The community was named in association with
Dal Ḵáahlii (formerly
Delkatla Inlet), a small arm of Masset Inlet, from a
X̱aad Kíl word meaning "water flowing in and out" or ""water drifting in to the inside" for the slough-like inlet which extends inland from the villages of
Ka-yung and
New Masset. The grassland at the head of the inlet is called
Delkatla Flats. The inlet is also known as
Delkatla Slough locally, and is fed by
Delkatla Creek (a term which in times past was used interchangeably for inlets and bays). ==History==
