“…Carlson firstly proposed the trophic state indices (TSI) to determine eutrophication level of lakes using TP, Chla, TN, COD Mn, and SD as major parameters [9]; subsequently, TSI have been widely used in lakes and reservoirs [10][11][12][13][14][15][16]. Cunha further developed a method, proposing the modification of the Carlson's index to evaluate tropical/subtropical reservoirs [17].…”

A B S T R A C TReservoirs have been widely constructed all over the world in recent years to alleviate the shortage of water resources. Nevertheless, the assessment method of water quality and its trophic status needs to be developed. In this study, water quality parameters of a newly constructed shallow reservoir were regularly monitored for a period of two years, which is used as a major drinking water source of Shanghai, China. Furthermore, the trophic state indices of the reservoir were investigated based on literature and evaluated with the two-year field data. The results indicated that the studied reservoir is reaching the mesotrophic-eutrophic boundary, where further nutrient enrichment could cause water quality degradation; total phosphorus is the limiting nutrient for algal growth in the studied reservoir. Results of the study can help operators understand change and status of water quality of the reservoir and provide valuable data demonstrating variation of water quality indicators and trophic characteristics in shallow reservoirs or lakes.

“…Threat of progression of lake eutrophication was assessed on the basis of the rate of eutrophication; the calculated real load was compared with the permissible and excessive load according to the hydrological model of Vollenweider (1968) which is widely used in limnology and has been adopted to investigate various groups of lakes in Poland (e.g. Uchmański and Szeligiewicz 1988;Kubiak 2003;MGGP and IOŚ 2010;Bajkiewicz-Grabowska et al 2011;Jarosiewicz et al 2011).…”

“…Intensive eutrophication leads to a significant decrease in the usefulness of water for the economy (industry, municipal services), recreation and sustainable fishery (Kubiak 2003;Kubiak and Tórz 2005;Kubiak et al 2012;Górniak et al 2016;Sieńska et al 2016). Eutrophication as the most significant cause of disruption of lake ecosystems (Vollenweider 1989;Jonge et al 2002) explicitly concerns the lakes of Western Pomerania (Kubiak 2003;Jarosiewicz et al 2011, WIOŚ 2016.…”

Abstract:The largest lakes of the River Tywa basin i.e. Strzeszowskie, Dołgie, Swobnica and Dłużec (north-west Poland, West Pomeranian Lakeland) were studied in the period 2008-2013, usually in a six week cycle. The aim of the study was to determine the degree of anthropogenic pressure on the lakes. Anthropogenic pressure was assessed against the natural vulnerability of lakes to degradation and the actual rate of eutrophication, with particular consideration of the catchment areas. Catchments of the studied lakes were classified as III class -catchment with moderate possibility of matter supply to lakes. Lakes Swobnica and Dłużec are characterised by low resistance to degradation. Lake Strzeszowskie is categorised as having moderate resistance and Lake Dołgie is non-resistant to degradation and highly susceptible to external pressure. The rate of eutrophication of lakes Strzeszowskie and Dłużec was found to be moderate, whereas lakes Dołgie and Swobnica show a high rate of eutrophication. The analysis of nutrient loading reaching the waters of the aforementioned lakes shows that the main area source is arable land, and the fundamental point source is the inflow of river waters to each of the analysed reservoirs. Nutrient loading supplied by the river is several times higher than area load. Such conditions require protective action to be taken within the catchment area and particularly, intensive implementation of good agricultural practice. In the studied lakes, there is a significant predominance of incoming nutrient loadings over dangerous and admissible loads.

“…While the methodology for measuring phytoplankton productivity is advanced and simplified long time ago (Vollenweider, 1969;Carlson, 1977Carlson, , 1991 the unified estimation of productivity of both phytoplankton and macrophytes together is still a difficult task (Canfield, 1984) due to the tedious nature of macrophyte measurements, heterogonous, diverse character of wetland biotopes and strong influence of varying hydrology. Nevertheless, the compiled data of nutrient concentrations, main photosynthetic pigment, and water column transparency for several years by application of wide spread methodology for trophic status estimation (Havens, 1994;Gibson et al, 2000;Jarosiewicz et al, 2011;Tosheva and Traykov, 2012;Pęczuła et al, 2014) give the opportunity to get insight into main trophic characteristics and differences between Hungarian (middle Danube) and Bulgarian (the Lower Danube) wetlands.…”

The phytoplankton limitation conditions in a few Bulgarian and Hungarian wetlands and in two more sampling sites, one for each Danube stretch, were investigated by means of trophic state index of Carlson (1977) for phytoplankton chlorophyll-a (CHL), Secchi disk depths (SD), total phosphorus (TP), and total nitrogen (TN) concentrations. Phytoplankton of both river sites was not limited by non-algal turbidity, nor was they phosphorus and nitrogen limited. In summer months the studied wetlands were predominantly nitrogen limited, while in spring and autumn limitation by non-algal turbidity prevailed.
