The present investigation was carried out to determine the water quality of Upper Lake in Bhopal. Upper Lake is extremely important for fisheries, drinking water, tourism and recreation, trapping, wildlife habitat, science, and education. The water samples were taken from the Upper Lake's surface between March 2019 and February 2020, covering the summer, monsoon, and winter seasons. Standard methods were used to determine the degree of degradation in water quality using physico-chemical parameters such as dissolved oxygen (DO2), total alkalinity, total hardness, calcium hardness, magnesium hardness, turbidity, pH, and temperature. The findings revealed that there is little variance in physico-chemical parameters across three seasons in the upper lake, with the majority of water parameters being in favourable conditions for fish growth and health but not suitable for human consumption.
