Phytoplankton species belonged to Cyanophyceae, Chlorophyceae, Bacillariophyceae and Euglenophyceae. Cyanophyceae members accounted for 68% of the total phytoplankton population, followed by Chlorophyceae which accounted for 23% and the rest 9% were the members of Bacillariophyceae and a single species of Euglenophyceae. ANOVA indicated significant variation in phytoplankton species richness between the two study sites (P &le; 0.001). Significant temporal variation for Cyanophyceae density (P &le; 0.05) was also recorded. Correlation coefficients (r) among the various hydro-chemical properties and different phytoplankton groups (densities) were calculated (correlation matrix).</p> <p><strong>Key words</strong>: Phytoplankton; total coliform; fecal coliform; hydro-chemical parameters</p> <p>DOI: 10.3126/jowe.v3i0.2225</p> <p><em>Journal of Wetlands Ecology</em>, (2009) Vol. 3, pp 43-55</p> ER -
