Analyses of lake water taken in discrete sites along a c. 2 km transect from a 1 m depth in a eutrophic Lake Miko?ajskie revealed a uniform horizontal distribution of temperature and oxygen concentrations. Conductivity, soluble reactive phosphorus and particularly chlorophyll concentrations showed, however a marked variability along the transect. Significant correlation between pH and conductivity suggest that a local photosynthetically induced calcite precipitation may be responsible for the observed horizontal variability of these parameters. Biotic response (inferred from chlorophyll concentrations) was not coupled with chemical differences. Different temporal scales of chemical processes and phytoplankton growth are assumed to explain this discrepancy.
