Tab. 2. Hydrological parameters for each reproductive period (RP1-RP12) in the Itá reservoir. 1 Reproductive period = RP1: spring/2000 to summer/2001; RP2: spring/2001 to summer/2002;...; RP12: spring/2011 to summer/2012. 2 AWL = Average value of the water level of the reservoir during the reproductive period. 3 VWL = Variation (standard deviation) of the water level of the reservoir during the reproductive period. 4 ASV = Average value of the storage volume of the reservoir during the reproductive period. 5 VSV = Variation (standard deviation) of the storage volume of the reservoir during the reproductive period.
