The aim of this study has been to determine the response of cyanobacteria to the lake protection and restoration measures implemented in the littoral zone of an urban lake called Jeziorak Mały. The first investigations were conducted in 1996 and were resumed in 1997-2003, 2005 and 2013, following the installation of a separator and the creation of stone accumulation sites. Long-term changes in phytoplankton cyanobacterial proportions, abundance and biomass were analyzed in relation to environmental conditions at the sites in the littoral zone (S – separator pipes, K – sites with stones and R – sites with macrophytes). Relationships between cyanobacteria and water chemistry variables were analyzed by calculating the Spearman’s rank correlation coefficient, and then with canonical correspondence analysis (RDA). The results provided evidence that water temperature, total nitrogen and iron concentration (S, R), but also PO43- in spring (S,K) were the principal factors affecting cyanobacterial development. There was a significant decrease in the share, abundance and biomass of cyanobacteria coinciding with a decrease in conductivity and PO43- following the onset of lake restoration efforts. Changes in dominant species from the ones typical in hypertrophic lakes to those typically found in eutrophic lakes took place during the research. The modifications indicated a strong initial response of cynaobacteria to the restoration measures, but the situation stabilized in 2013, when cyanobacteria returned to their previous average levels. This suggests that the introduction of lake restortation measures contributed to the lake’s improved water quality and they should be retained for efficient lake management in the future.

Trophic status of the Rusałka Lake wartes in inflow zone of Osówka Stream to Rusałka Lake reservoir in month April in years 1999, 2001, 2003, 2005, 2007 and 2010 – based on data of TP concentrations in water – was as hypertrophic determined, for except year 2007 whenas the thaw waters thinned the investigated waters that they waters were eutrophic. The added results with lead simultaneously with measurements concentrations TP the signs pH, concentration DO, COD-Cr as well as the concentrations NO3–, NH4+,TN, SRP and Ca2+and Cl – permitted on performance the general biotope characteristic of Rusałka lake water in early spring period in high exchange years and the proof, that the quality of investigated waters estimated on the basic of high exchange coefficients was stabilized, meanwhile the occurrence statistically significant differentiations the individual values of determined coefficients in next years in reference to year 1999 – was connected with changes weather influencing in changes size and date of rafting thaw waters.

Phytoplankton in the littoral and pelagial zone of the urban Lake Jeziorak Mały were studied between April and October of 2002, 2003 and 2005. The relation between the abundance and biomass of green algae and selected physiochemical water parameters, species diversity and dominants in the total abundance and biomass of green algae were analyzed. The statistically significant relationships was noted between water temperature, oxygen content, total nitrogen and the biomass of green algae at the coefficient of multiple correlation R = 0.4722. Increased the abundance and biomass of green algae were followed by a decrease in water temperature and increase in oxygen content and total nitrogen concentration during their growth in a temperature range of 10.0℃ to 18.8℃. The maximum biomass of green algae was noted in September and the maximum their abundance in October at the highest total nitrogen concentration. In the case of abundance, dominated taxa typical of plankton (Micratinium pusillum, Chlamydomonas spp., Golenkinia radiata, Golenkiniopsis sp., Koliella variabilis and Monoraphidium concortum) and biomass one – filamentous forms as a component of plant periphyton (Spirogyra sp., Stigeoclonium sp. and Ulothrix tenuissima).
