The name q̓ʷətəms t̓ɩšosəm refers to the span from the mouth of the lake to the mouth of the river where it empties into the ocean. This water source meanders in a SW direction through the heart of t̓ɩšosəm and is one of the main water sources for the village. This creek is also home to the Tla'amin Salmon Hatchery since 1976. Salmonid species can be observed using this protected area for shade, shelter and insects required for fish spawning areas until the juvenile fish migrate seaward in the spring to support a myriad of other species. This creek and surrounding wetland areas filter our pollution and provide critical habitat for many of our traditional foods, medicines and materials. It is also a highly regarded spiritual area for sweat lodges, ceremonial bathing and many other cultural practices (information provided by Tla’amin Nation, 2025).
