Coastal lakes act as sedimentation basins and reduce the flow of pollutants from the catchment area to the marine environment. Due to anthropogenic activities, the coastal lakes are gradually overloaded with nutrients, leading to eutrophication and posing a threat to biodiversity and human health. In this study, water quality parameters such as pH, Temperature, Turbidity, Total solids (TS), Total dissolved solids (TDS), Total suspended solids (TSS), Dissolved oxygen (DO), Biochemical oxygen demand (BOD), Carbon dioxide (CO2), Chemical oxygen demand (COD), Salinity, Orthophosphate (O-PO4), Ammonia-nitrogen (NH3–N), Nitrate–nitrogen (NO3–N), and Silicates were assessed at coastal lake of Kalamboli, Navi Mumbai, monthly from January 2024 to December 2024. Results of the study reveal that, overall, the water quality of the coastal lake of Kalamboli experiences seasonal variations. pH, temperature and salinity exhibit negative correlation with monsoonal precipitation, whereas turbidity, dissolved oxygen, and nutrients reveal a strong positive correlation. Excess quantities of municipal waste and sewage along with effluents into the lake are acting as the anthropogenic stressors of lake pollution. Pollution of the lake by organic pollutants was confirmed by lower levels of dissolved oxygen and high values of biological oxygen demand. Results of the study can be taken as a baseline for the assessment of the anthropogenic impact on coastal lakes of Navi Mumbai.
