Date of the interview: Sunday, September 16, 2012
After leaving Tamagawa Dam, we returned to Iwate Prefecture. I was the only member of the group who stayed overnight in the car, but he accompanied me for a bath at Hashiba Onsen Shin Hashiba no Yu at Roadside Station Shizukuishi Anekko, and we arrived at Gosho Dam while eating Morioka cold noodles for dinner.

Naturally, it was nighttime, so I had to take pictures of the embankment at night, but I am not used to taking pictures of nightscapes, so here's what I got... I'm not used to taking night photos, so here's what I got...left bank (of a river)(in the foreground) is a fill dam,right bank (shore)(in the back of the photo) is a gravity concrete dam.
The Gosho Dam is one of the five dams on the Kitakami River that were constructed along with the Shijushida Dam, Tase Dam, Yuda Dam, and Ishibuchi Dam under a project also known as the "Tennessee River Basin Development Authority (TVA) of Japan.
Since we were not able to visit the detailed areas, we would like to report on them when we visit again sometime in the future.
