The article presents application of the sonar techniques in the operational excavation Bielinek. While probing the reservoir bottom were used two methods of GPS positioning. Direct depth measurement has been checked by weights probe. The obtained results were compared with each other in order to determine the accuracy of the measurements. They were the basis for the development of a numerical model of Bielinek reservoir bottom.
