The Shin Naruha River Dam's reservoir is used as the upper reservoir for pumped-storage power generation, and the Tahara Dam is located in the lower reservoir. On this day, I visited the Shin Naruha River Dam with my friends and then moved on to another dam, so I did not observe the dam in detail, but took this photo from along the prefectural road.

Sorry for the photos, they were taken from almost the same position 💦.

The Tahara Dam has six radial gates balanced on the crest. The two gates in the middle seemed to be under renovation.

On the right bank is the Tahara Power Plant of the Chugoku Electric Power Co. In addition to pumped-storage power generation, the plant also produces dam-type power generation.

The discharge channel of the Tahara Power Station is a bit strange: instead of flowing immediately downstream of the power station, it is tunneled underground and discharged approximately 1.4 km downstream. It is a bit of a mystery why they went to the trouble of doing this.

I can't deny that it is a little on the indigestion side since I only photographed this much, but I would definitely like to revisit if I have the chance to visit the area again.
