the Board on Geographic Names in 1927. USGS topographic maps, as of 1995, are mislabeled for South Arm, North Arm Rice Creek, Rice Creek and North Fork Feather River. Rice Creek, labeled North Arm Rice Creek on USGS topo maps, flows south from its source at Cold Boiling Lake, , in Lassen Volcanic National Park, through Crumbaugh Lake, and south to join the South Arm Rice Creek, forming the North Fork Feather River. The North Fork's length is about , or about including Rice Creek. The total length of the Feather River from the source of Rice Creek to the Sacramento River is about . From its source in Feather River Meadows the North Fork flows east. A tributary emerges from Buzzard Springs and flows into the Stump Ranch Marsh Area, where it joins the North Fork, which then flows southeast to Lake Almanor, a reservoir created by Canyon Dam. Below Canyon Dam the North Fork flows generally southwest through the Sierra Nevada, receiving the East Branch North Fork Feather River near Belden. The North Fork continues flowing south below the East Branch confluence. Bucks Creek, which drains Bucks Lake near Bucks Lake, California, joins from east. The North Fork flows southeast into Butte County, becoming the northern arm of Lake Oroville. Before Oroville Dam was built the mouth of the North Fork was located at . After the North Fork's mouth was inundated by Lake Oroville the North Fork's mouth was changed to be at , according to the USGS. The North Fork Feather River drains — for the North Fork itself and for East Branch North Fork. The average discharge for the two streams is about for the North Fork, and for the East Branch. East Branch The East Branch is one of the major tributaries of the Feather River system. It originates at , at the confluence of Indian Creek and Spanish Creek. Indian Creek is another long and important tributary, flowing from its source at , on the south slopes of Diamond Mountain, south and west, through Indian Valley and north of American Valley. Impounded at Antelope Dam, Indian Creek then joins Spanish Creek to form the East Branch North Fork Feather River. The longest tributary of Indian Creek is Last Chance Creek, which rises in eastern Plumas County at , south of Honey Lake, and flows generally west, joining Indian Creek at the western end
