The Kanna Dam (漢那ダム) is a concrete gravity dam on the Kanna River in Ginoza, Okinawa Prefecture, Japan. The purpose of the dam is water supply and flood control. After studies were carried out in the 1970s, construction on the dam began in 1982 and it was completed in 1992. The dam is 45 m (148 ft) tall and 185 m (607 ft) long. In order to retain the reservoir, a 37 m (121 ft) tall and 500 m (1,640 ft) long saddle dam was constructed directly northeast of the dam. A fish ladder was installed on the dam during construction to assist the migration of fish, shrimp and crabs. Mangroves downstream of the dam were restored after construction and the area is a tourist destination along with a habitat for water fowl.To visit Kanna Dam and other attractions in Ginoza-son, use our Ginoza-son vacation maker tool.
Kanna Dam reviews
Found this place exploring. There is a nature trail at the bottom of the dam and an observation point above that is a few minutes drive away. A nice find. Spent a little more than an hour here before the sunset. I'll return again to spend more time exploring.
Nice little park...visiting for the burger festival.
