Dam in Aichi Prefecture

1209-Oiike

Oiike is an irrigation-only earth dam located in Koda-cho, Nukata-gun, and has been recently renovated. It has just been renovated and is beautiful, and it is also an assertive dam, as you can see on the embankment. I hope the local farmers will continue to do their utmost to make the dam work as well as possible. Many cherry trees have been planted along the lakeside, making it a popular cherry blossom viewing spot. / Earth dam / 31m

1201-Chikaga Iriike

Rikigairi Pond is an agricultural reservoir located near Kotosawa Regulating Pond, and was built by the local people. It is not easy to approach the embankment, perhaps because it is cherished by the local people. The flood discharge was also photographed through the fence. I was forced to take this picture, so I ignored the level. / Earth dam / 19m

1233-Kotozawa Adjustment Pond

The Kotosawa Regulating Pond is located in Koda-cho, Nukata-gun, south of Okazaki City, Aichi Prefecture, and is a central impervious zone-type rockfill dam under the jurisdiction of the Ministry of Agriculture, Forestry and Fisheries for irrigation purposes only. Although it looks like an earth dam at a glance, it is a rockfill dam. It is also the core dam of the national Yahagigawa River Comprehensive Project, and is an important source of irrigation water for Koda Town, Kira Town, and Hazu Town. / Earth dam / 20.5m

Yomikakidam is a gravity-fed concrete dam dedicated to power generation owned by Kansai Electric Power Co. Water is taken from this dam and is then piped downstream to the Yomikakidamu Power Station. Originally, the dam was associated with Momosuke Fukuzawa, the king of electric power during the Daido Power Company era, and the power station's main building, Kakinokishimizuji Bridge, and Momosuke Bridge have been designated as national important cultural properties. / Gravity concrete dam / 32.1m

3084-Takigawa Dam

We arrived at the Takigawa Dam. Approaching from an empty main street, the embankment can be glimpsed at the end of a curve. The Taki River Dam is a gravity-type concrete dam built in the Takayama area of Iga City on the Taki River, a small branch of the Hijiki River, a branch of the Kizu River, a branch of the Yodo River system. It is a very simple, cost-effective dam of the type often seen in prefectural dams. / Gravity concrete dam / 29.8m

3335-Tongu Pond/Tongu Ike

Commonly seen reservoir type earth dam. An important dam that supports local agriculture and farmers. After leaving the Hinogawa Dam, we next headed for Tongu Pond, an earth dam that has been selected as one of the "50 Best Reservoirs in Shiga. You can see it on the left when you go south from the Hinogawa Dam on Prefectural Road No. 41, but be careful when driving as the road narrows at some points along the way. / Earth dam / 22m

1358-Hinogawa Dam

The Hino River Dam is properly a gravel fill dam (more precisely, a central core gravel fill dam), which is not made of larger stones like a rock-fill dam, but of raised gravel. The dam is loved by the local people as a place for recreation such as fishing and walking, and even though it is small in scale, it works well...that is the image of this dam. / Rockfill dam / 25m

3601-Hinogawa Wakidamu

I had intended to put them together as the Hino River Dam, but when I looked at the dam handbook, etc., I discovered that there was a side dam, and I had to sort through the photos in a hurry.... However, it is difficult to determine where the Hino River Dam begins and ends at the side dam, and since I did not intend to take these photographs in the first place, there is a possibility that my memory is mistaken. / Earth dam / 19m

1366-Zao Dam

The Zao Dam was built to secure water for agriculture of 4,986 ha of rice paddies and 225 ha of fields in Omihachiman City, Ryuo Town, Hino Town, and Higashiomi City, Gamo-gun, and is not a particularly remarkable dam. This is one of the important agricultural water utilization facilities in the Higashiomi area, so it is quietly watching over agriculture.... / Rockfill dam / 56m

3195-Yasu River Dam/Yasugawa Dam

The Yasu River Dam is a gravity-type concrete dam for irrigation only and has an old history. 50 years have passed and the dam has become decrepit, so it will undergo overall renovation, which will be completed in 2010. I like the old smoked silver dam, but a fully renovated modern concrete dam is not bad either. / Gravity concrete dam / 54.4m

The Komono Regulating Pond is a dam located in the central part of the Mie Irrigation Canal managed by the Japan Water Agency. It is an important dam that supplies water to the cities and towns of Yokkaichi, Suzuka, and Komono, along with agricultural water to the Takeya Canal, while conducting water from the Nakasato Dam and storing water from the Tamitsu River, Mitaki River, Uchina River, and Mimai River and delivering it to the main canals downstream / earth dam / 28.4m / 28.4m / 28.4m / 28.4m / Earth dam / 28.4m

The Miyagawa Regulating Pond is an irrigation-only dam owned by the Japan Water Agency, and is used for agricultural water via the Asaaki Irrigation Canal. It is located in the middle of the trunk canal of the Mie Irrigation Canal and not only stores water for its own watershed, but also conducts water from the Nakasato Dam to the Mie Irrigation Canal when there is a shortage of water. / Earth dam / 27m

2312-Sugita Dam/Suidamu

Sugita Dam is a dedicated power generation dam owned by Kochi Prefecture, and apparently also serves to reverse the peak load flow of the Nagase and Yoshino power plants located upstream. The maximum authorized output is 11,500 kW, which is the amount of electricity used by about 15,000 average households in a year. There were also some events that made me feel the good-naturedness of Shikoku. / Gravity Concrete Dam / 44m

2322-Sameura Dam

For me, this place could be a sacred place. The Hayamoura Dam was the object of my highest longing. It reminded me of the time when I first became a dam maniac and had my heart set on the Kurobe Dam (Toyama). However, unlike those days, I have seen many dams, but this is the legendary Hayamyoura Dam. I can't help but be reminded of it. / Gravity concrete dam / 106m
