Water quality in the Mastnik catchment area and it`s influence on Slapy reservoir Abstract Despite major investments in remediation of waste water and reduction of fertilizers the quality of surface water on small rivers in agricultural and rural regions of the Czech Republic is still very low. Among the problematic rivers is also the river Mastník. This river runs through agricultural area of the Central Bohemian Uplands and as a right-hand side tributary it flows into the Vltava river, in particular to Slapy reservoir. According to the data of concentration of indicators coming from monitored profiles of the State public enterprise Povodí Vltavy which were completed by our own monitoring profile the quality of water has been analyzed. Furthermore, the effect of Mastník on the water quality in Slapy reservoir has been evaluated. It was discovered that the steps that are being taken, mainly construction of sewage treatment plants, are leading to gradual improvement of quality of the surface water. Nowadays the final quality of water is influenced by growing concentration of chlorophyll. This growth is caused by warmer waters and that leads to higher eutrofisation of rivers in the catchment area. The most significant eutrofisation is showing in the creek of Mastník where it's affected by Slapy reservoir. In...
