Water resources are vital to life as we know it. There aren’t many freshwater resources in Nelamangala Taluk, Bengaluru Rural. Thus, it is imperative to use water resources—especially lakes—in a sustainable manner. To determine the quality of the water, physicochemical analysis is required. By evaluating the physicochemical characteristics of lakes in the Anchepalya Lake in Nelamangala Taluk Bengaluru Rural, this study aims to monitor the quality of water for its sustainable use. Water samples for the current study were gathered from the study spots at four separate locations during varying seasons. Using accepted techniques, the physicochemical parameters—temperature, pH, dissolved oxygen, dissolved carbon dioxide, alkalinity, hardness, and T.D.S.—were measured. It was discovered that the dissolved oxygen ranged from 5.2 mg/L to 7.9 mg/L. The range of the dissolved carbon dioxide was 32–50 mg/L. between 120 and 330 mg/L was the range of alkalinity. The temperature varied from 21 to 32 degrees Celsius. Between 58 and 120 mg/L was the range of hardness. At several locations, seasonal changes in the physicochemical characteristics were noted. The current study’s observations have highlighted the necessity of increasing public knowledge of water conservation and management.
