Sameura Dam, Gravity dam in Kōchi Prefecture, Japan
The Sameura Dam rises 106 meters high across the river, forming a substantial reservoir that supplies water to multiple regions of Shikoku Island.
Constructed in 1963, the Sameura Dam marked a significant advancement in Japan's post-war infrastructure development and water resource management strategies.
The dam earned the nickname 'Shikoku's Lifeline' due to its critical role in providing water to 3.8 million residents across four prefectures.
The facility maintains constant monitoring of water levels and downstream flow rates through a 24-hour control center that regulates water distribution.
The reservoir capacity equals 750,000 standard swimming pools, making it the largest water storage facility on Shikoku Island.
