In situ observations of meltwater discharge through supraglacial stream networks are rare. In this study, we present 46 discrete discharge measurements and continuous water level measurements for 62 days (13 June to 13 August) in 2016 for a 0.6 km2 supraglacial stream catchment in southwest Greenland. The data set is divided into four files documenting 46 discrete discharge measurements (along with velocity and area) is shown in 'discharge_summary', cross-sectional profiles of discharge for every 0.2 m over the stream bed with reference to its deepest point is shown in 'discharge_profiles', time series of discharge with a 5-min temporal resolution generated using time series of water level in the stream is shown in 'discharge_timeseries', and water level measured from a cryoconite hole with a 5-min temporal resolution is shown in 'Cryoconite_hole_water_level'. A detailed uncertainty analysis was performed and documented in the publication associated with this data.
