The Baïse is a river in the south of France that flows in the departments of Hautes-Pyrénées, Gers and Lot-et-Garonne, in the Occitania and Nouvelle-Aquitaine regions.
It is a direct left tributary of the Garonne.
It flows north through the following departments and towns:
Hautes-Pyrénées: Lannemezan, Trie-sur-Baïse
Gers: Mirande, Castéra-Verduzan, Valence-sur-Baïse, Condom
Lot-et-Garonne: Nérac, Lavardac
187.6 km long, the Baïse’s source is on the Lannemezan plateau towards Capvern-les-Bains, in the Hautes-Pyrénées (Pyrenees Mountains), and empties into the Garonne at Saint-Léger, slightly upstream of the confluence between the Lot and the Garonne.
During low water periods, its course is maintained, via the Neste canal, for irrigation and for the needs of drinking water supply and sanitation.
