Salmon and trout respond to river temperature fluctuations by moving into cooler areas when main-stem temperatures exceed their upper tolerance limits. In a climate warming context, these areas are increasingly recognized as an important aspect of stream habitat especially for cold water fish such as salmonids, because they can act as thermal refuges during summer months. This thesis aims firstly to examine the physical processes that underlie the formation of various types of cold water anomalies in a river setting, and secondly, to determine which anomaly types are being used as refuges by salmonids in hot weather. Two main refuge forming processes are investigated, this in two Quebec salmon rivers. These are 1) thermal plume formation fr...
