The issues with sewage disposal and surface water contamination are getting worse quickly due to urbanization, modernization, and a rise in population in Dal Lake. The water quality of Dal Lake has drastically changed over the past 40 years, making it unusable for home usage and aesthetic purposes. A lake's land usage might be expanded, which could result in a rise in fertilizer consumption and the eutrophication issue. The paper makes an effort to describe the lake's water quality situation. Several metrics, such as PH, nitrate, calcium, alkalinity and chloride have been used to evaluate the quality of water. The findings of the study have revealed that weeds cover the majority of lake water surfaces as a result of increasing nitrate and phosphorus concentrations, which cause siltation of lake water. Lower levels of dissolved oxygen in the lake water as a result of greater BOD and COD values directly endanger the lake ecosystem. Heavy metals including lead, chromium, iron, and mercury, among others, are particularly dangerous because they contaminate water or induce chronic poisoning in aquatic species. Across the world, harmful algal blooms are growing more frequent in freshwater environments. Plastic scrap pollution of water bodies, which impacts open water, shorelines, and habitats, is a growing environmental problem
