“…2). Such an uneven distribution of cyanobacteria between the downstream (sites 1-7) and upstream (sites 8-14) sections of our research area has previously been reported as the characteristic state of this ecosystem (Wagner et al, 2009). The reason for this is the strength and direction of the wind-induced currents.…”

“…The shoreline length is approximately 54 km. The reservoir is a polymictic and eutrophic ecosystem (Wagner et al, 2009). Within the lake basin, three distinct areas are recognizable: the upper 'riverine', middle 'transitional' and lower 'lacustrine' portions, which are distinguished based on their hydro-chemical and biological parameter dynamics .…”

The occurrence of cyanobacteria is particularly characteristic of shallow eutrophic waters, and they often form massive 'blooms' that can affect aquatic invertebrates and fish. However, even a low abundance of cyanobacteria can be hazardous to aquatic organisms, due to the production of toxic metabolites. The aim of this study was to investigate the relationship between cyanobacteria and their toxicity (biological activity) towards zooplankton and fish communities, when only low concentrations of cyanobacterial chlorophyll a (less than 20 μg L -1 ) are detected, i.e. in sub-bloom conditions. Measurements were performed in Sulejow Reservoir (Central Poland), a shallow, lowland, eutrophic reservoir, in which cyanobacterial blooms occur regularly. Fish were assessed using echo-sounding (distribution) and by gillnetting (species composition). Simultaneously, zooplankton, cyanobacteria and physicochemical characteristics were studied at 14 stations situated along hydroacoustic transects. Parameters that characterized the cyanobacteria (cyanobacterial chlorophyll a concentration, the number of 16S rRNA and the mcyA gene copies and microcystin (MC) concentration) were consistently correlated (based on a principal component analysis), and the highest values were found in the downstream region of the study area. This 'cyano-complex' was also positively correlated with oxygen concentration, pH and phosphate levels, but was negatively correlated with temperature and the concentrations of nitrates and nitrites. In Sulejow Reservoir in 2013 the biomass of large zooplankton filter feeders decreased along with increasing MC concentration and fish densities, while small filter feeders did not present such relationships with regards to fish densities. Fish abundance tended to decrease at stations with a lower abundance of cyanobacteria and with growing toxic genotype copies and MC concentration.

“…Its maximum length is 15.5 km, and its maximum width is 2.1 km. At its maximum capacity (75×10 6 m 3 ), the reservoir covers 1980 ha, with a mean depth of 3.3 m and a maximum depth of 11 m. The mean water retention time in the reservoir is 30 days (Wagner et al, 2009). The reservoir subcatchment is mainly covered by agricultural land (50% arable land, 13% meadows and pastures, 1% orchards) and forests (31%).…”

“…The length of the shoreline is approximately 54 km. The Sulejow reservoir is a eutrophic ecosystem: the mean total phosphorus concentration during the years 1997-2006 was approximately 0.137 mg dm -3 , ranging from 0.013 to 1.053 mg dm -3 (Wagner et al, 2009). The dominant species of bloom-forming cyanobacteria is Microcystis aeruginosa (Kutzing), which produces microcystin-LR, -YR and -RR (Tarczyńska et al, 2001;Jurczak et al, 2005).…”

Abstract:Water is one of the main elements of the environment which determine the existence of life on the Earth, affect the climate and limit the development of civilization. Water resources management requires constant monitoring in terms of its qualitative-quantitative values. Proper assessment of the degree of water pollution is the basis for conservation and rational utilization of water resources. Water quality in lakes and dams is undergoing continuous degradation caused by natural processes resulting from eutrophication and due to anthropogenic reasons. One of the tools that are used to solve problems of surface water pollution is modelling of changes which take place in lake waters and associated water quality changes. In the last thirty years a rapid development of mathematical modelling of water resources quality has been observed. A number of computer models have been designed which are successfully applied in practice in many countries, including Poland. This paper presents an overview of mathematical models for assessment of water quality in dam reservoirs. Description of the WASP program which will be used for modelling water quality in the Sulejow Reservoir was the focal point.
