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—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 Cosumnes River is a river in northern California in the United States. It rises on the western slope of the Sierra Nevada and flows approximately 52.5 miles (84.5 km) into the Central Valley, emptying into the Mokelumne River in the Sacramento-San Joaquin Delta.
Lake Oroville is a reservoir formed by the Oroville Dam impounding the Feather River, located in Butte County, northern California. The lake is situated 5 miles (8 km) northeast of the city of Oroville, within the Lake Oroville State Recreation Area, in the western foothills of the Sierra Nevada. Known as the second-largest reservoir in California, Lake Oroville is treated as a keystone facility within the California State Water Project by storing water, providing flood control, recreation, freshwater releases to assist in controlling the salinity intrusion into the Sacramento-San Joaquin Delta and protecting fish and wildlife.
The Yuba River is a tributary of the Feather River in the Sierra Nevada and eastern Sacramento Valley, in the U.S. state of California. The main stem of the river is about 40 miles (64 km) long, and its headwaters are split into three major forks. The Yuba River proper is formed at the North Yuba and Middle Yuba rivers' confluence, with the South Yuba joining a short distance downstream. Measured to the head of the North Yuba River, the Yuba River is just over 100 miles (160 km) long.
State Route 70 is a state highway in the U.S. state of California, connecting SR 99 north of Sacramento with U.S. Route 395 near Beckwourth Pass via the Feather River Canyon. Through the Feather River Canyon, from SR 149 to US 395, SR 70 is the Feather River Scenic Byway, a Forest Service Byway that parallels the ex-Western Pacific Railroad's Feather River Route.
The Kaweah River is a river draining the southern Sierra Nevada in Tulare County, California in the United States. Fed primarily by high elevation snowmelt along the Great Western Divide, the Kaweah begins as four forks in Sequoia National Park, where the watershed is noted for its alpine scenery and its dense concentrations of giant sequoias, the largest trees on Earth. It then flows in a southwest direction to Lake Kaweah – the only major reservoir on the river – and into the San Joaquin Valley, where it diverges into multiple channels across an alluvial plain around Visalia. With its Middle Fork headwaters starting at almost 13,000 feet (4,000 m) above sea level, the river has a vertical drop of nearly two and a half miles (4.0 km) on its short run to the San Joaquin Valley, making it one of the steepest river drainages in the United States. Although the main stem of the Kaweah is only 33.6 miles (54.1 km) long, its total length including headwaters and lower branches is nearly 100 miles (160 km).
The San Jacinto River is a 42-mile-long (68 km) river in Riverside County, California. The river's headwaters are in Santa Rosa and San Jacinto Mountains National Monument. The lower portion of the 765-square-mile (1,980 km2) watershed is urban and agricultural land. As a partially endorheic watershed that is contiguous with other Great Basin watersheds, the western side of the San Jacinto Basin is a portion of the Great Basin Divide.
Cherry Creek is a large, swift-flowing stream in the Sierra Nevada mountain range, and is the largest tributary of the Tuolumne River. The creek is 44.6 miles (71.8 km) long measured to its farthest headwaters; the main stem itself is 27.7 miles (44.6 km) long, draining a watershed of 234 square miles (610 km2) in the Stanislaus National Forest. Part of the drainage also extends into the northwest corner of Yosemite National Park.
The North Fork Feather River is a watercourse of the northern Sierra Nevada and southern Cascades in the U.S. state of California. It flows generally southwards from its headwaters near Lassen Peak to Lake Oroville, a reservoir formed by Oroville Dam in the foothills of the Sierra, where it runs into the Feather River. The river drains about 2,100 square miles (5,400 km2) of the western slope of the Sierras. By discharge, it is the largest tributary of the Feather.
The Middle Fork Feather River is a major river in Plumas and Butte Counties in the U.S. state of California. Nearly 100 miles (160 km) long, it drains about 1,062 square miles (2,750 km2) of the rugged northern Sierra Nevada range.
The Middle Fork Eel River is a major tributary of the Eel River of northwestern California in the United States. It drains a rugged and sparsely populated region of the Yolla Bolly Mountains, part of the California Coast Range, in Trinity and Mendocino Counties. Its watershed comprises roughly 745 square miles (1,930 km2) of land, or 20% of the entire Eel River basin. The river provides groundwater recharge and is used for recreation and for industrial, agricultural and municipal water supply by residents.
Stony Creek is a 73.5-mile (118.3 km)-long tributary of the Sacramento River in Northern California. It drains a watershed of more than 700 square miles (1,800 km2) on the west side of the Sacramento Valley in Glenn, Colusa, Lake and Tehama Counties.
Red Clover Creek is a west-northwestward-flowing stream originating on Horton Ridge east of the Sierra Nevada crest in Plumas County, California, United States. It courses 27 miles (43 km) through Dotta Canyon and Red Clover Valley to its confluence with Last Chance Creek in Genesee Valley, just above its confluence with Indian Creek, which flows into the East Branch North Fork Feather River. The Red Clover Valley sits at an elevation of about 5,400 feet (1,600 m) and is located on the east side of the Sierra Nevada crest, approximately 60 miles (97 km) north of Truckee and 30 miles (48 km) east of Quincy.
The Feather Headwaters is the watershed of the Feather River above Lake Oroville, totaling 3,450 sq mi (8,900 km2). Subdivided into 3 watersheds, the North Fork Feather Watershed is 1,090 sq mi (2,800 km2)—including the West Branch drainage of about 282.5 sq mi (732 km2), the East Branch North Fork Feather Watershed is 1,010 sq mi (2,600 km2), and the Middle Fork Feather Watershed is 1,350 sq mi (3,500 km2)—including the South Fork drainage of about 132 sq mi (340 km2). Headwaters drainage is impaired by the Palermo Canal at Oroville Dam, the Hendricks Canal at the West Branch Feather River, and the Miners Ranch Canal at the South Fork's Ponderosa Reservoir. Additionally, the Pacific Gas and Electric Company releases Upper Feather water into the Hyatt Generating-Pumping Plant for hydroelectric generation during daily peak demand.
Copper Creek is a southern tributary of the Klamath River in the U.S. state of California. Arising in the Klamath Mountains, the creek drains a narrow watershed of about 120 square miles (310 km2). Historically, Copper Creek was the site of at least one Hupa Native American village, then was extensively mined for gold in the 1850s. The origin of the name comes from the peach-colored cliffs that line the lower few miles of the canyon.
The East Fork Carson River is the largest tributary of the Carson River, flowing through California and Nevada in the western United States. The north-flowing river is 61 miles (98 km) long and drains a mostly rural, mountainous watershed of 392 square miles (1,020 km2).
Indian Creek is a major stream in the southern Cascade Range and northern Sierra Nevada of Plumas County, California and is part of the Feather River system. The creek is 47 miles (76 km) long, flowing through a series of small towns and farming valleys in a rural, mountainous area.

From there it flows west to join with Red Clover Creek, its main tributary, before emptying into Indian Creek east of Genesee. Indian Creek is a tributary of the East Branch of the North Fork Feather River.
Lights Creek is a 19-mile (31 km) long stream in Plumas County, California and is a tributary of Indian Creek, part of the Feather River watershed.
