The Dike
The lakebed of Lake Hachiro is made up of very soft, unstable ground.
During the reclamation of the lake, the sludge from the lakebed was removed and replaced with sand, and then soil was added on top.
In a way, the embankments are like they’re “floating” on the lakebed.
In the southern part of Ogata Village, there are even some embankments that are over 200 meters wide.
