The Adour Institution is an interdepartmental public institution established in 1978 by four general councils of the Adour basin (Hautes-Pyrénées, Gers, Landes andPyrénées-Atlantiques) to manage the Adour River from its source to its mouth.

A floating barrier is installed on the Adour in a strategic position to secure floating waste and to collect it.

Collection operations on the barrage took place November 1 to 31, 3 times a week (since November 2011), every year.
