Bacterial biomass and production were both very high, indicating the importance of heterotrophic processes in this system. Interpretation of ETS data suggests that bacteria or "bacteria-associated organisms" are responsible for most of the oxygen consumed in the water column. Integrated bacterial production of biomass represented ca 80% of carbon produced by primary producers, thus showing that autotrophic production does not meet heterotrophic requirements of bacteria. Destratification appears to be of less importance than suggested by the physical and chemical characteristics, resulting in decrease of bacterial biomass and production by a factor of 2 in the epilimnion.
