The present study was carried out on Ghuma lake of Ahmadabad. The phytoplankton were collected, counted and were identified by using the method suggested by APHA (1995) Prescott (1970) and FRESH WATER BIOLOGY (W. T. Edmondson-1959). The phytoplanktons were counted by using Sedgwick Rafter counting cell. Different class such as cyanophyceae, chlorophyceae, bacillariophyceae and euglenophyceae were identified during the study. Among all these classes the listed phytoplankton such as Oscillatoria Sp., Tetraedron Sp., Navicula sp., Nitzschia sp. and Euglena Sp. were recorded basillariophyceae as a dominant genera in Ghuma lake.
