Camargue is a place of constant exchanges between the sea and the ponds. To regulate the exchanges between these two environments, three openings (or valves) have been positioned along the sea wall. The Fourcade opening is the only functional exchange zone, continuous between the ponds and the sea. It allows the flow of water and fishes and plays a major role for migratory exchanges, wildlife, salt and water levels, fishing, fish rearing and flood management.
