Our paper brings new infomation about long-term changes of the phythoplankton communities in the Brno reservoir with the focus on the Microcystis abundance using the semi-monthly monitoring data covering the period 2006-2012. The main aim is to extract from this long-term data set differences in number of Micrrocystis cells depending on environmental factors. The development of cyanobacteria in Brno reservoir is caused by excessive phosphate loading from wastewater treatment facilities upstream and from non-point sources along the Svratka river. It focuses management effort on upstream controls of reservoir condition. High abundance in milions of cyanobacteria cells in 1ml observed in Brno reservoir before was redused to values in the order of thousands cells in 1 ml in last two years through a combination of measures (e.g. aeration and destratification). Phytoplankton compositon was also changed and at the espense of cyanobacteria promoted the development of green algae and diatoms.
