Snow surveys and water supply forecasts

  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 the 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 the Yukon's main river basins and sub-basins. This includes the upper and lower Yukon, Pelly, Stewart, Liard, Alsek, Porcupine and Peel rivers.

    2022 Yukon snow survey bulletin and water supply forecasts

    • May 2022
      • The May 1 survey shows snowpack continues to be record-setting in the majority of Yukon basins, due to both historically high snowfall throughout the winter and a colder than average month of April delaying the onset of snowmelt.
      • Eight of eleven monitored basins have the highest recorded May 1 basin snowpack estimate, while the remaining three basins have well above average snowpack.
      • The record-setting snowpack in many watersheds creates a high potential for spring snowmelt driven flooding in Yukon communities.

    • March 2022
