Fishponds in Hracholusky Reservoir drainage basin – results from screening

Series of 16 fishponds was monitored as a part of a drainage basin of Hracholusky reservoir, which is subject of a recovery project. All the fishponds were eutrophic – hypertrophic due to wastewaters from villages and little cities (including overflows from sewers) and/or due to too intensive production of “hunters ducks” – the phenomenon that is rarely mentioned.

Impact of fishponds on water quality of the Jordán water reservoir in Tábor

High eutrophication is the main factor that has recently disabled the Jordán water reservoir for water supply and recreational purposes. Large-scale dredging of sediments was done between years 2011 and 2014. Thereafter a complex monitoring of water quality has been initiated since 2015.
