Abstract: Assessment of surface water quality is a fundamental and important technique for sustainable management of water resources. The aim of this study is to evaluate the lake water quality of the Bhavnagar region. The findings will support effective water management in the research area for a variety of future demands, including irrigation, industry, and river conservation. Environmentally significant variables were examined, including physio-chemical parameters (PH, color odor, test, Turbidity, calcium, hardness, total dissolved solids, chloride, magnesium, sulphate,). The results were contrasted with the BIS and WHO's accepted upper limits. All of the water quality metrics have been determined by correlating various parameters and comparing them with BIS, and the variations in various parameters were statistically significant when compared to the monthly seasonal variation in a lake. The QGIS software through Interpolate Map of The Water-quality parameters indicate that lakes Water is safe for Drinking Purpose
