The Clearwater River (Māori: Kairaumati) is on the West Coast of the South Island of New Zealand. The river originates on the northern slopes of Mount Mitchell on the western end of the Victoria Range, only one valley north of the Fox Glacier and Fox River.[1] Clearwater River and its tributary creeks drain land to the north of the Cook River / Weheka. The river flows under a bridge of SH 6 just north of the Fox Glacier township and passes close to Lake Matheson shortly after before flowing into Cook River / Weheka, which drains into the Tasman Sea.
