The aim of this study was to ascertain the current condition of the Anchar lake water body in the Indian state of J&K in terms of water quality using some main parameters such as pH, TDS, EC, DO, and nitrates content. For the years 2019 and 2020, samples were obtained for two seasons: summer and winter. The quantitative analysis of the experimental results indicates a general increasing trend and considerable variance in nitrates content, as well as a gradual decrease in pH, indicating that the lake's acidity is increasing, but only within the basicity range, with real values approaching neutrality: TDS and EC content suggest a very favorable situation, but when the overall parameters are tested, they show a defect. Since the sampling sites were well aerated, the dissolved oxygen content showed a growing pattern, and as a result, this metric proved to be useless in deciding the overall scenario in the lake. In the winter, the longitudinal trend line indicates a 10% decrease in pH, while in the summer, it shows a 4.4 percent decrease in pH. In winters, the longitudinal trend line reveals a 6.7 percent growth in nitrate content, while summers see a marginal decline. In the winter, the longitudinal trend line shows a 7% rise in dissolved oxygen, while in the summer, it shows a uniform trend.
