Sheet 1: Discharge measurements at the San Pedro gauging station (1360 m.a.s.l.), along the Kosñipata River, in the Andes of Peru. The Kosñipata River at the San Pedro gauging station drains an area of 164.4 km2. Field measurements consisted of river height, flow velocity, and cross-sectional area, which together allowed us to estimate discharge and runoff over the study period. River stage height was measured from January 2010 to February 2011 using a river logger (GlobalWater WL16 Data Logger, range 0–9 m), recording river level every 15 min. The instantaneous discharge associated with each height measurement was calculated based on calibrated stage–discharge relationships. The Kosñipata River discharge at San Pedro was measured through a complete water year, with a 31-day gap partly in July and August (during low flow) that was covered by three manual measurements and the gap was filled using linear interpolation.

Sheet 2: Weekly to monthly discharge measurements at the Wayqecha gauging station (2250 m.a.s.l), along the Kosñipata River, in the Andes of Peru. The Wayqecha sub-catchment a nested catchment upstream of the San Pedro gauging station. It encompasses the headwaters of the Kosñipata River, draining an area of 48.5 km2 (See the supplementary information in Clark et al. 2014). Locations of the San Pedro and Wayqecha gauging stations are provided as GIS coverages in a companion dataset.
