The project to build a barrage on the Oder at Malczyce came into being after the flood of 1997. As part of it, a 75m-long three-flap weir and a 256m solid weir were built. A single-chamber lock of Class Vb parameters, with a length of 190m and width of 12m, was built. Fish ladders were made, along with a water power plant with an installed capacity of 9,000 kW. The power plant will be launched next year and will generate an average of 50,000 MWh per year. The Malczyce Barrage also protects the Brzeg Dolny Barrage from underwashing and loss of stability. Moreover, it restores the original water table and prevents the excessive drainage of the adjacent areas. It contributes to suppressing erosion processes in the riverbed downstream from the barrage.
The project is one of the important tasks in the 2006 Programme for the Oder, a multiannual modernisation programme for the Oder Water System. Its main objectives are to improve flood protection on the Oder, maintain and develop inland water transport and power generation-related use of rivers.
Alongside the study visit, an IWW E70 Working Team meeting was held in Wroclaw. The main topic was to discuss the conceptual work for the IWW E70 alternative route study and to organise the IWW E70 and What Next conference.
The members of the IWW E70 Team thank the management and staff of the Regional Water Management Authority in Wrocław for their help in organising a visit to the Malczyce Barrage.
