Guthia taal is a large, shallow and horse shoe shaped wetland of tarai region of eastern U.P. The seasonal variation of phytoplankton density and diversity were studied for a period of one year. In the present study total 31 genera of phytoplankton were identified. Out of 31, thirteen belong to Chlorophyceae, 10 Bascillariophyceae, 6 Cyanophyceae and 2 Euglenophyceae. The annual density shows that Chlorophyceae dominates and constituted 51.57% of the total phytoplankton population was followed by Bascillariophyceae (27.37%), Cyanophyceae (16.45%) and Euglenophyceae (4.61%). However, the overall phytoplankton was found maximum in summer, medium in winter and lowest in monsoon season.
