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 Ramu languages are a family of some thirty languages of Northern Papua New Guinea. They were identified as a family by John Z'graggen in 1971 and linked with the Sepik languages by Donald Laycock two years later. Malcolm Ross (2005) classifies them as one branch of a Ramu – Lower Sepik language family. Z'graggen had included the Yuat languages, but that now seems doubtful.

The Feather Headwaters are 3 watersheds totaling 3,450 sq mi (8,900 km2) and which drain to Lake Oroville. 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.
