The authors examine the characteristics of the ice and thermal regime of the Gunt River in connection with the planning of a cascade of hydrostations on the river. The thermal regime of a mountain river is determined by the amount of heat contained in the water mass and its change along the length of the river as a consequence of heat exchange of the water surface with the atmosphere. On the basis of the characteristics of the winter thermal regime, the authors schematically divide the investigated river into six stretches. They determine by this analysis that under conditions of a winter of normal severity, the stretch of the site of the Pamir No. 1 hydrostation is in a zone of increased probability of icing, and so in the design it is necessary to use structural and regime measures to prevent icing of the stationary parts of gates and to heat the trash racks. Further, to prevent the flow of shuga to the water intake, it is advisable to construct a shuga-retaining boom.
