Cottonwood Creek is known for the runs of what genus of Pacific salmon?
Chinook salmon The Chinook salmon ("Oncorhynchus tshawytscha") is the largest species in the Pacific salmon genus "Oncorhynchus". The common name refers to the Chinookan peoples. Other vernacular names for the species include king salmon, Quinnat salmon, spring salmon, and Tyee salmon. The scientific species name is based on the Russian common name "chavycha" (чавыча).
Columnaris Columnaris (also referred to as cottonmouth) is a symptom of disease in fish which results from an infection caused by the Gram-negative, aerobic, rod-shaped bacterium "Flavobacterium columnare". It was previously known as "Bacillus columnaris, Chondrococcus columnaris, Cytophaga columnaris" and "Flexibacter columnaris". The bacteria are ubiquitous in fresh water, and cultured fish reared in ponds or raceways are the primary concern – with disease most prevalent in air temperatures above 12–14 °C. It is often mistaken for a fungal infection. The disease is highly contagious and the outcome is often fatal. It is not zoonotic.
