Overview
- A companion raised the alarm after the man did not resurface following a swim from a rented pedalo near Île aux Cygnes, about 300 metres off the Pâquier, on Monday.
- Firefighters, departmental dive teams (SDIS74), gendarmes and police were dispatched from the Port des Marquisats and began coordinated search-and-rescue operations.
- The Sécurité Civile helicopter Dragon 74 conducted aerial reconnaissance and divers carried out underwater searches, but rescuers had not found the 51-year-old by the latest reports.
- Authorities suspended navigation in the search area to avoid disturbing the water and cited a local depth of roughly 6–9 metres as a factor shaping search methods and excluding surface dog searches.
- The disappearance follows a separate double drowning on the same lake earlier in the week, raising local safety concerns and keeping the rescue effort under close public and operational scrutiny.
