The aquatic plants was composed of three groups: marginal, submerged and floating. Among the submerged aquatic plants, potamogetons was the most dominant family and had a large distribution in station IV. 37 genera were also identified from four Algae phylum. There were twelve families in benthos population, which had more abundance in station II. In study of water quality, 15 physical and chemical factors were measured. The highest amount of phosphat was 3.12 mg/1 which was seen in stations III and IV. Also the highest amount of NH4+ and N were seen in station III, probably due to existing sewage factories in this region...... | ||
