The Watson River drains an ice sheet area of about 12.000 km2 (Lindbäck et al., 2015) and a 590 km2 proglacial area (Hasholt et al., 2013). During the peak of the melt season, large amounts of water and sediment are transported by the river, but during the cold season the river falls dry. River stage has been monitored by pressure transducers near the bridge in Kangerlussuaq, southwest Greenland, since 2006 (Hasholt et al., 2013; Mikkelsen et al., 2016). The data are gathered after the end of each melt season, typically in early October. The stage-discharge relation by Van As et al. (2017) is used to calculate water flux from stage.
