The character of structures for water impoundment entails the necessity that these structures should be particularly well inspected and the data obtained in the process of control measurement and observation should be used to prepare the safety assessment of the structure. Measurement techniques used for the inspection of water impoundment structures should be improved along with experience gained in this area. In this paper a possibility of addition of terrestrial laser scanning, allowing quick and automatic determination of location, geometry and features of a surface of the objects, to foregoing methods was analysed. Research carried out for Solina-Myczkowce Dam and Rożnów Dam proved that observations acquired using terrestrial laser scanning can be used to supplement basic diagnostics conducted to inspect and assess the technical state of dam constructions.
