Tama River, with Ogouchi Dam (called Okutama Lake), completed in 1957, and with tourist facilities, has been a relaxation and recreation area for Tokyoites. But its midstream and downstream in Tokyo and Kanagawa have been urbanized as residential and industrial areas. During the high-growth period in 1965-75, its water quality was deteriorated and the variety of the water usage increased. Residents gradually needed more orderly space usage.
Recently natural life has returned to the area as the sewage system penetrated and the water quality improved.
