Monitoring of various water parameters of pond water and its fluctuations are useful not only to assess the natural conditions for various purpose such as fish farming, domestic purposes, but also be cautions to environmental damages. Water Quality Index is a method that enables an easier interpretation of the monitoring data. The present study was undertaken to determine the water quality of pond situated in Mansa district, Punjab during June, 2017 to May, 2018. Eight physico-chemical water parameters were evaluated from different selected sites of pond (S1 to S8). Different physico-chemical water parameters were analysed seasonally by following the standard methods given in APHA (2012) and Trivedi and Goel (1984). The values of WQI of different sites observed as S1:143.3, S2:103.8, S3:142.6, S4:127.2, S5:75.6, S6:68.5, S7:56.1 and S8:62.4 which indicate very poor water quality at site S5, poor water quality at site S6, S7 and S8 and unsuitable as S1, S2, S3 and S4 sites. This represents the water quality is highly unsuitable for commercial purpose and can be used for irrigation, industrial purpose and fish culture for suitable fish species.
