The Sinixt (also known as the Sin-Aikst or Sin Aikst, "Senjextee", "Arrow Lakes Band", or — less commonly in recent decades — simply as "The Lakes") are a First Nations People. The Sinixt are descended from indigenous peoples who have lived primarily in what are today known as the West Kootenay region of British Columbia in Canada and the adjacent regions of Eastern Washington in the United States for at least 10,000 years.
