Uhaitxa

The Uhaitxa or Gave de Sainte-Engrâce, is a torrential river of the French Basque Country (Pyrénées-Atlantiques), in the Southwest of France. It is the right tributary of the Saison. It is 15.1 km long.

Geography
The Uhaïtxa rises in the northeast of Sainte-Engrâce, in a valley dug by a glacier of the Quaternary. Quickly reinforced by several torrents, it flows through the village, then through a narrow valley, in a karstic landscape notched by many cañons as the Kakueta Canyon, accessible from the road.

After joining the Gave de Larrau, coming from the Pic d'Orhy, it forms the Saison in Licq-Athérey.
