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). The main stem Feather River begins in Lake Oroville, where its four long tributary forks join together—the South Fork, Middle Fork, North Fork, and West Branch Feather Rivers. 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 Flatrock River, also known as Flatrock Creek and other variants of the two names, is a 98-mile-long (158 km) tributary of the East Fork of the White River in east-central Indiana in the United States. Via the White, Wabash and Ohio rivers, it is part of the watershed of the Mississippi River, draining an area of 532 square miles (1,380 km2).
Larrys Creek is a 22.9-mile-long (36.9 km) tributary of the West Branch Susquehanna River in Lycoming County in the U.S. state of Pennsylvania. A part of the Chesapeake Bay drainage basin, its watershed drains 89.1 square miles (231 km2) in six townships and a borough. The creek flows south from the dissected Allegheny Plateau to the Ridge-and-valley Appalachians through sandstone, limestone, and shale from the Devonian, Mississippian, and Pennsylvanian periods.
Dry Creek is a 43.0-mile-long (69.2 km) stream in the California counties of Sonoma and Mendocino. It is a tributary of the Russian River, with headwaters in Mendocino County.
Sonoma Creek is a 33.4-mile-long (53.8 km) stream in northern California. It is one of two principal drainages of southern Sonoma County, California, with headwaters rising in the rugged hills of Sugarloaf Ridge State Park and discharging to San Pablo Bay, the northern arm of San Francisco Bay. The watershed drained by Sonoma Creek is roughly equivalent to the wine region of Sonoma Valley, an area of about 170 square miles (440 km2). The State of California has designated the Sonoma Creek watershed as a “Critical Coastal Water Resource”. To the east of this generally rectangular watershed is the Napa River watershed, and to the west are the Petaluma River and Tolay Creek watersheds.
Muddy Creek is a tributary of the Susquehanna River in York County, Pennsylvania, in the United States.
Austin Creek is a 16.0-mile-long (25.7 km) southward-flowing stream in the mountains of western Sonoma County, California which empties into the Russian River about 4 miles (6 km) from the Pacific Ocean.
Maacama Creek is a 7.3-mile-long (11.7 km) stream in northern Sonoma County, California, U.S.A., which empties into the Russian River near the city of Healdsburg.
Atascadero Creek is an 8.8-mile-long (14.2 km) north-flowing stream in Sonoma County, California, United States, which empties into Green Valley Creek.
Big Sulphur Creek is a westward-flowing stream in northern Sonoma County, California, United States, which springs from The Geysers in the Mayacamas Mountains and runs 20 miles (32 km) to empty into the Russian River.
Dutch Bill Creek is a 6.5-mile-long (10.5 km) north-flowing stream in the hills of western Sonoma County, California, which empties into the Russian River at Monte Rio about 7 miles (11 km) from the Pacific Ocean.
Bear Creek is a 2.8-mile-long (4.5 km) stream in eastern Sonoma County, California, United States, a tributary of Sonoma Creek.
The Miller River is a river in King County, Washington. Named for 1890s prospector John Miller, it is a tributary of the Skykomish River, which it joins near the community of Miller River. The Miller River is about 3.5 miles (5.6 km) long from the confluence of its main tributaries, the East Fork and West Fork. Miller River Campground is located just downriver from the confluence.
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 Eel River is the smallest of four major tributaries of the Eel River in northwestern California in the United States. It drains a rugged wilderness area of about 286 square miles (740 km2) in the California Coast Ranges, and flows through national forests for much of its length. Very few people inhabit the relatively pristine watershed of the river; there are no operational stream gauges and only one bridge that crosses the river, near the boundary between Trinity and Mendocino Counties.
The Jemez River is a tributary of the Rio Grande in the U.S. state of New Mexico. The river is formed by the confluence of the East Fork Jemez River and San Antonio Creek, which drain a number of tributaries in the area of the Jemez Mountains and Santa Fe National Forest. The Jemez River is about 50 miles (80 km) long, or about 80 miles (130 km) long if its longest headwater tributary, San Antonio Creek, is included. The East Fork Jemez River is about 22 miles (35 km) long. Both San Antonio Creek and the East Fork Jemez River flow through intricate meanders along their courses. The East Fork Jemez is a National Wild and Scenic River.
The Rice Fork is a 22.7-mile-long (36.5 km) tributary of the Eel River in Lake County, California. The Rice Fork begins on the upper northwest side of Goat Mountain, on the Colusa-Lake County line, at an elevation of over 6,000 feet (1,800 m). It quickly descends the steep western slope of the mountain, then bends northward, and flows northwesterly down a narrow winding steep walled canyon for about 18 miles (29 km), crossing two forest roads and adding many tributaries, ending its journey at the southern tip of Lake Pillsbury, at a varied elevation around 1,800 feet (550 m), depending on the lake level. Before the construction of Scott Dam in the 1920s, which formed Lake Pillsbury, the Rice Fork ran directly into the Eel River. It is one of Lake County's longest streams.
Elder Creek is a major stream in Tehama County, California and a tributary of the Sacramento River. It originates at the confluence of its North, Middle and South Forks, which begin in the Mendocino National Forest, and flows 27 miles (43 km) east to its confluence with the Sacramento River about a mile east of Gerber and 2 miles (3.2 km) north of Tehama. Measured to the head of its longest tributary, the South Fork, Elder Creek has a total length of 42 miles (68 km), draining a watershed of about 150 square miles (390 km2). Like the other streams draining this part of the western Sacramento Valley, Elder Creek is a highly seasonal stream that flows only during the winter and spring.
