Abstract
Limnological study of Upper Lake includes comparison of water quality parameters of four different sites in every month at surface and bottom level of Upper Lake, Bhopal during 2008. Water sample collected were analyzed for their Limnological characters viz. Temperature, pH, conductivity, Total hardness, Total dissolved solids, Dissolved Oxygen, BOD, COD, Total alkalinity, Chloride, Sulphate, Nitrate, Nitrite, orthophosphate, data obtained from these analysis were statistically analyzed to determine the correlation between various water quality parameters.
