In Saint-Étienne-de-Maurs, the Célé Lot Médian syndicate organized a full-scale flood management exercise to evaluate how local officials and technical teams would respond in a real crisis. The simulation tested the ability of mayors and staff to organize and make decisions under pressure, serving as a practical training session to improve preparedness and response strategies. The event, part of a broader initiative called "CéLot’omne," aimed to raise public awareness about water-related issues and the importance of the river in the region. The exercise, held on Wednesday, October 7, did not involve real sirens or water in the streets but created a realistic scenario to test participants' reflexes through role-playing, crisis management, and information exchange. During the simulation, mayors, technical staff, and representatives of the syndicate played their roles, responding to progressively arriving information and making decisions in response to unexpected situations. The exercise tested the local safeguard plan (PCS), a document outlining procedures for managing major risks. Anthony Veiga, a territorial project officer at the Institut des Risques Majeurs (IRMa), explained that the goal was to ensure the PCS was not just a theoretical document but a practical tool that could be used in an emergency. The scenario was inspired by heavy rainfall in February of the previous year, during which the syndicate's monitoring system allowed officials to track water levels and anticipate potential dangers. Firefighters, gendarmes, and syndicate technicians were mobilized to conduct door-to-door visits, preparing residents without causing unnecessary alarm. A room was also prepared for a possible evacuation, although it ultimately proved unnecessary. The exercise confirmed the value of training, with the mayor of Saint-Étienne-de-Maurs noting that being well-organized brings calm and allows for clear communication without causing panic. Residents reacted positively to the exercise, with some engaging with the teams afterward. The challenge now is to ensure the PCS is a truly usable tool rather than just a stored document. The Célé Lot Médian syndicate oversees flood prevention and the management of aquatic environments for nine intercommunalities and one urban community. In Maurs, a network of underground waterways crosses the urban area, with some pipelines installed in the 1960s and 1970s aging and potentially causing water level rises if blocked. Studies are underway, with initial works planned for the spring of next year. The syndicate also restores wetlands, which help retain water and reduce flood risks during rainy periods. However, microplastic particles remain in these areas, affecting the environment. With the "CéLot’omne" initiative, these issues will be brought to public attention, aiming to increase understanding of rivers, aquatic environments, and the associated risks.
