Ca·?aqu·?a means "swift or moving water" [where ca-aq means swift.] (Uchucklesaht Tribe Communications Coordinator, October 2008). The creek is also commonly called Silver Creek, and this stretch of shoreline is known as Silverside. (Uchucklesaht Tribe, December 2010).

The Uchucklesaht name for the mouth of this creek, and possibly extending along the north shore of Daller Point, is Taski·ha?a, meaning "slippery rocks" - a sacred and spiritual area for the Uchucklesaht Tribe (Uchucklesaht Tribe, December 2010). The common names Silver Creek and Silverside are likely a reference to the appearance of the slippery rocks here.
