Abstract: Present work was designed to study the physicochemical parameters of four lakes of Udaipur known as the “City of Lakes” of Tripura state. The studied lakes are Amar Sagar (AS), Dhani Sagar (DS), Jagannath Dighi (JD) and Mahadeb Dighi (MD). To evaluate the water quality of the lakes and to identify the pollution sources random sampling was done during the month of April, 2014. Collected samples were analyzed according to APHA (2005) for different physicochemical parameters and the results were compared with standard values prescribed by WHO (1997) and BIS (1991). Obtained results of physicochemical water quality parameters of studied lakes revealed the fact of pollution load in the lakes. Average Biochemical Oxygen Demand (BOD) as well as the value of ammoniacal nitrogen (NH3-N) is found high during analysis which conveys high bacteriological load, organic matter disposal and animal waste contamination into the lakes.
