Source-derived summary

The Sinixt (sin-AYKST; also known as the Sin-Aikst or Sin Aikst, "Senijextee", "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. The Sinixt are of Salishan linguistic extraction, and speak their own dialect (snsəlxcín) of the Colville-Okanagan language.

Today they live primarily on the Colville Indian Reservation in Washington, where they form part of the Confederated Tribes of the Colville Reservation, which is recognized by the United States government as an American Indian Tribe. Many Sinixt continue to live in their traditional territory on the Northern Side of the 49th Parallel, particularly in the Slocan Valley and scattered amongst neighbouring tribes throughout BC, however the Canadian Government declared the Sinixt extinct in 1956.

History

Traditional territory

In her anthropological study of the Sinixt in Canada, Keeping the Lakes Way, Paula Pryce notes that "despite their obscurity in Canada and the scattered documentation of their presence in the area, both archival and published material show that the Sinixt Interior Salish resided along the Columbia River, Arrow Lakes, Slocan Valley, and parts of Kootenay Lake..." Other tribes used the Columbia as a trade route, passing through Sinixt territory to trade with the Sinixt and to trade further south. Parts of the traditional territory of the Sinixt are being claimed by the Westbank Band of the Okanagan people and as shared use and occupancy by the Ktunaxa. There is controversy over their historic claims to the area.

Traditional life

According to Lawney Reyes, the Sinixt numbered about 3,000 in the early 19th century, divided into several bands of sizes suited to hunting and fishing. He distinguishes the "Upper Sin-Aikst" around the Arrow Lakes, "above Revelstoke and around the Castlegar, Trail, and Slocan Valley area" from the "Lower Sin-Aikst in the Northport, Bossburg, Marcus, and Kettle Falls area in Washington State." The latter constituted "at least eight large bands".

Editorial summary

This brief starts where responsible research should: with the source description of “Sinixt” as ethnic group. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—1956—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Sinixt, ethnic and group can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as ethnic group. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 8, 2026. The linked authority identifier is Q1545880. The first chronological checks are 1956.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
