Sevilla floodgates shut for the second consecutive time in history

Sevilla authorities shut down the Vega de Triana flooding gates along the Guadalquivir River to prevent further flooding following heavy rain and adverse weather conditions caused by Storm Leonardo. Civil protection services were on the scene early on Thursday in order to reduce flooding risks.

Officials stress that the measure was preventive, not in response to an imminent breachThis is only the second time that floodgates in history have been opened. The gates were opened for the first time in March 2025. They highlight the extraordinary nature of today’s conditions. The authorities said that lowering barriers now protects the city from sudden river surges which could occur if rain continues to be as intense as it is.

Floodgates: Function and Use

The Vega de Triana gate is a vital part of Sevilla’s hydraulic defense system. They are designed to contain riverwater and prevent it from overflowing into nearby urban areas. When the barriers are lowered, they create an airtight seal that controls the flow of Guadalquivir, reducing the risk of flooding. Emergency teams are continuing to monitor the gates in order to ensure that they work correctly.

The mayor of the city stressed that floodgates had been lowered more as a preventative measure than a reaction to flooding. To protect the public, some public spaces, such as parks and sports facilities along the river, were temporarily shut down. In addition, Local Police and Protección Civil have intensified patrols along riverbanks and urban areas near the river to respond rapidly to any localised incidents.

Storm Leonardo’s Effect on Sevilla

Sevilla has seen a rapid rise in river levels, which have reached approximately 1,600 cubic metres per seconds, but are still below the 3,000 cubic metres per seconds threshold that is considered critical for severe floods. Authorities have asked that residents remain vigilant and refrain from unnecessary travel near the riverbanks. To respond to emergencies, civil protection teams are located throughout the city. River channels and drainage have also been improved to reduce the risk of minor flooding.

Officials have stressed that the early activation is part of the risk management strategy of the city, and ensures that low-lying areas are protected even with continual rainfall. The proactive approach illustrates how preventive infrastructure can mitigate the impacts of extreme weather before they escalate into emergency situations.

Impact of Storm Leonardo Across Andalucía

Beyond Sevilla, Storm Leonardo has caused widespread disruption across Andalucía. Strong winds and torrential rainfall have resulted in thousands of evacuations. Flooding of homes has also occurred. Multiple provinces have seen emergency services respond to blocked streets, fallen trees, and power failures. Rivers and reservoirs in Cádiz, Málaga, Granada, and other areas have reached critical levels, prompting authorities to move residents to temporary shelters to ensure safety.

Some towns were evacuated because of the dangers of landslides and structural damage due to heavy rain. Sevilla, while avoiding severe flooding so far, is a testament to the severity of Storm Leonardo.

Public Alert and Preparedness

Sevilla authorities have maintained calm and highlighted that Sevilla’s flood defences are still effective, despite high river levels. Residents are encouraged by officials to stay informed and to listen carefully to emergency services. The mayor stressed that, while the situation is under control, residents should remain vigilant, especially if the storm continues.

Authorities reminded residents to cooperate with infrastructure measures like floodgates. Reporting blocked drains and avoiding travel near riverbanks will help keep the city safe during Storm Leonardo.

Continuous Monitoring

Sevilla’s civil protection teams are continuing to closely monitor river levels and the surrounding area. The authorities are ready to take extra measures if water levels continue to rise. The city is committed to proactive flood control, and the activation of floodgates shows this commitment. It protects residents and their property without causing unnecessary alarm. By acting early, the city aims to reduce risk and provide reassurance amid one of Andalucía’s most significant storm events in recent years.
