Full view of the Naruka Weir.
There is a bridge for observing slightly above from here.
The movable Naruka Weir is located at the place where Kuzuryu River, which is the representative river of Fukui Prefecture, flows into the Fukui Plain. The appearance of the pillars is simple, which was adopted the nation's first new technology, the roller gate with hydraulic cylinder direct suspension system. It is designed based on boat and deer, which creates the distinctive scenery that harmonizes with the surroundings. Also, the weir is environmentally friendly and several fishways that have a structure according to fish are provided.
