• The reservoir was built after the devastating 1997 'flood of the century' and opened in 2020, costing approximately 2 billion zlotys ($520 million).
• It covers 26 square kilometers (10 square miles) and can hold up to 185 million cubic meters of floodwater.
• The reservoir effectively mitigated the flood wave from torrential rains that brought six months' worth of rainfall in just four days.
• Areas not protected by the Raciborz Reservoir system experienced significant flooding, highlighting its crucial role in flood prevention.
