Restoration of Komaki River (Sakata City, Yamagata Prefecture)

In Komaki River, the water quality was deteriorated by urbanization and the river was named the "dirtiest river in Yamagata Prefecture" each year from 1996 to 1999. People in this area suffered from the serious deterioration of the water environment.
Under the circumstances, local residents voluntarily established "a group to clean up the Komaki River of Sakata City" and are conducting purification activities earnestly. As an approach to utilize the existing agricultural water and the agricultural facilities to improve the waterfront environment, a project to flow the purified water (ambient water) from Mogami River to Komaki River by changing the place where agricultural water is discharged started in 2007 for the first time in Japan. Thus the water quality has been improved.
