The present study assessed the physico-chemical characteristics of the Narmada River across four selected sites (T1-T4) within Jabalpur district over a 12-month period from April 2023 to March 2024. Monthly water samples were analyzed to evaluate seasonal variations and ecological stability using standard methodologies. The parameters examined included water temperature, pH, dissolved oxygen (DO), free carbon dioxide (CO₂), alkalinity, and ammonia (NH₃). Results indicated thermally stable conditions throughout the year, with temperature fluctuations remaining within a narrow range (27.48 °C to 29.39 °C). pH levels were consistently within a neutral to slightly alkaline range (7.58-7.94), favoring biological productivity and nutrient availability. DO levels remained above the critical threshold of 6.5 mg/l, supporting a healthy aquatic ecosystem conducive to the survival of sensitive species like Mahseer. Low CO₂ concentrations and stable alkalinity values reflected a well-buffered system, while ammonia levels were minimal (0.03-0.04 mg/l), indicating negligible anthropogenic pollution. The overall findings suggest that the studied stretch of the Narmada River maintains good water quality and ecological balance, although localized human activities may still pose risks. Continued monitoring is essential for the sustainable conservation of this important riverine habitat.
