In the natural screes the erosive phenomena occur as a result of physical, chemical or biological factors. These processes are particularly visible in the high mountain environment. They are favored by snow avalanches, heavy rain and naturally occurring large terrain slopes. Their results are the mass movements, which may significantly change the geometry of rock debris and land relief around the scree. Eventually, the consequences of mass movements may also be landslides and rockfalls, which are dangerous to the surrounding area. Therefore, it is important to monitor and clear understand the processes taking place on the slopes. The presented works, performed with the use of terrestrial laser scanning and integrated bathymetric system, were aimed at carrying out an accurate and current bathymetric map of one of the post-glacial lakes in the High Tatras and the depiction of geomorphological phenomena occurring on the surrounding slopes in a uniform spatial reference system. The GNSS observations, referenced to the nationwide CORS (Continuously Operating Reference Station) network, and the additional surveying measurements enabled to create a coherent model of slopes and bottom of the lake in a uniform coordinate system. The authors present a methodology for obtaining the data as well as aspects of measurement accuracy. In addition, the authors present the first detailed bathymetric map of the Czamy Staw Gasienicowy Lake obtained with modem techniques.
