	Hydrobiological monitoring of Medard Lake in 2017 Hejzlar, Josef ; Nedoma, Jiří ; Znachor, Petr ; Seďa, Jaromír ; Peterka, Jiří The report summarizes the results of hydrobiological monitoring of Medard Lake 2017 and contains recommendations for further research activities. At the beginning of 2017, the lake was almost full, and at the end of March the last 30 cm water column was filled from the Ohře river. The ecosystem of the lake has reached its final nutrient load, which will be characterized by low levels of carrying capacity with low productivity planktonic and fish communities and specific seasonal changes in chemistry and biological parameters.

	Complex fish stock survey of Lake Most in 2017 Peterka, Jiří Aim of the complex ichthyological survey of Lake Most was to map the current state and succession of lake’s fish stock with particular emphasis put on abundance and biomass estimates of all fish species, evaluation of possible risks to the further development of the fish stock and recommendations for the lake management. Summarization of achieved results and recommendations for further monitoring are included in the presented report. Detailed record
	Complex fish stock survey of Lake Chabařovice in 2017 Peterka, Jiří Aim of the complex ichthyological survey of Lake Chabařovice was to map the current state and succession of lake’s fish stock with particular emphasis put on abundance and biomass estimates of all fish species, evaluation of possible risks to the further development of the fish stock and recommendations for the lake management. Summarization of achieved results and recommendations for further monitoring are included in the presented report. Detailed record
	Hydrobiological monitoring of Medard Lake in 2016 Hejzlar, Josef ; Borovec, Jakub ; Nedoma, Jiří ; Znachor, Petr ; Seďa, Jaromír ; Peterka, Jiří Presented report summarizes the results of hydrobiological monitoring of Medard Lake in 2016 and recommends further monitoring actions. Between November 2015 and June 2016 final flooding from river Ohře took place, resulting in enrichment of the lake ecosystem by large amount of nutrients at the beginning of vegetation season what affected seasonal development of chemical as well as biological parameters, from phytoplankton to fish.

	Complex fish stock survey of Lake Most in 2015. Peterka, Jiří Aim of the complex ichthyological survey of Lake Most was to map the current state and succession of lake’s fish stock with particular emphasis put on abundance and biomass estimates of all fish species, evaluation of possible risks to the further development of the fish stock and recommendations for the lake management.

	Hydrobiological monitoring of Medard Lake in 2015. Hejzlar, Josef ; Borovec, Jakub ; Nedoma, Jiří ; Znachor, Petr ; Seďa, Jaromír ; Peterka, Jiří Presented report is summarizing the results of the hydrobiological monitoring of Medard Lake in 2015 and recommends further monitoring actions. In 2015 the lake was not flooding from river Ohře, therefore the water level increase was realized only by precipitation and inflow from lake’s own drainage area. Furthermore, it was the first year without stocking of maraena whitefish and brown trout. Detailed record
	Hydrobiological monitoring of Medard Lake in 2014 Hejzlar, Josef ; Borovec, Jakub ; Nedoma, Jiří ; Znachor, Petr ; Seďa, Jaromír ; Peterka, Jiří Presented report is summarizing the results of the hydrobiological monitoring of Medard Lake in 2014 and recommends further monitoring actions. In 2014 the lake was not flooding from river Ohře, therefore the water level increase was realized only by precipitation and inflow from lake’s own drainage area. Forming of fish stock was realized according to stocking plans. Detailed record
	Hydrobiological monitoring of Medard Lake in 2013 Hejzlar, Josef ; Borovec, Jakub ; Nedoma, Jiří ; Znachor, Petr ; Seďa, Jaromír ; Peterka, Jiří Presented report is summarizing the results of the hydrobiological monitoring of Medard Lake in 2013 and recommends further monitoring actions. In 2013 ongoing flooding of the lake from river Ohře had the main effect on the monitored parameters affecting the overall trophic level and having the cascading effect through the trophic pyramid.
