  1. Snow and water supply data

    Yukon snow survey bulletins and water supply forecasts are issued every March, April and May.

    These bulletins provide:

    • a summary of winter meteorological and streamflow conditions for Yukon;
    • current snow depth and snow water equivalent observations for 58 locations; and
    • long-term averages and monthly data.

    We use this information to make total runoff volume projections for the summer and to estimate peak flow for Yukon's main river basins and sub-basins. This includes the upper and lower Yukon, Pelly, Stewart, Liard, Alsek, Porcupine and Peel rivers.
