摘要：The Rupa lake is the third largest and heavily tampered lake of Pokhara Valley. Physiochemical parameters like, water temperature, pH, dissolved oxygen (DO), total nitrogen (TN) and PO 4 -P and biomass of aquatic macrophytes were analyzed during pre and post-monsoon. Biomass ranged from 27.25g/m 2 –389.25g/m 2 throughout the experimental period and the highest biomass was observed during post-monsoon period. Regarding the growth form, the highest biomass was represented by emergents (251.16 ± 95.16g/m 2 ) and lowest biomass by submerged species (48.39 ± 7.27g/m 2 ). The lake can be categorized as eutrophic. J. Nat. Hist. Mus. Vol. 26, 2012: 80-87
