Analysis of the streamflow characteristics of fourteen streams and rivers on the catchment area of the Kolyma reservoir showed that spatial variations of the annual total streamflow agree with the variability of precipitation. The maximum daily flow and duration of the flow period depend on the catchment area. The fraction of different landscapes of the watershed is indicator of such processes as the water discharge from the talik aquifers at the river valleys and the cryogenic redistribution of streamflow that affect the variation coefficient of streamflow, the maximum flow and the duration of the flow period.
