摘要：Pond aeration is a tool that is often recommended in pond management programme. A basic understanding of oxygen’s role in ponds and lakes is crucial. The present study is undertaken to evaluate the impact of aeration units on the Physico-chemical characteristic of Upper lake situated in Bhopal. The lake receives a large amount of sewage from its densely populated habitation .The continuous input of biologically active nutrients (Phosphates & Nitrates) through inflow of sewage has changed the water body into an eutrophic lake resulting in frequent oxygen depletion. The installations of aeration units have been found to have significant impact in increasing the oxygen concentrations, changing the species diversity besides reducing the pathogenic microbial population.
