Wikipedia has a page about Gironde Estuary
The Gironde ( zhi-ROND, US usually ji-, French: [ʒiʁɔ̃d] (listen); Occitan: Gironda) is a navigable estuary (though often referred to as a river) in southwest France and is formed from the meeting of the rivers Dordogne and Garonne just downstream of the centre of Bordeaux. Covering around 635 km2 (245 sq mi), it is the largest estuary in western Europe.
The Gironde is approximately 75 km (47 mi) long and 3–12 km (2–7 miles) wide and the French département Gironde is named after it. The Gironde is subject to very strong tidal currents and great care is needed when navigating the estuary by any size or type of boat.
Since 2015, the Gironde estuary has been part of the Gironde estuary and Pertuis sea Marine Nature Park.
