Kanarra, later renamed Kanarraville, on Kanarra Creek, was first settled in 1861 and 1862. It was named for Piute Chief Canarrah or Quanarrah, but settlers spelled it Kanarrah or Kanarra. Its settlers were families driven from Fort Harmony when the fort had to be abandoned after most of its adobe walls were washed away during a month of heavy rains in January and February, during the Great Flood of 1862. New Harmony in Washington County was the other settlement created by refugees from this disaster.
