A lake is a large body of water, lakes the vigorous water filled in land and aquatic system performed variety of functions provide a potable water, irrigation and water for industrial uses sink for water disposal fisheries and recreation, resources etc. Are subject to contamination due to various natural and anthropogenic disturbances and all the turbulences in their water quality can assessed by calculating dissolved oxygen to judge the purpose for current water can be safely used. Naik, Futala and Sakkardara lakes was carried out by assessing water with the help of 7 parameters to calculate the quality and status of each lake. Four parameters i.e. DO, BOD, Hardness and Chloride and Turbidity were found beyond the permissible limit when compared with standards given by WHO, BIS. Results revealed that water quality of two lakes I e Naik Lake and Sakkardara is presently in extremely poor condition. Now a day many human activities creates the pollution in and around the water body due to which natural status of this lake may come in the danger zone of water pollution. In this connection the study were carried out in which water samples from different locations of three lakes were collected and analyzed for their physico-chemical characteristics to report the status of water quality of three lakes and monitoring by assessing Dissolved Oxygen level.
