Query Notes and Methods
Critical temperature thresholds for adult salmonids in the Columbia River
Compiled by: W. Nicholas Beer, 2016

Apart from the impact of high temperatures that may lead to metabolic stress (Brett 1995) or disease (McCullough 1999), temperatures have an impact on travel rates (Bjornn and Reiser 1991). There are two components to this. First, bioenergetic efficiency allows fish to swim most rapidly in optimal temperature waters (Hinch and Rand 2000). E. g., Columbia River Chinook and Fraser River sockeye swim most rapidly near 16°C (Lee et al. 2003; Salinger and Anderson 2006). Second, sufficiently high temperatures delay migration, e.g. Chinook are known to slow their migration above 20°C (Goniea et al. 2006), and several species completely cease migration above 21°C including Chinook, steelhead and sockeye (McCullough 1999; Quinn et al. 1997) .

Although individual tolerances to temperature are determined partly on acclimation temperatures, diel variation, spatial variability and fish size, temperatures above 21°C are widely regarded as detrimental to migration. The U.S. Environmental Protection Agency recommends using a metric called the “7 day average of daily maximums” (a.k.a 7DADM) which “can be used to protect against acute effects, such as lethality and migration blockage conditions” (EPA 2003). This is 20°C for salmon/trout migration.

Finally, extreme temperatures lead directly to mortality. These thresholds are near 24°C and 25°C for steelhead and Chinook respectively.
