<跨style="font-size:14px">Meteoric impact crater Lonar Lake is located in Buldhana district of Maharashtra always remained as point of attraction among the researchers of different fields since many decades as it has rich chemical and biological diversity in it. Physicochemical qualities of water samples were analysed by many researchers and revealed that, the water is alkaline with high pH and categorised by high concentration of Alkalinity, Sulphate, sodium, Total dissolved solids, Magnesium, Chloride and Dissolved Oxygen. Due to this, interesting microbial complexity have been developed across the Lake. From this review, it is found that alkalinity has been decreased by nearly 19 percent, salinity nearby 7 percent and therefore its pH is seen to drop up to 6.2. This decreases is mainly due to process of sedimentation of salt at the bottom of the Lake. This has affected the living of Micro-organism. Many researches have been carried to study the nature of Lonar Lake from different fields. Therefore, an attempt is made to assemble important aspects of Lonar Lake from various fields. Conservation of Lonar Lake with proper management is necessary as it has uniqueness and beauty in itself.
