 abstract={The paper presents the results of studies of sanitary microorganisms' vertical distribution in pelagial and profundal waters of Lake Wigry against the background of thermal-oxygen relations and the presence of a chosen chemical compound in the annual cycle. Total Viable Count at 20°C (TYC 20°C) and Total Viable Count at 37°C (TYC 37°C) were used as indicators of pollution, while Total Coli (TC), Faecal Coli (FC) and Faecal Streptococcus-Enterococcus (FS) - as indicators of the sanitary state. Water samples were collected from 3 sites situated in the centre of the lake. Pelagial and profundal waters showed a little degree of pollution. Higher bacteriological pollution was found in some of waters samples from Lake Wigry at site I in the vicinity of the mouth of the Czarna Hańcza River. The most numerous sanitary microorganisms were detected at the deep from I to 5 meters and above the bottom sediments. Number of FC bacteria was only higher at the depth of 5 meters and deeper. An important positive correlation was noted between temperature and TYC 20°C as well as TYC 37°C, while negative between TC also FC during the whole study period. The oxygen content was correlated negative with TYC 20°C, TYC 37°C and FS. The depth was correlated negatively with TYC 20°C only.},
