The current work is designated to investigate the Physical – Chemical parameters and water quality of Shanigaram a fresh water reservoir in Siddipet District of Telangana Sate. To evaluate the quality of water of this reservoir, physical and chemical parameters were studied and assessed over a span of two years, from September 2019 to August 2021. Water samples were gathered from two distinct reservoir stations and examined using conventional laboratory methods and procedures. Various Physical- Chemical parameters such as Temperature, pH, Turbidity, Total Dissolved Solids, Tota Hardness, Alkalinity, Chlorides, Dissolved Oxygen, Biological Oxygen Demand, Chemical Oxygen Demand, Phosphates, Sulphates and Nitrate were studied. These results revealed that the Physical- Chemical parameters of this fresh water reservoir was within the tolerable limits and can be utilized for household, irrigation, and aquaculture purposes.
