This study investigates the relationship between SLD2 water levels and fluctuations in glacial surface elevation (up to 3.6 m) and delineates subglacial lakes within the study area. We provide a comprehensive analysis based on integrated data from IPR (2018), Sentinel-1 double-differential interferogram synthetic aperture radar (DDInSAR) (2017-2022), ICESat-2 laser altimeter (2019-2022), and KOMPSAT-5 synthetic aperture radar (2021 and 2023). The concave bedrock structure and low hydraulic head areas concentrate subglacial meltwater, facilitating water accumulation and retention, forming a lake. The SLD2 lake complex is identified based on bed topography, hydraulic gradient, and relative bed reflection intensity. Its area is approximately 1/9.2 of the lake area estimated through remote sensing. Our analysis suggests that variations in water supply and discharge along the subglacial channel network influence lake water levels, as evidenced by a surface elevation increase of up to 3.69 m in the SLD2 area from 2019 to 2022. Additionally, the presence of crevasses and incoherence in the DDInSAR imagery suggests that these subglacial lakes impact glacier flow velocity.
