Problems of water quality and ecological potential of Lipno Reservoir in the period 1991-2012
Hejzlar, Josef ; Galindo, F. ; Krolová, Monika ; Znachor, Petr ; Žaloudík, Jiří
The research report describes the analysis of trends in water quality, external and internal nutrient loading, and apportionment of nutrient sources in the Lipno reservoir on the River Vltava, Czech Republic, during the period 1991-2012, together with a prognosis of future trends of eutrophication and possible management mitigation measures for improvement of the reservoir´s ecological potential to achieve compliance with the EU Water Framework Directive.
Drinking water reservoir Nýrsko - influence of macrophytes on water quality
Hejzlar, Josef ; Hohausová, Eva ; Komárková, Jaroslava ; Kopáček, Jiří ; Peterka, Jiří ; Duras, J.
The importance of macrophytes in P cycling was studied in Nýrsko Reservoir, an oligotrophic water body in western Bohemia. A comparison of the external P loading with the P content in macrophytes of Nýrsko Reservoir in 2004 demonstrated that macrophytes can play a significant role in P-cycling also in deep, pelagial-dominated water bodies on condition that the external P loading is low and macrophytes have appropriate conditions for their growth (mainly small extent of water level fluctuation). Nýrsko Reservoir is an apparent example of situations from limnological textbooks when macrophytes function as a stabilizer of the aquatic ecosystem with an efficient zooplankton grazing on phytoplankton allowing suitable water quality for drinking water production.
