Zenibako River
The Zenibako River (éŠå‡½å·) runs from Otaru, HokkaidÅ, HokkaidÅ, Japan and ends in the Sea of Japan. It is a Normal Class River of the Zenibako River System under Japanese River Law.
The Zenibako River originates north of Mount Okuteine, near the border with Sapporo City. It runs through mountain woods and meets the Zenibako-tÅge River (éŠå‡½å³ å·) as it emerges from the Zenibako Mountain Pass (éŠå‡½å³ , Zenibako TÅge). Katsuraoka-machi (桂岡町, Katsuraoka Town) is situated around the left bank of its middle course. The river turns eastward where it passes under the Sasson Expressway and National Route 5. It runs through the urban area of Zenibako, turns north, then enters the Ishikari Bay 200 meters southwest of Zenibako Station. The course lower than Route 5 was consolidated with concrete after the 1962 flood.
Biochemical oxygen demand of the water in 2004 was 0.1 mg/L, which means good condition.[1] Water of the upper stream is utilized by the Zenibako Purification Plant in Katsuraoka-machi for the east part of Otaru City's water service.[2] Water hardness of Zenibako is 29 mg/L.[3]
