The overturn occurred during the early dry, cold season while the stratification was pronounced in the late dry- and the rainy-season. Anoxic conditions in the hypolimnion lasted about 9 months. The annual mean concentrations of chlorophyll-a were below 4 μg/L in 1998, 1999 and 2001, however, over 5 μg/L in 2000 and 2002. The highest picoplankton (TPP) values were found during mixing and early stratification (January-March). The minimum numbers were present during late stratification (October-November). The maximum TPP were observed within the layer 0-20 m, which corresponded to the epilimnion during the stratification period. Neither the thermocline nor the deep chlorophyll maximum showed an elevated TPP concentration. In the hypolimnion, TPP numbers were low apparently as a result of the long period of anoxia. Notwithstanding autotrophic picoplankton contributed even up to 30% of TPP. Pracoviště Biologické centrum (od r. 2006) Kontakt Dana Hypšová, eje@eje.cz, Tel.: 387 775 214 Rok sběru 2010
