Flood Control Measures - the Vltava Riverbed Modification and Cleaning

Flood control works to the Vltava riverbed will take place from April 2009 to June 2010. The main construction works involve cleaning and widening of the current riverbed of the Vltava in Cesky Krumlov in the part between Mrázkův mlýn and a former weir at U Jatek. This reconstruction will bring limitations for people going down the river on boats, but the overall traffic on the river will not be restricted. There will be increased traffic of heavy duty trucks and higher level of noise and dust at the construction works exists. In summer season, the river mass removal works may cause unpleasant odour.  Český Krumlov town policy is to minimize possible negative impacts to everyday life in the city through continues communication with Povodí Vltavy, the  investor.
