Abstract - In this study we are analyzing the water quality
about the ecosystem's resources for life support and whether or not they are suitable for human use.
of Shantigrama lake, Hassan District, Karnataka. The physiochemical characteristics of the lake will be studied and analyzed from November 2022 to April 2023 for a period of Six months. Water samples will be collected on a monthly basis from four different sample stations i.e., S1, S2, S3 and S4. The analysis was carried out for the parameters like Turbidity, Total Dissolved Solids, pH, Total Hardness, Alkalinity, Acidity, Dissolved Oxygen (DO), Biological Oxygen Demand (BOD) which gives a better understanding of the prevailing condition of the lake with respect to water quality variation w.r.t seasons. We have used Water Quality Index method given by Horton which was helpful in studying the variation of quality of water. From the observed values it can be concluded that the water quality of the Shantigrama Lake is good and with some degree of primary water treatment it can be utilized for consumptive use as well.
Natural and anthropogenic processes, such as rainfall, erosion, hydrological features, and industrial and agricultural activities, control the quality of surface water. Physiological and chemical factors determine the water quality in rivers, lakes, and reservoirs.
1.1 Objective

1.INTRODUCTION
Shantigrama Lake is situated in Hassan district of Karnataka state India (Fig. 1.1). It is surrounded by 3 villages and located along Bangalore-Mangalore NH-75. The area of the lake is 189 hectares. The water storing capacity of Shantigrama lake is 67.10 MCFT (Million Cubic Feet). The lake is mainly used for irrigation, fishing and washing purposes.
Water is a one-of-a-kind natural component that is essential to many life processes. Water is essential to the growth and survival of all living things. Due to the limited availability of water resources, water bodies are extremely valuable. The most significant factor in shaping the land and regulating the climate is water. The primary reason that natural water bodies' water quality has deteriorated is rapid industrialization and population growth. In future, there could be a shortage of fresh water because of impromptu and unreasonable double-dealing. There is expanding need for freshwater assets like compact water for local locations, water system water for farming, water for modern use in enterprises and water for hydroponics. With their irreplaceable ecological functions, social benefits, and economic value, lakes are an important inland water ecosystem. Water quality weakening in lakes has involved extraordinary worry because of its adverse consequences on friendly monetary and well-being viewpoints and has been perceived as a difficult issue at neighborhood provincial and worldwide levels. Any ecosystem's water quality tells a lot
