The catalog contains data about water management status of river Raša watercourses, downstream from Potpićan Bridge, situated in Raša and Krapan valleys in Istrian county. The results of a basic analysis related to the river regulation degree and the assessment of the existing river regulation are presented in the research on the status of Raša river torrential flows. In order to create the catalog, the research included three groups of activity: the collection of available documentation, the evaluation research in the field and the processing of collected data. The catalog consists of descriptive part, an evaluation form and the photo documentation. The observed area is divided into three torrential flow areas with a total of 24 significant torrential watercourses. The research analyzed the following basic elements: tributary basin (site vegetation, possible erosion or landslides, the presence of a road and urbanisation), general watercourse information (quantity and visibility of headwaters, arrangement, activity and the state in which watercourse is found), rugulated parts of tributaries (number, type and desription of regulations), unregulated parts of tributaries (description and state of it) and the tributaries confluence. The last chapter of the catalog contains obtained results on the tributaries regulation degree and the assessment of the existing river regulation.
