Development of the Most Lake ecosystem
The research project no. TA01020592 "Impacts on microclimate, fresh air quality, ecosystems, water and soil at the hydric reclamation of abandoned lignite quarries", supported by the Technologic Agency of the Czech Republic, was going on within the year 2011-2014. The monitoring of the locality conditions with a target to record the formation and character of biocenosis and to estimate the appropriate ecological potential of locality on basis of the elements of biological quality was carried on during the continual flooding of the future Most Lake. In addition the project enabled the monitoring of water quality and the composition of originated water association within this period. Samples dedicated to hydrobiological analyses were sampled from accessible places on forming lakeshores to determine a prospective dominance of bio-indicators, state of trophy and biological index of saprobity. Character of vertical zonation, represented by deepwater samples, specifies degree of biovolume, chlorophyll-a concentration, pH and conductivity. The general information about the project, its methodology and targets was given in the Brown Coal Bulletin issue no. 1/2015. This article provides detailed results of the research in the field of the development of the Most Lake ecosystem.
