Abstract

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 PO4-P and biomass of aquatic macrophytes were analyzed during pre and post-monsoon. Biomass ranged from 27.25g/m2–389.25g/m2 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/m2) and lowest biomass by submerged species (48.39 ± 7.27g/m2). The lake can be categorized as eutrophic.
