Petite mer de Gâvres
The Petite mer de Gâvres ( German "little sea of Gâvres" ) is a lagoon that is connected to the bay of Lorient in the Morbihan department in Brittany in France . The eponymous Gâvres is at the end of the raffle , which separates the sea in the south from the Atlantic . The small sea borders Port Louis and Riantec in the north, Plouhinec in the east and Gâvres in the south.
The Petite mer de Gâvres is an approximately 5.0 km long, 1.0 km wide, 566 hectare east-west oriented lagoon with a 300 meter opening at the western end. It is characterized by shallow water depths that vary between 0 and 10.0 m. At low tide the lagoon falls dry. The existence of the tidal area is closely linked to the Gâvres raffle. The promontory was originally an island. The raffle is part of a longer string of dunes that formed around 10,000 years ago during the Flemish Transgression .
In the small sea there are two islands that belong to the municipality of Riantec. The Île de Kerners and the Île aux Pins are connected to the mainland by salt marshes and mud flats. The latter is accessible on foot at low tide, while the former is connected to the Kerner district of Riantec by a road.
The lagoon is a center of tidal fishing and a bird paradise.
