ABSTRACT
The aim of this study was to collect data on the variability of dissolved oxygen content, pH and conductivity in waters of Lake Rusałka and the microbiological status of its bottom sediments following mechanical removal of the cyanobacterial blanket. Results indicate that mechanical removal of the bloom blanket from the lake surface accelerates oxygenation of its waters and growth of aerobic bacteria, mineralizing the bottom sediments and reducing pH.
