Barrage de Poses, Navigation dam and lock system on Seine River in Poses, France
The dam at Poses is a lock and barrage system on the Seine that allows boats to pass and manages water flow. The structure includes multiple water passages built from concrete and steel.
This dam was built in the late 1800s to help boats move along the Seine. It opened in the summer of a year near the end of that decade.
The observation chamber lets visitors watch fish passing through the river in their natural way. This combines the working dam with a chance to see what actually lives in the water.
The site sits along the river where the public can easily watch the operations from the bank. Different spots along the site offer different views of what happens at the facility.
Windows below the water line let visitors see fish moving through the lock in real time. These underwater viewing points give a rare glimpse into how the barrier handles wildlife crossing.
