The Chiyoda Weir, which is installed in the middle reaches of the Tokachi River, was built in Showa 10 as an agricultural water intake facility for Ikeda Town's Chiyoda district, and its scale is said to be Hokkaido's number one, and in Heisei 16, it was certified as a Hokkaido Civil Engineering Heritage.
Currently, it is also playing an important role as a capture site for salmon for egg collection. The grandeur of the flowing water falling from the weir and the sight of salmon leaping on the water surface have become one of Tokachi's tourism resources.
Especially, from September to around October, the sight of countless salmon that have returned for spawning ascending the river is a magnificent thing, and it is attracting popularity as a seasonal tradition of Ikeda Town.
