Abstract: Udhwa Lake, located in Sahibganj district of Jharkhand, represents one of the most significant freshwater ecosystems in eastern India, supporting rich biodiversity and serving as a vital habitat for migratory birds. This study presents a comprehensive limnological assessment of Udhwa Lake, focusing on water quality parameters, aquatic biodiversity, and ecological dynamics. The investigation involved the analysis of physico-chemical parameters such as temperature, pH, dissolved oxygen, biochemical oxygen demand (BOD), and nutrient concentrations (nitrate and phosphate). Seasonal sampling was conducted to determine temporal variations and their influence on aquatic flora and fauna. The biological assessment covered plankton diversity, macrophyte composition, and fish population structure to evaluate the ecological health of the lake. The findings revealed moderate nutrient enrichment indicating a mesotrophic status, with fluctuations driven by agricultural runoff and domestic waste inflows. High plankton diversity and the presence of indicator species reflected a productive aquatic ecosystem, though localized eutrophication was observed near human settlements. The study highlights the necessity for sustainable management practices to maintain the ecological balance and biodiversity integrity of the lake. Conservation strategies such as pollution control, community participation, and regular limnological monitoring are recommended for the long-term protection of this ecologically significant wetland.
