This appendix presents Figure S1 to help visualizing the isotopic signature variability in
the precipitation samples. As well as Table S1 that describes all the sub-catchments and
shows the groundwater contribution data used to make Figure 4a in the article.

Figure S1. 18O isotopic signature of the 79 precipitation samples analyzed. The lower
short-dashed line represents the snow samples weighted average. The upper shortdashed line represents the rain samples weighted average. The dashed line represents
the weighted average for all the samples.
Table S1. Landscape and soil characteristics for the different sub-catchments. ‘CSC’ is
Catchment survey code, ‘WT’ is wetlands, ‘Alluv’ is sorted glaciofluvial sediments, ‘Avg.
H’ is the average elevation of the catchment, ‘Low H’ is the lowest elevation point, and
High H is the highest point in the catchment. ‘GW’ is shortening for groundwater.
