Abstract Sicilian reservoirs constitute the most important water resources available on island. During summer 2001, intense utilization of Lake Arancio reservoir reduced level significantly, which coincided with formation blooms formed by microcystin (MC)‐producing cyanobacterium Microcystis aeruginosa . 2003, was continuously filled and vertical stratification column maintained resulting in five to sixfold lower cell numbers M. For both years, a significant relationship between MC net production Microcysytis growth observed, implying that can be used infer concentrations water. Unexpectedly, dense MC‐producing Planktothrix rubescens occurred during winter 2005/2006 Pozzillo, Prizzi, Nicoletti, Garcia but have not been reported earlier. In this season, higher than those recorded were measured, monitoring Mediterranean drinking needs intensified winter, season usually considered less prone cyanobacterial blooms. © 2007 Wiley Periodicals, Inc.
