The Lonar Crater is situated in Buldhana District of Maharashtra State India. It is a circular depression formed due to impact of a huge meteorite with high velosity. It contains a shallow saline lake occupying most of its floor. Part of its floor being flooded by fresh water carried through constant flow of water of unknown origin. Physico-Chemical Parameters of Lonar Crater lake were studied monthly at four sampling stations, two each of fresh & saline water in the year 2012. Salinity & high alkalinity are dominating parameters observed. The physico-chemical parame-ters of saline & fresh water Hydrobiological study include - temperature, PH, dissolved 02, dissolved CO2, alkalinity, chlorides, salinity, detection of sodium, potassium & Iron. The result of the analysis of saline water is compared with the findings of the earlier workers & shown in the tabular form. The unique findings of the Lonar crater lake includes constant PH range between 9.5 to 10.00, total absence offree CO2, and high contents of chlorides and salinity throughout the year. During the study period slight variations were recorded in the values of temperature, 02, carbonate & bicarbonate alkalinity.
