This diploma thesis deals with monitoring of water quality in the reservoirs which form the Litovicko- Šárecká cascade. It is a cascade of ponds, waterworks and retention reservoirs situated on the Litovicko-Šárecký stream and is composed of 9 major reservoirs. These reservoirs have different functions: from landscaping, retention, biological as well as recreation: fishing and swimming. Many of these reservoirs flow through human settlements, which have a negative impact on the quality of water within the whole cascade. The goal of this thesis is to monitor physical and chemical indicators of water as well as to determine the composition of phytoplankton populations, assess the state of water depending on the human activities in the basin and also to monitor how has the water quality changed in time and what are the main pollution sources. The water quality was determined from 11 samples collected with monthly intervals during March 2012 to May 2013. Samples were collected on all the reservoirs from the inflow, in the middle and at the outflow for chemical analysis and only from the middle for biological analysis. The following indicators were monitored: temperature, pH, conductivity, dissolved oxygen, indicators of neutralization capacity (ZNK8.3 a KNK4.5), hardness, CODMn, the concentration of...
