Predicting stream temperatures under a climate change scenario : impacts on critical temperatures for Atlantic salmon (Salmo salar) / by Nathalie N. Brodeur ... [et al.]. : Fs97-6/3118E-PDF

Over the next century, the mean annual air and water temperatures of the Little Southwest Miramichi River are projected to increase by 4.4°C and 3.2°C, respectively. The predicted increase in water temperature will ultimately impact the number of days exceeding critical water temperature thresholds for Atlantic salmon. Under these changes, days surpassing the critical thresholds (Tw-min > 20°C and Twmax > 23°C) could increase by 21 to 41 days per year. Results from this study support many others that have predicted increasing stream temperature trends over the next century. As such, the management of cold water habitats and angling activities will become increasingly more important in the future for the protection Atlantic salmon populations.
