Watershed comparison

Click a polygon on the map to compare monthly and annual snow depth across stations.

Select a basin or sub-basin on the map to start the comparison.

Methodological note

Monthly median: a month is retained only if at least 70% of daily values are available.

Annual median (May-Oct): a year is retained only if every month from May to October satisfies the monthly coverage rule. The annual value is the median of all daily snow depth measurements within that May-October period.
