First part of this thesis deals with charakteristics of natural conditions on the water reservoir Žermanice, where surface water sampling and subsequent analysis took place. In next part I deal with bathing water in Czech Republic and other states and their inclusion in the legislation.

The fourth part focuses on the processing of the resulting data from the Odra River Basin from 2012-2016 and from my own measurements from the turn of 2017/2018, the temperature and conductivity, the water reaction, the amount of oxygen, the total phosphorus and the phosphates were monitored in both cases.In conclusion, I justify the reason for eutrophication at water tank Žermanice.
