dc.description.abstract	The sediments of Lake Turgoyak (Southern Urals, Russia) have been accumulating throughout the Late Pleistocene and the Holocene. Sedimentation is controlled by the lake's morphometry, drainage systems, vertical zoning, thermal state of the water, and wind action. Therefore, analysis of cartographic materials illustrating the area's geology, topography, drainage systems, watersheds (catchment areas) and drainage divides is relevant in this regard. Geographic Information Systems (GIS) provide specialized tools for identifying spatial patterns within a set of specified objects. Digital Elevation Models (DEMs) are valuable sources of elevation data, representing the study area as a regular grid, which enables a wide range of morphometric analysis methods to be applied in the study, including slope mapping, drainage and runoff modeling, identifying terrace inflection points, etc. This study presents a digital model of Lake Turgoyak and its surroundings. The model was developed using GIS software, incorporating available geological, topographical, and bathymetric maps. The primary data source for the model was the Copernicus DEM GLO-30, provided by the European Space Agency. Modeling of watersheds and drainage divides was conducted using the Hydrology toolset in ArcGIS Pro 3.0.2's Spatial Analyst module. According to the model, the maximum elevation in the area is 884.7 m, which aligns with topographic maps when accounting for the Copernicus DEM's margin of error. The lowest point in the model is located at 287.4 m, which corresponds to the lake's maximum depth of 32.6 m. The hydrological modeling showed that Lake Turgoyak's total watershed area spans 52.5 km2 and comprises 43 sub-areas. Four of them are large ones – those of the rivers Lipovka, Mokhovaya, Bobrovka, Kuleshovka, and Pugachyovka. In total, they account for 81% of the entire watershed area, primarily framing the lake's northwest, west, and southwest shores. Overlaying the model of the watershed on the geological map allowed for determining the composition of sediments carried into the lake. The GIS-based digital model of the Lake Turgoyak can serve as a valuable foundation for future research across various geographical and geological fields, including the climate-sensitive history of lake sedimentation.	ru_RU
