Abstract: The study was conducted near bridge up to Wah Garden from 1^st June 2000 to 31^st May 2001. Algal samples were collected by phytoplankton net, pipettes, handpicking, etc. and water samples by Nansen bottles for the study of physico-chemical properties. Algae were preserved in 4 % formaline solution and found to contain 172 species belonging to 79 genera of 10 phyla: Cyanophyta (47 species & 17 genera, 27.32 %), Volvocophyta (53 species & 25 genera, 30.81 %), Chlorophyta (7 species & 5 genera, 4.06 %), Bacillariophyta (39 species & 18 genera, 22.7 %), Chrysophyta (2 species & 2 genera, 1.16 %) Xanthophyta (3 species & 3 genera, 1.74 %), Vaucheriophyta (1 species & 1 genus, 0.58 %), Euglenophyta (13 species & 3 genera, 7.56 %), Charophyta (2 species & 1 genus, 1.16 %), Rhodophyta (5 species & 4 genera, 2.9 %). The water samples were analysed for 36 physico-chemical parameters. Water was found to be rich in primary productivity as well as fish production. The ratio of D.O. was high throughout the year and water was alkaline.
