The Togagawa Dam is a gravity dam on the Togagawa River (a tributary of the Shō River) near Taikanba village about 26 km (16 mi) southeast of Shogawa in Toyama Prefecture, Japan. It was completed in June 1974. The dam has an associated 16.1 MW hydroelectric power station 5.8 km (3.6 mi) downstream near the Senzoku Dam reservoir. It was commissioned in December 1973. [1]
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by primarily using the weight of the material alone to resist the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable, independent of any other dam section.
The Shō River has its source in Mount Eboshi in the Shōkawa-chō area of Takayama, Gifu Prefecture, Japan. After flowing for 115 km (71 mi) through the northern part of Gifu Prefecture and the western part of Toyama Prefecture, it empties into Toyama Bay.
Shōgawa was a town located in Higashitonami District, Toyama Prefecture, Japan.
Gökçekaya Dam is 43 km (27 mi) north of Alpu town 45 km (28 mi) east of province of Eskişehir in central Turkey and located 60 km (37 mi) downstream of Sarıyar Dam on the Sakarya River which runs into the Black Sea. The Yenice Dam is located downstream.
The Ranapratap Sagar Dam is a gravity masonry dam of 53.8 metres (177 ft) height built on the Chambal River at Rawatbhata in Rajasthan in India. It is part of integrated scheme of a cascade development of the river involving four projects starting with the Gandhi Sagar Dam in the upstream reach in Madhya Pradesh and the Jawahar Sagar Dam on the downstream with a terminal structure of the Kota Barrage in Rajasthan for irrigation.

Yanaizu Dam is a gravity dam on the Tadami River 2 km (1 mi) upstream of Yanaizu in the Fukushima Prefecture of Japan. It was constructed between December 1952 and August 1953 for the purpose of hydroelectric power generation. It supplies a 75 MW power station with water.
Miyashita Dam is a gravity dam on the Tadami River 2 km (1 mi) upstream of Mishima in the Fukushima Prefecture of Japan. It was constructed between 1941 and 1946 for the purpose of hydroelectric power generation. It supplies a 94 MW power station with water.
Kığı Dam is a rock-fill embankment dam on the Peri River in Bingöl Province, Turkey. Its primary purpose is hydroelectric power generation and is the first dam in the Peri River cascade, serving as the headwaters. Construction began in 1998 and is backed by the Turkish State Hydraulic Works. When commissioned, it will support a 180 MW power station. Water from the reservoir will be diverted to an underground power station downstream via an 8.5 km (5.3 mi) long tunnel. In August 2015, suspected Kurdistan Workers' Party militants set fire to three cement trucks associated with the dam construction site. In January 2016, the dam was completed and the reservoir began to impound water.
The Upper Kotmale Dam is located in Talawakele, within the Nuwara Eliya District, in the Central Province of Sri Lanka. The dam feeds the third largest hydroelectric power station in the country.
The Okutadami Dam (奥只見ダム) is a concrete gravity dam on the Tadami River, 26 km (16 mi) east of Uonuma on the border of Niigata and Fukushima Prefectures, Japan. The primary purpose of the dam is hydroelectric power generation and it supports a 560 MW power station which is the largest conventional hydroelectric power station in Japan. The dam also forms the second largest reservoir in Japan, next to that of the Tokuyama Dam.
