Revitalisation of rivers around Győr

The city of Győr is crossed by several rivers and canals, which flow into the nearby Danube. Due to the changing climate and conditions, average water levels have been below normal. To address this, the General Directorate of Water Management, the city of Győr and the Hungarian State have cooperated to build a water level control dam at the mouth of the Mosoni-Danube and Danube rivers near Győr. The aim was to raise the water level of the surrounding rivers by damming them, which would allow the water flowing through the city to be abundant in summer.

The process was to determine the water level to be reached, which was eventually set at the 1950s average.

The next step was to determine the appropriate water level for each season, which involved biologists, anglers, hunters and all other stakeholders.

And during the test operation period, the operation was refined to achieve the best possible conditions.

During the hot summer months, the city's microclimate is significantly improved due to the abundant water cover in the city. The higher water level has also resulted in higher groundwater levels, allowing vegetation to better withstand the heat, and improved irrigation opportunities, which have improved the microclimate of the area through shade and evaporation.

The dam was built in such a way that it does not impede fish migration or watercraft, benefiting not only the local climate, but also water sports and ultimately nature.

In addition, the dam also plays a huge role in flood management

This was an investment on a huge scale, the most difficult part of which was financing the project.
The project was preceded by a lengthy technical debate, at the end of which the interests of all stakeholders prevailed.

Climate change is forcing us to make such large-scale and costly investments. To achieve this, we need to start preparing for their implementation in advance. Public awareness must be raised, because all stakeholders must be involved.
