In waters of Dobczyce reservoir, the organic carbon content, biomass of algae and bacteria, respiration of bacteria and respiration of aquatic organisms (measured by oxygen uptake), and energetic expenditures per unit of bacterial biomass ('costs of maintenance') at the beginning of spring water bloom (May, 1996) caused by Nitzschia palea (Kutz.) W. Sm. were greater than those in the second phase of bloom. However, photosynthesis of algae was greater in the second one. In the surface layer of bottom sediments, the greatest values of measured parameters were noted in the second phase of water bloom but the 'costs of maintenance' of bacteria reached maximum values one week after of water bloom break.
