Shikawa Dam (四川ダム, Shikawa Damu) is a dam in Fukuyama in Hiroshima Prefecture, Japan. The dam began construction in 1974, and the project was completed in 2004. The dam has a height of 58.9 metres and a length of 251 metres.[1] The reservoir has a maximum capacity of 1,650,000 m3 and has a catchment area of 15 km2.
Development
[edit]The dam is currently managed by the Tsutsumi Takashi Office of Hiroshima Prefecture. The Shikawa Dam is a concrete gravity dam which was initiated as part of the Kamo River Flood Control Plan. The plan has a number of important functions and aims to improve irrigation and flood control in the area whilst providing water stabilization and environmental protection.[2] The artificial lake, Lake Shiroyama (城山湖, Shiroyamako) formed by the dam is at present to the north, just past the dam.[1] Takiyama castle is nearby.
The Shikawa Dam is in the upper reaches of the Kamo River. A pond dam for irrigation was originally completed as early as 1925 but underwent significant renovation between 1974 and 2004 to enable it to control flooding in the area.

Recycling
[edit]The dam also serves as a sewage treatment works with its water treatment facilities. Sludge generated by the turbines is re-used. The mass recycling of the sludge earned the dam the Merit Award for Recycling in 2002 by the Ministry of Transport even before the dam was officially opened.
