A situation in which a rapidly warming lake is connected with a relatively cool lake is described. Three species of fish, whitefish, lake trout, and burbot, exhibited a definite migration from the warmer to the cooler lake, the larger fish leaving first. The number of catchable lake trout present in early spring in the warmer lake was determined and the concentration was found to be of the same order as that for other Canadian lakes.
