Abstract Lonar Lake is the third largest natural salt lake in the world. The lake turned pink in a span of 3 days in month of June 2020 and indicator of Lower water level, increased the temperature, low influx of fresh water body and no interference of human due to lock down of pandemic period leads to growth of Halo bacterium and Dunaliella Salina algae secrets carotenoid and due to increased of carotenoids levels which in turn led to colour change and it’s necessary to know the why this strange phenomena is happen. The main objective of this research is to assess temporal changes using NDVI was calculated using the Landsat images to determine vegetation using Arc GIS. Top of Atmospheric radiance (TOA) correction were applied. This research is based on secondary data total 6 tiles of different month were downloaded through Landsat 8 series using band 4 and 5 from USGS with 30m resolution with using the NDVI method through Arc GIS for preparing the thematic mapping and MS excel is used for preparing the graphs.
