Presentation :
Pre-fabricated crawling gutters are used to create eel passes on dams with a low fluctuation levels. The gutter is made with polyester and covered with brushes. Brackets ensure their attachment to the vertical wall of the dam. Intermediate watershed creates the resting pool and changes the direction of the slope.
