clean energy to Snohomish county. Some critics charge that the dam has strongly impacted the runs of salmon and other migratory fish in the Sultan River by depleting gravel and sediment needed to line the riverbed. The dam's operator counters that Culmback Dam dramatically reduces flooding events, benefiting fish populations and the surrounding communities. The dam was named in honor of George Culmback, a former mayor of Everett.

Hoquiam River

The Hoquiam River is a stream in the U.S. state of Washington. It has three main tributaries, the East Fork, West Fork, and Middle Fork Hoquiam Rivers. The main stem Hoquiam River is formed by the confluence of the West and East Forks. The Middle Fork is a tributary of the West Fork.

Tye River (Washington)

The Tye River is a river in the U.S. state of Washington. It rises near Stevens Pass in the Cascade Mountains and flows west, joining the Foss River to form the South Fork Skykomish River. Its waters eventually empty into Puget Sound near Everett via the Skykomish River and Snohomish River. U.S. Route 2 follows the river's entire length. A BNSF Railway line follows most of the river except near the pass where the tracks use the Cascade Tunnel. Powerlines run by the Bonneville Power Administration (BPA) follow the Tye River west of Tunnel Creek.

Beckler River river in the United States of America
