The paper presents selected issues related to water management of the water reservoir Młyny located at km 6 + 968 of Julianpolka river, in the municipality of Rudniki, in the province of Opole. In this paper, an evaluation concerning the exploitation of the water reservoir Młyny was carried out. The research focuses on the functions of water reservoir Młyny, which are: agricultural (use of water for agricultural irrigation), fish farming and recreational functions. The main problems of water management in it’s catchment area include: water quality (according to the research, pollution of the water that flows into the reservoir is large) and improper use of the direct catchment of the reservoir. This paper outlines proposed changes to the use of the catchment area of the Młyny reservoir, including: implementation of protection zones in the belt around the river reservoir, put of gauge sections on tributaries to the reservoir, install of measurement devices, including water gauges. The research provides important information about the condition of the Młyny reservoir. Moreover, it examines if the water is clean. This study will help with future decisions related to the use of impound water in the reservoir.
