In the paper the planned restrictions in the use of land and water resources in the protective area of the Świnna Poręba Reservoir are presented, which were proposed in order to protect the reservoir waters against the degradation. There are described the impact of the protective area establishment on the documents of spatial planning in municipalities around the reservoir and the possible economic impact of the creation of such area. Additional protection of the reservoir waters shall be ensured by legal records of the Conditions of use of the waters of the Upper Vistula Region, which put restrictions on the use of the waters in the region, including also the Skawa catchment area. The introduction of these two management instruments – the protective area and the conditions of water use – makes a full protection of the reservoir against excessive loads of pollutants.
