Sulfur from the deposits located in the south-east of Poland was extracted by open pit and perforation methods. Once the extraction stopped, the reclamation of excavation sites and cavity areas started. One of the excavation sites, located in Machow, was reclaimed in water direction, creating the artificial reservoir with the depth of 42 m and surface 4.5 km2 which is nowadays used to recreational purposes. The creation of water body, standardized as a bathing area, was possible thanks to isolation of the deposit layer and a proper selection of water used to fill up the reservoir. The conducted examination of the reservoir water made it possible to establish the type of the reservoir and its pollution balance. Currently, the reservoir water may be characterized as one with low contents of biogenic substances, insignificant salinity and lack of hazardous substances. The research performed indicated that the system is characteristic for typical dimictic lakes. The area devastated by mining activity was reclaimed. This reservoir is particularly important because of the lack of natural lakes in this region and small amount of places useful for water recreation. Yet, the impact of recreation can be dangerous for water quality in reservoir and cause acceleration of eutrophication processes.
