 abstract={Sanitary and bacteriological studies of a hypertrophic Lake Bęskie, in the Masurian Lakeland carried out in the period 1982-1984, indicate that the degree of pollution of its water and bottom sediments with indicatory microorganisms varied between the sampling sites, study years, and over a yearly cycle. It is emphasized that the bacterial pollution level in the water and bottom sediments is higher near the sites of discharge of sewage from sewered settlements than in other parts of the lake. It was also higher in 1982 when the livestock in the catchment area and the amount of slurry wastes, with which crop-fields, meadows and pastures were treated, were twice as high as in 1983 or 1984.},
