Bacteriological investigation had been performed for samples collected from Sawa lake. The samples included: water samples, sediment samples, crystallized gypsum, which forms the walls of the lake, aquatic plant samples (Chara sp.), Zooplankton samples (Arctodiaptomus salinus) and fish samples (Planliza abu). The bacterial analysis included, heterotrophic bacteria (HB), total coliforms (TCs), fecal coliforms (FCs), halophilic bacteria (Halococcus sp. and Halobacterium sp.), endophytic bacteria, sulfate and sulphite reducing bacteria, Clostridium perfringens and Vibrio sp.  The results showed that, only HB and halophilic bacteria were presented, while the lake was clear from any types of sulfate and sulphite reducing bacteria and pathogenic bacteria in the winter season.

Key words: Sawa Lake, Halophilic bacteria, Pathogenic bacteria.
