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.
It rises at the confluence of Rice Creek and a smaller unnamed stream in the southern part of the Lassen Volcanic National Park. The river flows east, receiving Warner Creek from the left, and passes the town of Chester. It then empties into Lake Almanor, which is formed by the Canyon Dam. After leaving the dam the river cuts south into a gorge, and turns southwest to receive Butt Creek from the right. The East Branch North Fork Feather River, the North Fork's largest tributary, comes in next to Caribou Rd (40°00'49.9"N 121°13'32.4"W). It then flows southwards, through several hydroelectric dams, into the north arm of Lake Oroville.
The fork's portion of the Feather River Canyon is notable as part of the Feather River Route, and the railroad's North Fork Bridge near the river's mouth is the longest reinforced concrete bridge in the US.[3]
The North Fork is heavily developed for hydroelectricity generation and is impounded by five dams, as part of three hydroelectric projects – the Upper North Fork Feather River Project, the Rock Creek-Cresta Hydroelectric Project and the Poe Hydroelectric Project. The system is so extensive that it has been dubbed the "Stairway of Power".[4][5]
The Feather River Canyon is well known for high winds. The "Jarbo Winds", named for nearby Jarbo Gap, often blow down the canyon from the northeast. These katabatic winds are caused by high-pressure air over the Great Basin seeking a path through the Sierra Nevada to the low-pressure voids on the California coast. The 2018 Camp Fire, the deadliest wildfire in California's history, was driven into Paradise by these winds.[6] Meteorological records show 36 days since 2003 with gusts of 100 mph or more, up to 200 mph.
