​KUSAN (“lake” or “inland bay”), a small group of North American Indian tribes, formerly living on the Coos river and the coast of Oregon. They call themselves Anasitch, and other names given them have been Ka-us or Kwo-Kwoos, Kowes and Cook-koo-oose. They appear to be in no way related to their neighbours. The few survivors, mostly of mixed blood, are on the Siletz reservation, Oregon.
