Other facilities/observations
It is said that the dam site on the left bank can be reached by passing through the "Ouenwa Silver Line," a series of 11 tunnels over a total length of 30 kilometers. There is also a prefectural road, but it is closed from the end of November to the middle of May due to snow accumulation. In addition, the "Maruyama Ski Resort" on the left bank of the downstream side of the embankment, operated by the Kitanihon Electric Power Company, is closed during the high season in February due to excessive snowfall and reopens in March, which is unusual.

Both "Oku-Towa Silver Line" and "Maruyama Ski Resort" are modeled after Okutadami Dam, and are called "Okutadami Silver Line" and "Okutadami Maruyama Ski Resort," respectively. The long tunnel and winter closure are also very similar.
