| Description |
Salmonids (salmon, trout and char – including bull trout) require cool, well-oxygenated water to survive. The maximum temperature that salmonids can tolerate varies with species, life-stage (e.g., fry, fingerling or adult), prior acclimation, oxygen availability, duration of warmer temperature, and the presence of pollutants. Given the opportunity, juvenile and adult salmon will occupy water that is 13-18º C (55-64º F), with the warmer water selected only if excess food is available. Water temperatures of approximately 23-25º C (73-77º F) are lethal to salmon and steelhead, and genetic abnormalities or mortality of salmonid eggs can occur above 11º C (52º F). |
