Water, as the most important component of all organisms, is required for practically all biochemical actions in every way. Oceans, seas, lakes, rivers, ponds, estuaries, and other bodies of water cover over 75 percent of the earth's surface. Lakes, for example, are enormous bodies of slowly moving or still water that occupy a significant inland basin. Puzhal Lake, commonly known as Redhills Lake, is located in the Redhills neighborhood of Chennai, India. It was constructed in 1876. This lake was chosen in particular since it is a key source of water for the city of Chennai. The lake's water has previously been used for drinking and household purposes. The research was carried out to know about the pH, Turbidity, Electrical Conductivity, Alkalinity, Total Dissolved Solid, Total Hardness, Dissolved Oxygen, Chloride, Fluoride, Calcium, Magnesium, Nitrite, Nitrate, Sulphate, Phosphate, Nitrite, Nitrate, Sulphate, Phosphate, in addition, the study covers the area's biodiversity from 2019 to 2020. The work of determining the role of people in sustaining the lake's quality and biodiversity was completed.
