Summary
Amaravathy Reservoir in Madras State has a visible bloom of blue green algae throughout the year. Though thermal stratification is absent or rare, biochemical stratification occurs frequently. Oxygen depletion in hypolimnion is common and oxygen deficit is high. Vertical variations in pH were noted often. Nitrate and phosphate were absent. High silicate content was noted at times. Primary production was high in this reservoir. Growth of fish was found to be very good.
