This study was carried out in four water bodies of Bhopal for a period of 2 years. Monthly changes in physico-chemical parameters such as air temperature, water temperature, total dissolved solids, hydrogen-ion concentration, dissolved oxygen, free carbon dioxide, phenolphthalein alkalinity, total alkalinity, chloride, calcium hardness and total hardness along with bacterial occurrence were studied. The results indicated changes in physico-chemical parameters and occurrence of bacteria depending on the different seasons of the year.
