This study aims to characterize the water quality characteristics of Dipang lake, which is located in the Pokhara-Lekhnath Metropolitan city in the Kaski Province. This research illustrates the seasonal and aquifer-based shifts in the lake's many water quality metrics. Although fishing, farming, and residential use were all possible within the restrictions, they were all within the acceptable range. Certain plant species, including Nelumbo lutea (Yellow lotus), can only be found near the water inflow, where the ammonia concentration is between 18 and 14.03 parts per million, and this has been linked to the water characteristics. We use normalized difference vegetation index (NDVI) to analyze the growth or decline of aquatic vegetation in the research region, in addition to the water quality parameter. It has been determined from the yearly NDVI calculations that the extent of aquatic vegetation in the research region has decreased. The rate of aquatic vegetation degradation in the research region is estimated to be 2.84 acer (7.84%).
