The influence was determined of the anthropo-pressure on the changes in the properties of the bottom sediments, with particular consideration given to the properties of humic acids formed in the sediments. The system of the Wdzydze Lakes consists of four separate basins, the northern basins being under the anthropo-pressure related to the impact of the local tourism. This study tested the bottom sediments of the Wdzydze Lake system, especially properties of humic acids extracted from the bottom sediments. The analysis of the properties of the bottom sediments showed small differences in the parameters determined. This proves the impact of local tourism on the ecosystem to be rather small so far. The results of this research suggest that a complex of positive environmental factors in a lake ecosystem can usefully outweigh the negative results of the anthropo-pressure.Keywords:
