Figure 2. (a) Mean monthly precipitation, with ranges measured over the study period. (b) Mean daily air temperature at the area-weighted mean catchment elevation (1,783 m a.s.l.), with the seven-day moving mean (black). (c) Mean monthly inflows, with ranges measured over the study period. (d) Normalized cumulative inflows for water years in the study period (2006–2007 to 2017–2018), with the mean (black). Identified hydrological seasons based on streamflow are moderate flow winter season (1), high-flow snowmelt season (2), drying season (3), and low-flow season (4)
