 note = {In this research, the impact of global climate change and human activities on Ogii Lake Basin were studied using RS, and GIS. Ogii Lake and Khugshun Orkhon River’s water was classified as clean and slightly polluted water. The most accurate water index for delineating the surface area of Ogii Lake was MNDWI-1(R=0.94, p < 0.01). Evaporation from the lake was estimated using the energy-budget method based on historical reanalysis (ERA5) daily data. Total annual evaporation from Ogii Lake increased steadily over the last three decades; comparing to 1989, annual evaporation increased by 20.02, 25.79, and 32.4 mm in 1999, 2009, and 2019, respectively. Comparison result showed that precipitation is not a main part of the water source for Ogii Lake. The result of the estimated water balance between 2016 and 2019 was demonstrated that both surface and groundwater have a considerable influence on Ogii Lake’s water balance. The GWPZs of Ogii Lake Basin was delineated integrating the AHP and MCDM methods. The highest GWPZs was coincided with deepest part of the lake, where the tectonic fault cross Ogii Lake.},
