Cottonwood Creek is known for the runs of what genus of Pacific salmon?
Cottonwood Creek (Sacramento River) Cottonwood Creek is a major stream in Northern California in the United States and is a tributary of the Sacramento River. About 68 mi long measured to its uppermost tributaries, the creek drains a large rural area bounded by the crest of the Coast Ranges, traversing the northwestern Sacramento Valley before emptying into the Sacramento River near the town of Cottonwood. For its entire length, it defines the boundary of Shasta County and Tehama County. Because Cottonwood Creek is the largest undammed tributary of the Sacramento River, it is known for its Chinook salmon and steelhead runs.
Oncorhynchus kawamurae Oncorhynchus kawamurae, the "black kokanee", or "kunimasu" (国鱒 or クニマス ) in Japanese, is a Japanese species of salmon which was thought to had gone extinct in 1940, but was discovered to still have a living population in 2010.
