Abstract

In the Bhavanisagar Reservoir a stable thermal stratification did not occur, but the thermal stability was fairly high. Oxygen deficits occurred frequently as well as complete anoxic conditions. Influx of flood waters improved the bottom oxygen conditions. This together with other factors indicates a high level of metabolic activity and productivity. Primary production rates were fairly high. There has been a change in fish population; some introduced species (like Catla and Labeo calbasu) have increased in the catches. It is felt that more fish could be exploited from this reservoir.
