The present study aimed to identify suitable sources of water from the reservoir for domestic, irrigation, and agricultural purposes. Water samples were collected fortnightly from January 2022 to December 2022, at four sampling sites and were analyzed using various physicochemical parameters, such as, pH, air temperature, water temperature, TDS, chloride, total alkalinity, DO, BOD, COD, total hardness, nitrate, nitrite, phosphate, sulfate, and free CO2. The results of parameters within permissible limits, Compared with standards, BIS. All parameter results showed a significant relationship, as determined by an ANOVA test in the SPSS package. Variation in physico-chemical parameters was observed, which is useful for water quality monitoring strategies. Therefore, the water was found to be fit for human consumption and utilizable for agricultural uses. The reservoir helps maintain the health of the aquatic ecosystem.</p></abstract><kwd-group><title>Keywords</title><kwd>ANOVA-test</kwd><kwd> Manjalar Reservoir</kwd><kwd> Physico-chemical parameters</kwd><kwd> Seasons</kwd><kwd> Western Ghats</kwd></kwd-group><counts><ref-count count='' /><page-count count='' /></counts></article-meta></front></article>
