Enumeration of phytoplankton and the estimation of physico-chemical parameters were carried out in Gattla Gollahalli wetland during the year 2014 -2015. A total of 45 species of phytoplankton under 30 genera belonging to five different groups were identified. Among the phytoplankton groups identified Chlorophyceae with 33.33% dominated the other groups followed by Bacillariophyceae [26.67%], Cyanophyceae [24.44%], Euglenophyceae [11.11%] and Desmidaceae [4.44%]. All the groups of phytoplankton recorded their maximum density during summer season except Euglenophyceae which recorded its seasonal maxima during monsoon. Seasonal averages of physico-chemical parameters have been worked out along with mean and standard deviation. Chlorophycean and Cyanophycean indices of Nigaard’s trophic state indices indicate that, the wetland is eutrophic. The compound quotient value of Nigaard also confirms the eutrophic condition of the wetland. The inter relationship of the physico-chemical parameters is statistically evaluated using Carl-Pearson correlation and is discussed in the text.
