THE SCEINOSCOPE

At the Poses dam, there is a fish pass allowing the fish to cross the dam. This fish pass has been equipped with an observation chamber for scientific purposes, but also for recreational and educational purposes. It consists of a room with 3 picture windows, located at water level and opening onto the fish pass, which allows the observation and identification of the fish that swim up the Seine: breams, roaches, eels, lampreys, more rarely shad and salmon trout. A great observation post. Guided tours are sometimes organised.
