Fukashiro Dam, Gravity dam in Otsuki, Japan
The Fukashiro Dam extends 164 meters across its crest and rises 87 meters high, forming a substantial concrete barrier in the Sagami River system.
Construction of the Fukashiro Dam started in 1996 with diversion tunnels, reached full height in 2001, and completed operations in 2004.
The dam represents Japanese engineering excellence in water management, integrating traditional flood control methods with modern construction techniques.
Five free overflow openings in the main spillway can discharge 790 cubic meters of water per second, managing water flow during heavy rainfall periods.
The reservoir holds 6.44 million cubic meters of water and collects drainage from a catchment area of 43.3 square kilometers.
