  "abstract": "Study region: Liujiaxia Reservoir, a large and highly regulated reservoir in the upper Yellow River Basin, northwestern China. Study focus: Stable water isotopes in precipitation and reservoir surface water were monitored from August 2021 to July 2023. Local evaporation lines (LELs) were used to characterize evaporative enrichment, and the Craig-Gordon isotope mass-balance framework implemented in Hydrocalculator was used to quantify evaporation over inflow ratios (E/I) and their seasonal variability. New hydrological insights for the region: Reservoir water became progressively enriched in δ¹⁸O and δ²H from the inlet toward the outlet and open water sections, indicating cumulative evaporative fractionation. The LEL slope decreased from 8.79 in winter to 3.46 in summer, while isotope derived E/I ranged from 0.41% to 7.82%, with the largest relative evaporation losses occurring in summer. Variability in inlet and outlet water isotopic composition dominated the propagated uncertainty in E/I, emphasizing the importance of representative isotope sampling for constraining evaporation estimates. Stable isotope mass balance therefore provides a useful means of identifying periods of relatively high evaporation loss in large regulated reservoirs and can complement conventional water balance monitoring, although E/I should be interpreted as a relative evaporation loss indicator rather than an absolute evaporation flux.",
