%X The global surface water range of lakes/reservoirs is a fundamental input data for many studies. Although there are currently some datasets, due to various reasons such as different data sources and dynamic changes in surface water, there are problems such as incompleteness or spatial inconsistency between datasets. Here, based on HydroLAKES, GRanD, and OpenStreetMap, a new global lake/reservoir water surface range dataset (GLRSED) has been created, which includes the spatial range and basic attributes (such as name, area, lake type, and source) of 2.17 million lakes/reservoirs. By spatially overlaying GLRSED with other auxiliary data, we identified mountainous lakes, inflow lakes, reservoirs, glacial lakes, and permafrost lakes. In addition, we also calculated the surface water and ocean topography (SWOT) trajectories passing through each lake. This dataset can provide basic data for global lake/reservoir monitoring and can also be used to study the impact of human activities and climate change on freshwater supply in lakes/reservoirs.
