A full view of the Managawa Dam. The dam lake is Lake Manahime, which was named after a local legend.

 

On National Route 157 heading for Gifu from Ono City, the dam with a beautiful arch-like curve appears at the side of the road. When Fukui was hit by heavy rain and severely damaged along the Asuwa River in July 2004, the Managawa Dam and its upstream Sasogawa Dam were very effective for flood control and no flood damage caused in the Mana-gawa river area. So it cleared the way for resuming of construction of Asuwa-gawa Dam, which had been frozen.

 

An energy dissipator located directly below the dam and a fountain (a round spot around near the center of the upper part of the photo)

 

The day I visited the dam, it was discharging water from the small discharge valve on the dam body, so the fountain wasn’t working.

 

The emergency spillways at the center of the crest gate are a quadruple radial gate.

 

All the gates get together at the center of the dam body viewed from the downstream side
