Ghunghutta Dam, a critical freshwater reservoir in Chhattisgarh, India, plays a pivotal role in sustaining agricultural irrigation, domestic water needs, and regional biodiversity. This study presents a comprehensive limnological evaluation of the dam, focusing on the physical, chemical, and biological parameters that shape its aquatic ecosystem. Over a defined observational period, data were collected on water temperature, pH, dissolved oxygen, nutrient levels, and plankton diversity to examine seasonal patterns, ecological interactions, and potential environmental stressors. The results reveal distinct temporal variations in water quality, linked closely with climatic fluctuations and anthropogenic influences. Physical parameters such as temperature and transparency were found to affect species distribution and biological productivity, while chemical indicators pointed to areas of nutrient enrichment and potential eutrophication. Notably, planktonic communities displayed shifts in abundance and composition, serving as effective bioindicators of water quality and ecological balance. This study highlights the interconnectedness of abiotic and biotic factors in maintaining reservoir health and provides critical insights for managing aquatic ecosystems under increasing developmental pressures. By establishing a limnological baseline for Ghunghutta Dam, our findings support informed policy and conservation strategies aimed at the sustainable utilization of this vital water resource.
