Overflow levee,越流堤防

This spot called "Tanaka-chosei-ike" which is a large scale pond of river flood regulating and with 1,100 hectares. The name is pond, but it is actually almost rice field.
This is so-called in the national policy.
In Japan, there are many ponds by the rivers called regulating pond.
This Tanaka-chosei-ike has with the 440 meters length Tone River dike, about 3 meters lower than the normal dike, and when this rivers floods, the water overtopping this low dike into the flood regulating pond.
This is to prevent many towns from flood along the Tone River.
