The Polish Waters State Water Holding informs that the Racibórz Dolny Reservoir (Silesian Voivodeship) has ended its operation in the flood damming mode. It was approximately 80 percent full and captured the entire flood wave from the Oder. This minimized the effects of flooding on the inhabitants of three voivodeships.
Flood waters from the Oder began to flow into the normally dry reservoir early morning on September 15.
On Sunday, September 29, Wody Polskie announced that the reservoir had ended its operation in flood damming mode. In total, it absorbed approximately 147 million cubic meters of water, i.e. approximately 80%. its flood capacity.
Polish Waters: captured the entire flood wave
“By activating the reservoir at the optimal moment, it captured the entire flood wave. (…) The operation of this hydrotechnical facility minimized the effects of flooding on the inhabitants of three voivodeships along the Odra River: Silesia, Opole and Lower Silesia,” said Wody Polskie.
Now the tank will be tidied up and will undergo an assessment of its technical condition and safety.

It was built on the site of the village of Nieboczowy
The Racibórz Dolny reservoir was built in 2020. It was built in place of the village of Nieboczowy, which was moved a few kilometers from its previous location (the official opening ceremony of the new village took place on September 8, 2019).
Thanks to the relocation, as we wrote in mid-September, the residents now did not have to worry that their village would be destroyed by flood, as it happened in 1997.
The water level has stabilized
However, when it comes to the flood situation, according to the announcement of Polish Waters, currently the water level in the area of the Mała Wisła and Upper Odra has stabilized, remaining below the warning levels.
The technical condition of the flood embankments is being inspected, as well as the losses caused by the flood are being estimated. Any noticed irregularities can be reported by calling the 24-hour telephone number: 22 470 10 01.
Prohibition of using embankments
The ban on using flood embankments in the area of the Regional Water Management Board in Gliwice has been extended until October 6.
“The ban covers movement on the embankments: on foot, on wheels, using any motor vehicles, etc. The ban does not apply to crisis management services, as well as other units and institutions established to protect against the effects of floods,” said Wody Polskie.
However, after the flood waters passed, the Gliwice Canal and the Kędzierzyn Canal were opened for navigation on Saturday. The locks on the Gliwice Canal will be open seven days a week from: 6-22.
High rainfall amounts and the Genoese low
The cataclysm was caused by the cyclical Genoese low, i.e. a low-pressure system forming over the northern regions Italy and bringing high rainfall amounts to Central and Eastern Europe. In Poland, the flood destroyed towns such as Stronie Śląskie, Kłodzko and Lądek-Zdrój.
Many inhabitants of these regions lost all their belongings. The effects of the flood are being removed and losses are being estimated.
Another low is forming
“Mediterranean lows have been scattering hectoliters of rain on the lowlands and mountains from Italy to Poland for centuries, but as the average global temperature increases, the amount of water vapor in the atmosphere increases, so there will be more water discharges” – reports tvnmeteo.pl forecaster Arleta Unton-Pyziołek.
Adding that another low is developing in western Europe – Brigitta – which will give an impulse to the development of a secondary Genoese low.
