When restructuring the Maladrerie site,
located upstream of the well known Lerouge Bridge,
the town of Millau decided to build a new channel
not only to make the transit of the Tarn River easier but also to develop
a white water stadium. This white water river with modular
obstacles, located in the middle of the Maladrerie sport
and leisure site, allows different levels of navigation
and does not prevent the discharge branch from assuring
the flood evacuation. A fish pass consisting of several successive basins has been
placed next to the roof gate on the right river side. The fish migration is independant
of the flow of the white water course.
