It eventually terminates into the Abukuma River in the Ogura area of Fukushima City.

Due these floodings, the Arakawa River has changed its course multiple times.

The Arakawa River's steep descent in the Tsuchiyu Onsen area formerly caused multiple earth and rock slides.

To prevent further damage, in 1900 Fukushima Prefecture began flood control construction on the river, and in 1936 the country took over and began construction of the Arakawa First Check Dam (荒川第一砂防堰堤, Arakawa Daiichi Sabō Entei).

In 2004 the Arakawa River's flood control system was completely overhauled, and 13 new check dams were built along the main river and numerous other dams built on its tributaries.
