The Garonne frequently leaves its bed; the most catastrophic floods were recorded in 1770, 1856 and 1930.
The Garonne is an important breeding area for sturgeon and also for the migration of Atlantic salmon.
One tributary of the Garonne, the Dropt, is particularly sensitive to eutrophication, but globally the water quality of the Garonne is between good to very good.
Deeply indented by the valleys of the Dordogne, Lot and Tarnrivers, it is a mostly agricultural region embellished with delightful villages where time seems to pass a bit more slowly.
On the banks of the GaronneRiver, the regionÂ’s capital offers many cultural opportunities in addition to a number of architectural jewels: Place du Capitole, Saint-Sernin Basilica and the Jacobins Cloisters.
