Now, English is the primary language spoken by the Kikiallus, with Lushootseed generally reserved for ceremonial activities.

[3] The traditional territory of the Kikiallus extended along the South Fork Skagit River to the confluence of the forks and the northern half of Camano Island, as well as some holdings on Whidbey Island near Strawberry Point.

[4][5] The Kikiallus also had villages at the confluence of the two forks of the Skagit River and at ʔəcəladiʔ (Utsalady Bay).

In 1916, the Kikiallus, represented by John Lyons, a descendant of the Snoqualmie leader Patkanim, sued the United States government regarding treaty rights.

[8] In 1950, Alfanso Sampson, an enrolled member of the Swinomish Indian Tribal Community, was elected as chief of the Kikiallus.
