Present paper embodies the phsiochemical data of Halali reservoir which is 40 kms away from the Bhopal. Results of different physico-chemical parameters like nitrate, phosphate, DO etc. have revealed that the water quality of the reservoir stands quite well to put in use for different purposes like agriculture, aquaculture, domestic and industrial. The DO content of water varies from 6.1-9.6 mg/l indicating the suitability of water for aquatic fauna residing in the reservoir which is the source of different fish varieties like catla catla, rohu, mrigal, wallago attu, mystus, chitala etc. Transparency ranges from 76–254 cm allows the solar radiations to penetrate the aquatic system to a considerable depth desirable by the aquatic flora for photosynthesis. Concentration of nitrate and phosphate (the two key nutrients) were observed below the ESEPA’s prescribed level.
