Abstract Cases of water level decrease and lake shrinkage have been found in almost every freshwater ecosystem. In Indonesia, Laut Tawar Lake Upland Gayo, allegedly has experienced the surface area decrease. This study aimed to identify decrease, its driving force. We make use remote sensing data, which is processed by ArcMap Geographic Information System capture land dynamic surrounding Land cover were captured interpreting Landsat we further calibrated validated with approximately 119 ground checkpoints on lakeside. For analysis, conducted field measurements line from 41 measurement points area. To analyze rainfall temperature, Climate Hazards Group InfraRed Precipitation Station (CHIRPS) data. Our 2.4 percent or equal 1.4 km 2 35 years. Water occurs for 0.6 m 1.3 2022 2023, respectively.
