An intensive Planktothrix rubescens bloom occurred in the Vrutci multipurpose reservoir in 
December 2013, disrupting the regular water supply in the Town of Uzice for 43 days. The 
reservoir was formed in 1984 at 621 m altitude. It has a volume of 50 million m3 and a 
maximum depth of 60 m. In the last 20 years, the water quality was monitored only once a 
year, making the determination of the causes of the algal bloom very difficult. Monthly 
monitoring of the phytoplankton population and basic physicochemical parameters was 
conducted during 2014. During winter circulation, TP and Chl a were uniformly distributed, with 
average concentrations of 40 μg/L and 15 μg/L, respectively. During thermal stratification, 
phosphorus was accumulated in the metalimnion, reaching a maximum concentration of 180 
μg/L at 6 m depth in the near dam profile in August. The abundance estimate range was from 
72 cell/mL in September to 251920 cell/mL in June. The biomass estimate range was from 4,5 
µg/L in September to 10239,5 µg/L in July. The total share of P. rubescens in the 
phytoplankton population reached its maximum (99,74%) at 6 m depth in January and the 
minimum value (17,13%) was observed in September.
