Lakes have played an important role in the history of Bengaluru; these were the primary sources of drinking water and irrigation in the last two decades. Due to the boom in the IT and related sectors in the silicon valley of India, has created an acute stress on the natural resources and infrastructure of the city of Bangalore with exponential growth in population. Bandematta is located in southern part Bangalore metropolitan. An attempt has been made to ascertain the Temporal Variation of water quality parameters; present study was carried-out for one year for four seasons (January 2013 to December 2013) as prescribed by Indian Meteorological Department. Seasonally the water samples were collected to analyse different physical and chemical parameters by following the standard methods of APHA (2005). Temporal variations were recorded, analysed and compared with standards and the pollution status was investigated. High levels of EC, TDS, BOD, Nitrate-Nitrogen and Total Hardness was recorded at an average of 1387.50 µS/cm, 912.43 mg/L, 4.45 mg/L, 12.73 mg/L and 342.93 mg/L respectively. Sodium and potassium were also in excess concentrations and that reflects on the agriculture. The results revealed that there is heavy organic load in Bandematta Lake. High levels of variations in various physico – chemical parameters were recorded due to anthropogenic activity and discharge of wastewater. The Temporal Variation of water quality parameters recorded is alarming and if it is going to continues for the Bandematta Lake, it will be difficult to sustain.
