Abstract
Considering the importance of Sawa lake and the scarcity of studies on it, and for purpose of providing information concerning the microbial activity. This study was conducted in order to investigate the bacterial genus and species which are likely presence in the water of the lake. We have been conducting this study from July 2012 to end of the month April 2013 i.e. , that the study was quarterly , where it was the process of isolation and identification of species and bacterial genera from water on the basis of seasons any from summer 2012 to the end of spring 2013 . the importance of economical and touris importance enjoyed by Sawa lake being considered an hydraulically important point and tourist landmark frequented by many tourists for the purpose of treatment the other hand so were selected species and bacterial genera most presence and sovereignty in water of the lake , where the percentage witnessed bacteria 100% Vibrio alginolyticus in water lake during the study period in each quarterly stations and sites that are under study , while the proportion of bacteria Proteus mirabilis 95.83 % , while the proportion of each from Staphyllococcus aureus bacteria and Escherichia coli 91.67 % .
