The tribal name "Wenatchi" is of Yakama-Sahaptin origin, the neighboring Yakama named the "Wenatchapam Fishery"
Winátsha and the particular Wenatchi Band at this place
Winátshapam ("People at Winátsha"), the Wenatchi called this Band
Sinpusqôisoh. Therefore they were called in historic times also "P'squosa/Pisquouse". The individually distinct Wenatchi bands, are the following: • the
Stsilámuh ("People at the Deep Water, i.e. Lake Chelan") at the outlet of
Lake Chelan (
Tsilán - "Deep Water") • the
Sintiátqkumuh ("People from the place of grassy water") along
Entiat River (Ntiátq/Nt'yátkw/Nt'iátkw - "place of grassy water") • the
Siniálkumuh on the Columbia between Entiat River and Wenatchee River • the
Sinkumchímulh ("People at the mouth of [Wenatchee] River") at the mouth of the Wenatchee; • the
Sinhahamchímuh higher up on the Wenatchee; and • the
Sinpusqôisoh (already mentioned) at the forks of the Wenatchee, where the town of Leavenworth, Washington, now stands. They are closely related by language with the Entiat and Chelan peoples and through marriage and culture with Upper Yakima bands. Sometimes the
Chelan (
Ščəl̕ámxəxʷ - "People at the Deep Water, i.e. Lake Chelan") and
Entiat were considered simply as another Wenatchi Bands; the Entiat (also known as:
Inti-etook, Intietooks) - which called themselves ''Šntiyátkʷəxʷ (Sintia'tkumuk/Sintiatqkumuh)
("People from the place of grassy water/Gras in Water, i.e. Entiat River") and the Sinialkumuh'' Band of Entiat were often classed as "Wenatchi" or "P'squosa". Moreover, the Chelan people also described themselves as
Šntiyátkʷəxʷ ("People from the place of grassy water/Gras in Water, i.e. Entiat River"). In 1931, a
Powwow was held on the land of Mary Felix, a Wenatchi woman living in Yaksum Canyon in
Cashmere, Washington. It's estimated that nearly 700 Native Americans attended, including 250 Wenatchi, many traveling from the Colville and Yakama reservations. In 2024, the
Colville Confederated Tribes acquired 11 acres of land near Cashmere along the
Wenatchee River as part of an effort to reclaim ownership of ancestral lands. == Wenatchapam Fishery ==
