Abstract: Water temperature in the northern part of the United States is significantly affected by the freezing phenomenon. Because of the freezing constraint on the variability of water temperature, there is a good correlation between the mean value and the fluctuating component. The probability density curve of water temperature variation develops a sharp peak near the freezing point. A stochastic model using two independent variables, air temperature variation and the mean daily water temperature, is developed. It is also shown that the water temperature variability tends to decrease as a dimensionless reservoir storage capacity decreases.
