table of contents

From the center of Sendai city, head towards Akiu Kawasaki via National Route 286.
Lake Kamafusa is a beautiful lake that stretches out near the border between Sendai city and Kawasaki town.
The Kamafusa Dam we will introduce today is a concrete dam that serves the role of supplying water from Lake Kamafusa to Sendai and other cities.
In recent years, Kamafusa Dam has begun to attract attention as a tourist spot.
We will introduce its highlights.
What kind of dam is Kamafusa Dam?
Kamafusa Dam collects water from the Taro River, Kitagawa River, and Maekawa River upstream of Lake Kamafusa, and provides a stable supply of water to downstream areas, including Sendai.
The water is used for a wide range of purposes, including drinking water, agricultural water, and industrial water, and the water released from the dam is used to generate hydroelectric power, providing electricity to the surrounding area.
It also serves as a flood control facility, controlling the inflow of water by opening and closing the gates to a maximum of 917.6 kiloliters per second on July 11, 2002,
protecting downstream areas from flooding.
Kamafusa Dam, which also supplies tap water, is also committed to preserving its water quality. The
mechanism behind this is the diffused aeration circulation system.
This is a device that releases air bubbles from the bottom of the lake, blowing up the cold water from deep within and preventing the temperature near the surface from rising.
If the temperature near the surface rises, plankton will grow, so aeration helps lower the water temperature.
Dams as educational facilities

There is also a museum for disaster prevention education on the Kamafusa Dam site.
There are exhibits explaining the overview and role of the dam, and local elementary school students can participate in hands-on learning here.
Junior high school students can also participate in hands-on learning at the management center as part of their work experience. Adults
can also enjoy the corner introducing the history of Kamafusa Dam, aerial photographs of the surrounding area, and the flora and fauna that live in the area.
Recently, it has become part of infrastructure tourism, a tour that involves seeing various types of infrastructure, and it is possible to tour the dam while receiving an explanation about it
Highlights of Kamafusa Dam
・Beautiful nature

One of the attractions of Kamafusa Dam is the beautiful scenery that surrounds it
The view from the museum's observation deck is so beautiful that you'll want to capture it on camera no matter where you look
As they are particular about preserving the water quality, the sparkling surface of the lake is indescribable
You can also look through the free telescopes provided to observe the sparkling lake surface
・Bubbles erupting on the lake surface
The aeration circulation system mentioned above is actually a device that is not often seen in dams. A
circulation system is one that sprays water like a fountain.
However, in the case of the aeration circulation system at Kamafusa Dam, what you can see when the system is running is bubbles spewing out onto the water surface.
This circulation system is rare even in the Tohoku region, and among the national dams in Miyagi Prefecture, it is the only place you can see this sight.
You'll be lucky if you see the system running, so be sure to go and take a look!
・Once a year, we visit the inspection gallery
At Kamafusa Dam, an event is held once a year where you can tour the inspection gallery.
Since Kamafusa Dam is not developed as a tourist dam, this is a very valuable opportunity to experience the real atmosphere of the site.
At this event, which is held every July, you can also take a patrol boat around the lake, so if you have the chance, please visit.
・Dam cards, dam curry
Do you know about the dam cards that are distributed at dams across the country?
Dam cards were distributed at an event called "A Season for Getting Familiar with Forests and Lakes" held in 2007.
In Miyagi Prefecture, only three dams have cards with a uniform design across the country: Kamafusa Dam, Shichikashuku Dam, and Naruko Dam.
As of October 2017, they are still available, so ask the museum staff for more information!
Additionally, restaurants in the surrounding area serve dam curry inspired by Kamafusa Dam
Among them, Kamoshika Chaya's Kamafusa Dam Curry is an elaborate dish in which the condiments and curry sauce are stored in a dam-shaped ceramic container, so why not stop by on your way back from Kamafusa Dam?
