Water Quality in Main Dam Reservoirs in Poland

This chapter presents the analysis of data on water quality for 22 selected dam reservoirs in Poland. The conditions of water quality have been described based on available data. The characteristics of physical, chemical, and biological parameters have been presented, and ecological status, chemical status, and the overall status of reservoirs was assessed. As a result, good ecological status was established for 13 reservoirs and good chemical status for 8 reservoirs. However, the overall classification points to good water quality of only 6 dam reservoirs located in the Carpathians, in upper sections of rivers. Other studied reservoirs have a bad quality of water. The possibilities of modern continuous monitoring on one of the dam reservoirs have also been presented.
