Vembanad Lake is a Ramsar sitethat stretches about 80 kms and covers an area of 200 Sq.kmslocated at Alleppey, Kottayam and Eranakulam districts of Kerala, India. The quality of water of this lake has to be analysed as it serves almost 55,000 ha of agricultural land. Water quality can be analysed through parameters viz. pH, turbidity, BOD, TDS, TSS etc. In this research paper, the watershed map of the study area has been created and the land is classified. The spatial distribution of water quality parameters of the Vembanad Lake has been plotted. A linear regression model has been created from the spectral reflectance values of these parameters and were analyzed. The study determined the parts of the lakethat are more contaminated than others. This study and the corresponding analysis will be beneficial in implementing steps to improve water quality and manage waste outflow into the lake.
