Duration of work was 8 months. Water temperature of surface water ranges 21.5°C to 32.5°C in during the study period. Variation range of the pH in reservoir water was narrow i.e. Between 7.4 to 8. In general pH of water was towards alkaline side. The DO value was ranged between 7.3 mg/l to 8.9 ppm. Dissolved oxygen is a fundamental requirement for all life. Total hardness (TH) of water range from 82 mg/l to 102 ppm. The alkalinity ranges from 112 mg/l to 130 ppm.
