    The rotifer community of the canyon shaped Slapy Reservoir was studied over four years, from 2000 to 2003. A total of 38 rotifer taxa were identified in the pelagial zone. The dominant species, Keratella cochlearis, K. quadrata, Polyarthra dolichoptera, P. vulgaris, Synchaeta lakowitziana, Pompholyx sulcata, were similar to other reservoirs in the same area. Tychoplanktic species, which are typical for communities of upstream reservoirs, are reduced in the Slapy Reservoir. The seasonal fluctuation of rotifer abundance is characterized by a significant spring peak, clear water depression, summer peak and sometimes a lower peak in autumn.Fluctuation of the rotifer species shows a highly unified trend through the years with very low variation through the years. It results from the input of hypolimnetic water from an upstream reservoir, which erased a large part of the effect of year to year climatic fluctuations.
